Researchers Describe Cases Of Transient Smartphone “Blindness.”
The AP reports that looking at a smartphone “while lying in bed at night could wreak havoc on your vision,” the findings of a letter published June 22 in the New England Journal of Medicine suggest. In the letter, physicians describe how “two women went temporarily blind” in one eye “from constantly checking their phones in the dark.” The NPR “Shots” blog reports, “Vision loss in one eye can be a sign that a person is having a small stroke” or may “also signal a compressed optic nerve.” But, “after further investigation, researchers…think the problem is” simply a case of “transient smartphone ‘blindness.’” The women were looking at their smartphones with “one eye covered because they were lying in bed.” That meant the retina in the eye looking at the smartphone “was adapted to light,” while the retina in the covered eye had adapted to the dark. HealthDay reports that the “optical trick” resolves in a few minutes and results in no lasting damage. People who do not know about this effect may mistakenly think they are having a transient ischemic attack and so might their physicians. To avoid experiencing the phenomenon, smartphone users should “look at the phone with both eyes.”LiveScience also covers the story.
Many Patients With DME May Be Undertreated, Research Suggests.

US Blindness, Visual Impairment Rates Projected To Double By 2050.
Popular Science reports that a new study by the National Institutes of Health and published online May 19 in JAMA Ophthalmology suggests that “blindness and visual impairment rates will double by 2050.” In “each decade for the next 35 years, the current population of visually impaired Americans (those with 20/40 or worse) will grow by 20 percent, from about 3.2 million in 2015.” Not included in this group are “the 16 million additional cases of correctable impairments like the nearsightedness and the farsightedness.” HealthDay reports that by 2050, investigators estimate that “2 million Americans will struggle with blindness; 7 million will have glaucoma, which damages the optic nerve, or age-related macular degeneration, which destroys the retina; and 16 million will have the wrong eyeglasses.” The leading factor behind increasing vision problems “is the growth and aging of the population.” Researchers arrived at these conclusion after having analyzed “data on men and women aged 40 and older from six studies on vision loss and blindness,” then “estimating” the future prevalence of such problems through 2050.
Few Cars Offer High Level Of Side-Window UV-A Protection, Study Suggests
HealthDay reports that research suggests that while “the front windshield of your car probably shields you from the sun’s UV-A rays as you drive…the same may not be true for side windows.” Investigators “analyzed the ultraviolet protection provided by the glass in 29 cars from 15 different automobile manufacturers.” Altogether, just “14 percent of the cars offered a high level of side-window UV-A protection.” The findings were published online in JAMA Ophthalmology. Reuters also covers the story.
Repeated Blows To Head May Cause Near Vision To Blur Slightly.
HealthDay reports that research suggests “repeated blows to the head can cause near vision to blur slightly, even if the individual impacts aren’t strong enough to cause a full-fledged concussion.” Over the course of “a regular football season, about two dozen college players developed a vision problem known as ‘near point of convergence,’ even though none suffered a concussion, according to the report which was published in JAMA Ophthalmology. HealthDay adds, “Near point of convergence occurs when the muscles that control the eyes – the ocular-motor system – are unable to perfectly align both eyes to focus on close-up objects, said senior researcher Keisuke Kawata, a PhD student.”

USA Today Share to FacebookShare to Twitter (8/21, Bowerman) reports that some 41 million Americans are estimated to wear contact lenses. Of that group, nearly “everyone is guilty of breaking the rules when it comes to contact care, according to a new survey Share to FacebookShare to Twitter from the Centers for Disease Control” published in the Aug. 21 issue of the CDC’s Morbidity and Mortality Weekly Report. People who wear contacts “answered questions in an online survey administered by the CDC in collaboration with the Contact Lens Assessment Youth group,” a survey that revealed that “99% of those surveyed are at risk for serious eye infections because of poor hygienic behaviors.” The NBC News Share to FacebookShare to Twitter (8/21, Fox) website reports that “nearly a third” of the adult contact lens wearers surveyed “admit they’ve gone to a doctor because of red or painful eyes,” and “half or more of wearers admitted they slept or napped while wearing lenses.” Better than half (55 percent) “said they just topped off solution instead of changing it and rinsing the case,” while 61 percent admitted to swimming with their contact lenses in. HealthDay Share to FacebookShare to Twitter (8/21, Preidt) reports that nearly 80 percent “admitted keeping their contact lens cases for longer than recommended, and more than half said they add new solution to the existing solution instead of emptying the contact lens case first.” All of these practices increase “the risk of eye infections by five times or more, according to the CDC.”
Protective Eyewear Requirement In Girls’ Field Hockey Results In Fewer Eye-Related Injuries, Study Says.
Reuters Share to FacebookShare to Twitter (8/18, Doyle) reports that the National Federation of State High School Associations’ 2011 mandate that required field hockey players to wear protective eye gear during high school-sanctioned field hockey competitions helped reduce injuries to and around the eye, according to a study Share to FacebookShare to Twitter published online in the journal Pediatrics. HealthDay Share to FacebookShare to Twitter (8/18, Haelle) reports that the study also “found that the odds of sustaining an eye injury were more than three times as high in areas where the mandate was not implemented compared with areas where it was implemented.” Researchers arrived at these conclusions after having “national and regional injuries for four seasons of girls’ high school field hockey,” including “the two seasons before the mandate for protective eyewear was implemented (2009-2010 and 2010-2011) and the two seasons after (2011-2012 and 2012-2013).”
Expert Discusses Importance Of Detecting AMD Early.
The Baltimore Sun Share to FacebookShare to Twitter (8/13, Cohn) interviews R. Ross Lakhanpal, MD, of the MedStar Union Memorial Hospital Eye Center, who discussed both the wet and dry forms of age-related macular degeneration (AMD), “the leading cause of vision loss in people over the age of 60.” Regular eye exams are important, because early detection leads to more successful treatment. While the disease cannot be cured, it can be treated with laser therapy and “anti-angionic” medications injected into the eye. Vitamin supplements have also been “found to be very effective in delaying and possibly preventing vision loss.” In fact, “the National Eye Institute’s Age-Related Eye Disease Study (AREDS) found that taking nutritional supplements with a specific high-dose formulation of antioxidants (vitamins C and E and beta-carotene), zinc, and copper delayed or prevented the progression of macular degeneration from the intermediate to the advanced stage.”
Eye Motion Test Could Detect Concussions.
The Minneapolis Star Tribune Share to FacebookShare to Twitter (8/7, Olson) reports that a study published in the online journal Concussion shows that a new eye tracking system can identify concussions with 88 percent accuracy, which is “superior to many commonly used screening tests.” Dr. Uzma Samadani, a neurosurgeon and TBI specialist at Hennepin County Medical Center, was the lead author of the research and says the data will be presented to the FDA in hopes of gaining Federal approval for clinical care. FDA officials have raised a variety of questions about the eye tracking system.
Only 57.6% Of Adults With Diabetes Report Having Had An Eye Exam In The Past Year, Survey Suggests.
Medscape Share to FacebookShare to Twitter (8/6) reports that “the number of people with diabetes who have visited an ophthalmologist or an optometrist to have their eyes checked within the last 12 months increases with age and longer disease duration but is still not optimal,” according to research Share to FacebookShare to Twitter (pdf) published online by the National Center for Health Statistics in an E-Stat report. The results of “the most recent National Health Interview Survey” also reveal that “overall, 57.6% of adults with diabetes reported having had an eye exam in the past year,” researchers reported.

The Wall Street Journal Share to FacebookShare to Twitter (8/4, D4, Lukits, Subscription Publication) reports that people taking a swim at the beach may end up needing medical attention to deal with eye infections, according to a study published in the Journal of Water and Health. Researchers arrived at this conclusion after analyzing data from more than 54,000 swimmers who visited nine beaches in the US.
Review: Patients Can Continue To Take Aspirin As Recommended By Their PCPs Without Fear Of Worsening Macular Degeneration.
Medscape Share to FacebookShare to Twitter (7/17, Harrison) reports, “Patients can continue to take aspirin as recommended by their primary care physicians [PCPs] without fear of worsening their macular degeneration,” according to a review of “197 cardiovascular studies with 167,582 subjects and four ophthalmologic studies with 13,175 subjects.” In fact, “in the meta-analysis of all these studies, the possible risk for macular degeneration was outweighed by the well-established cardiovascular benefits.” The findings were presented earlier this week at the American Society of Retina Specialists’ annual meeting.
Implantable Miniature Telescope May Be Effective In Patients With Bilateral AMD Younger Than Age 75.
Medscape Share to FacebookShare to Twitter (7/14, Harrison) reports, “For patients with bilateral late-stage age-related macular degeneration (AMD), an implantable miniature telescope is effective in patients younger than 75 years, according to results of a five-year study” that involved “217 patients who underwent implantation in one eye; the fellow eye served as the control group.” The study also stratified patients “by age at study enrollment: 75 years and older, 65 to 75 years, and younger than 65 years.” The research Share to FacebookShare to Twitter was presented at a medical meeting and published online in the Journal of Clinical Ophthalmology.
Summer Sun Poses Significant Issues For Eye Health And Vision.
In “The Blog” for the Huffington Post Share to FacebookShare to Twitter (7/7), author Kim Dramer writes that “summer sun poses significant issues for eye health and vision.” To protect “vision during the summer months and beyond” from the harm caused by ultraviolet rays, including photokeratitis and long-term problems, such as cataracts, age-related macular degeneration, and even cancer, the American Optometric Association (AOA) provides guidelines recommending the use of sunglasses, wearing a hat, and using sunscreen on the skin around the eyes. In addition, Andrea Thau, OD, “president-elect of the AOA and Associate Clinical Professor at State University of New York College of Optometry, provides an eye health primer for understanding the dangers posed by summer sun and protecting your eye health and vision as well as that of your child during summer vacation.”
Digital Devices Taking A Toll On Getting A Good Night’s Sleep.
In its “Sleepless in America” special series, NBC Nightly News (6/24, story 9, 2:45, Holt) reported, “The CDC has called lack of sleep a public health epidemic, and most sleep experts say all our digital devices we’re taking into the bedroom are taking a toll on getting a good night’s rest.” NBC News correspondent Hallie Jackson explained, “Experts say it’s no coincidence 95 percent of us look at some kind of screen within an hour of bedtime and 85 percent have trouble falling asleep.” Blue light emitted from “screens send[s] a signal it’s still daylight, triggering a surge of energy and blocking the melatonin that makes us sleepy.” Therefore, it’s “no wonder then that with the device on nearly every nightstand one in three people sleeps less than six hours a day, raising the risk for diabetes, heart disease, obesity and depression.”.
CDC: Chloramines In Swimming Pool Water May Irritate Eyes, Skin.
The ABC News Share to FacebookShare to Twitter (6/25, Mohney) website reports that people using swimming pools often “end up with red eyes or even skin irritation,” and the cause is “probably not the chlorine” used in pool water. The CDC “advises Share to FacebookShare to Twitter that what is especially irritating for swimmers is when chlorine mixes with body fluids including sweat or even urine.” The resulting “by-products, called chloramines, appear in the water or even in the air near a pool.” Swimmers who do not use goggles “should be careful to keep their eyes shut underwater.” Chloramines in the air may irritate people’s airways, too, posing a risk for people with asthma.
Sunglasses May Help Prevent Many Eye Diseases, Cancer On Eyelid.
The Chicago Tribune (6/7, Carlson) reported on the importance of sunglasses “having 100 percent protection from UVA and UVB light (also called UV 400 block).” That is because “properly fitting sunglasses go a long way to preventing many eye diseases, including cataracts, macular degeneration and cancers related to the iris and eyelid.” Samuel Pierce, OD, “on the board of trustees for the American Optometric Association, said about 10 percent of skin cancers are around the eyelid, as damage from ultraviolet rays is accumulated over a lifetime of exposure, which is why parents should try to put sunglasses on children, including babies.”
Surge In Popularity Of Air-Powered Replica Firearms Leads To Increase In Eye Injuries.
The Wall Street Journal Share to FacebookShare to Twitter (5/29, Jones, Subscription Publication) reported that air-powered replica guns have surged in popularity, leading to huge increases in associated eye injuries with the firearm replicas. According to Stanford University medical researchers using US Consumer Product Safety Commission data, non-powder replica gun eye injuries have increased by 500% between 2010 and 2012.
Metformin Use Linked To Lower Risk For Glaucoma.
Health Day Share to FacebookShare to Twitter (5/29, Reinberg) reports that metformin may be “linked to a lower risk of developing…glaucoma,” according to a study Share to FacebookShare to Twitter published online in JAMA Ophthalmology. In the study, which included some 150,000 individuals with diabetes, “people who took the most metformin during the 10-year study period had a 25 percent reduced risk of glaucoma compared with people not taking the” medication.
Analysis Reveals Chronic Health Conditions Discovered During Eye Examinations.
LifeHealthPro Share to FacebookShare to Twitter (5/19) reports that by “looking at the experience of 820,000 enrollees who had both UnitedHealthcare medical and vision coverage for at least 670 days in 2011 and 2012, and who started 2011 without having any chronic condition diagnosis,” analysts at UnitedHealth’s UnitedHealthcare unit discovered that “52,408 of the enrollees, or 6.4 percent, received chronic condition diagnoses, and that 2,612, or 5 percent of the enrollees who received chronic condition diagnoses, first learned about the conditions when they saw eye care providers.” High cholesterol, hypertension, and diabetes were three health conditions discovered during eye examinations.
More Children Around The World Becoming Nearsighted.
The Wall Street Journal Share to FacebookShare to Twitter (4/20, Wang, Subscription Publication) reports on the increased numbers of children with myopia, particularly in Asia. Even in the US, the rate of myopia has increased in teens and adults by approximately 66 percent between studies almost 30 years apart, according to the National Eye Institute’s own research. Some experts believe that children spend too little time outdoors. Sunlight helps dopamine release substances that stop eyes from becoming nearsighted.
ChiTrib: US Kids Should Spend More Time Outdoors To Avoid Becoming Nearsighted.
The Chicago (IL) Tribune Share to FacebookShare to Twitter (4/11) editorialized that in 2004, a study conducted by the National Eye Institute found that 42 percent of Americans had “some degree” of nearsightedness. Numerous studies in people and in animals are now suggesting that sunlight allows for the release of dopamine within the retina, thus preventing the eye from becoming “misshapen during development.” Unfortunately, “dim indoor lights disrupt this cycle, stripping the eye of the dopamine’s protection during the day.” One Australian researcher claims that spending just three hours outdoors each day would help prevent some of children’s risk for developing myopia. These days, most US kids are outdoors far less time than that, the Tribune observed.
Calcium Supplementation May Be Linked To Higher Risk Of Macular Degeneration.
Medscape Share to FacebookShare to Twitter (4/11, Laidman) reported that research suggests that people “who take more than 800 mg of calcium daily are almost twice as likely to be diagnosed with age-related macular degeneration (AMD) as those who” do not. The findings were published online in JAMA Ophthalmology.
Expert Discusses How Certain Vitamins, Minerals May Lower AMD Risk.
In the Wall Street Journal (4/7, D3, Mitchell, Subscription Publication), Emily Y. Chew, of the National Eye Institute, discusses the results of the Age-Related Eye Disease Study that found that certain vitamins and minerals lowered the risk for age-related macular degeneration (AMD). She also talked about the follow-up study in which zeaxanthin and lutein were added to the previous study’s supplement formulation, lowering the risk for AMD even further. Finally, she recommended that people consume leafy greens and fish often during the week.
Simple Formula May Predict Which Kids Will Become Nearsighted By Age 13.
The Today Show Online Share to FacebookShare to Twitter (4/3, Fox) reports that in research published online April 2 in JAMA Ophthalmology, investigators have arrived at “a simple formula for predicting which children will need glasses as they hit middle school: measure how farsighted they are in the first grade.” After studying some 4,500 youngsters for over 20 years, researchers found that “measuring their vision at around age six can predict which kids will become nearsighted by the age of 13.” The NPR Share to FacebookShare to Twitter (4/3, Shute) “Shots” blog reports that the study, which was funded by the National Institutes of Health, found that “children whose refractive error was less than +0.75 diopters (which is slightly farsighted) in first grade were most likely to become nearsighted.” Medical Daily Share to FacebookShare to Twitter (4/3, Caba) reports that investigators “assessed 13 potential risk factors, including physical measures of the eye and reports from parents regarding their child’s activities, to decide on the strongest predictor or set of predictor for nearsightedness.” Even though “all 13 risk factors did increase each child’s risk for nearsightedness, certain predictors were more important than others, such as two nearsighted parents.” Still, “the child’s eyeglasses prescription at baseline was the strongest predictor for if a child would develop nearsightedness before” adolescence. The Telegraph (UK) Share to FacebookShare to Twitter (4/3, Knapton) also covers the story.
Google Testing Smart Contact Lenses That Measure Glucose Levels In Users’ Tears.
TIME Share to FacebookShare to Twitter (3/25, Sifferlin) reports that Google has been awarded “a patent for a contact lens with an embedded chip” that may help measure glucose levels in people with diabetes. The company “has been testing various prototypes of smart contact lens and is currently in talks with the US Food and Drug Administration (FDA) about a lens that measures glucose levels in users’ tears.” Google “says the chip and sensor are embedded between two layers of contact lens material and a tiny pinhole lets tear fluid from the eye reach the glucose sensor, and the sensor can measure levels every second.”
Company Claims New Laser Treatment Can Change Brown Eyes Into Blue Eyes.
TIME Share to FacebookShare to Twitter (3/6, Poppick) reports that California-based Stroma Medical claims that “a new treatment has successfully changed the color of people’s eyes in Latin America.” In the US, however, the FDA has not approved the procedure. Stroma “claims that it has conducted 37 successful treatments on patients in Mexico and Costa Rica” with a laser treatment that “turns brown eyes blue.” The 20-second, $5,000 procedure “works by disturbing the thin layer of pigment that exists on the surfaces of all brown irises.” Results are not instantaneous. It takes several weeks after the procedure for the eyes to turn blue. While the company maintains the procedure is safe, some eye experts have expressed caution that the procedure could result in increased ocular pressure and a higher risk for glaucoma.
Differences In Dress Color Perception Based In Science.
CNN Share to FacebookShare to Twitter (2/27, Cohen) reported on the social media debate concerning the “colors in the now-famous dress,” and said “there’s a scientific explanation” behind the perception differences. The differences reportedly “have to do with the tiny cones in the back of our eyeballs that perceive colors in a slightly different way depending upon our genes.” Dr. Emily Chew, the deputy director of the division of epidemiology and clinical applications at the National Eye Institute, however, “said in more than 30 years of research she’s never seen an image where people, all with normal vision, have had such dramatically different responses.” She continued, “It would be interesting to use this image to learn more about the pathways of how we understand color.”
Function Of Eyelashes May Be To Help Protect Eyes From Drying Out.
The New York Times Share to FacebookShare to Twitter (2/25, A12, Gorman, Subscription Publication) reports that research published Feb. 24 in the Journal of the Royal Society Interface suggests that “the real function” of eyelashes “is to help protect eyes from drying out.” Researchers discovered that “across a wide variety of mammals, eyelashes are always about one-third as long as the eye is wide, which, it turns out, is the ideal length for diverting airflow around the eye and reducing evaporation.”
AOA Estimates One In Four Kids Has A Vision-Related Issue.
The Oklahoman Share to FacebookShare to Twitter (2/17) reports, “The American Optometric Association estimates that one in four children has a vision-related issue.” Children with “uncorrected vision” may face “social, academic, behavioral, physical and athletic” problems. The AOA suggests that kids “first see an optometrist between six months and one year of age, and once every a year to 18 months afterward.”
Breathing Slowly, Deeply May Help People With Dry-Eye Disease Produce More Tears.
The Wall Street Journal Share to FacebookShare to Twitter (2/3, Lukits, Subscription Publication) reports that a 20-patient study Share to FacebookShare to Twitter published in the journal Ocular Surface suggests that breathing deeply and slowly may help people with dry-eye disease secrete more tears. Deep, slow abdominal breathing helps calm the autonomic nervous system which in turn controls the parasympathetic system and makes it easier for the lacrimal glands to produce tears. The National Eye Institute points out that some 12 million people in the US may have dry-eye disease.
Tracking Eye Movements May Help Detect Concussions.
Forbes (1/30) contributor Robert Glatter, MD explains that “researchers from NYU have developed a new approach using novel eye tracking technology that can spot abnormalities in eye movements which may represent the earliest signs of concussion,” and that “additional information obtained from abnormalities of eye movements may…be used to quantify the severity of a concussion,” according to study published online Jan. 29 in the Journal of Neurotrauma. For the study, researchers “evaluated 75 patients (between the ages of 18 and 60) in the emergency department at Bellevue Hospital Center in New York City, who had sustained head trauma and compared them with 64 healthy control subjects.”
HealthDay (1/30, Preidt) reports that “the movements of the participants’ pupils were tracked while they watched a music video for a few minutes.” Interestingly, 13 “trauma patients who hit their heads and had CT scans showing new brain damage, and 39 trauma patients who hit their heads and had normal CT scans, were much less able to coordinate their eye movements than trauma patients who hadn’t hit their heads and those in the control group.” And, “the more severe the concussion, the worse a patient’s eye movement problems.”
AOA Condemns Practice Of Eyeball Tattooing.
BBC News Share to FacebookShare to Twitter (1/16, Jolly) reports on eyeball tattoos, a technique which “involves injecting pigment directly into the eyeball so it rests under the eye’s thin top layer, or conjunctiva.” A few injections are needed “to completely cover the sclera, which is then coloured for life.” BBC News points out that “the American Optometric Association unequivocally condemns the practice, saying it puts the patient at risk of infection, inflammation and blindness.”
Long-Term Hypertension May Increase Risk Of Glaucoma.
HealthDay Share to FacebookShare to Twitter (1/8, Preidt) reports that research published in Investigative Ophthalmology & Visual Science suggests that “long-term high blood pressure may increase the risk of…glaucoma.” The investigators “said their findings suggest that doctors should consider a patient’s blood pressure when managing glaucoma.”
Small Study: Using E-Readers Before Bedtime May Disrupt Sleep Patterns.
The Wall Street Journal Share to FacebookShare to Twitter (12/23, D3, Beck, Subscription Publication) reports that according to a study Share to FacebookShare to Twitter published online in the Proceedings of the National Academy of Sciences, reading a real book printed on paper may be much less disruptive of sleep than reading from a tablet computer or e-book reader. The New York Times Share to FacebookShare to Twitter (12/23, Bakalar) “Well” blog reports that after randomizing “12 healthy young adults to one of two activities: reading a light-emitting e-book in a dimly lit room for about four hours before bedtime on five consecutive evenings, or reading a printed book for the same amount of time,” researchers found that “compared with a printed book, a light-emitting e-book decreased sleepiness, reduced REM sleep (often called dream sleep), and substantially suppressed the normal bedtime rise of melatonin, the hormone that regulates the sleep and wake cycle.” People who read e-books reported feeling groggier and less alert in the morning. The Los Angeles Times Share to FacebookShare to Twitter (12/23, Mohan) “Science Now” blog reports, “Although the study used only iPads, in separate tests the researchers found that iPhones, iPods, the Nook Color and the Kindle Fire all had similar short-wavelength emissions.”
Expert Panel Recommends Eye Screening For Preschool Kids.
HealthDay Share to FacebookShare to Twitter (12/20, Preidt) reported that according to recommendations made by an expert panel of the US National Center for Children’s Vision Health in the January issue of the journal Optometry and Vision Science, all youngsters “should have their eyesight checked between the ages of three and six, preferably every year.” The authors of the recommendations pointed out that “early detection and treatment of vision problems is important in terms of a child’s development and readiness to school.”
Most Americans Not Incorporating Foods, Supplements Into Diet For Eye Health.
KY Forward Share to FacebookShare to Twitter (12/19) reports that “according to a 2014 survey from the American Optometric Association, 73 percent of Americans do not incorporate any specific foods or supplements into their diet to help improve eye health or vision,” even though “six nutrients ― antioxidants lutein and zeaxanthin, essential fatty acids, vitamins C and E and the mineral zinc ― have been identified as helping to protect eye sight and promote visual health.” Optometrist Leslie Cecil, OD, said, “Since the body doesn’t make these nutrients naturally, it’s important that they are incorporated into your daily diet and, in some cases, supplemented with vitamins.”
FDA Warns Toy Lasers Can Damage Eyesight.
The Hill Share to FacebookShare to Twitter (12/19, Devaney) reports that the FDA has issued safety guidance Share to FacebookShare to Twitter “to protect children playing with toy laser guns and lightsabers,” which the agency says “can cause someone’s eyesight to slowly deteriorate over time.” The agency wrote, “Lasers with outputs above certain levels that are operated in an unsafe and uncontrolled manner may cause injury to the user and others within range of the laser beam” and “this is a particular concern for lasers intended for entertainment purposes, especially when intended to be used as toys by children.”
AOA Stresses Importance Of Full Vision Exams For Babies, Toddlers.
The Pittsburgh Tribune-Review Share to FacebookShare to Twitter (12/9, Gormly) reports that while more and more younger children are being diagnosed with vision problems, “medical professionals and parents are catching the problems earlier than they did in previous generations.” The American Optometric Association “recommends babies get a full vision exam when they are six months and 12 months old, then annually after that.” That is because “basic vision screenings, like those done at schools and at standard pediatrician well visits, don’t give a thorough enough picture of the eye’s health and functioning…says” Andrea Thau, OD, vice president of the AOA. Dr. Thau pointed out the importance of detecting vision problems in little ones early, because “vision is the primary sense” used in learning.
Patients With Allergic Eye Symptoms May Also Have Concomitant Dry Eye Disease.
Medscape Share to FacebookShare to Twitter (11/12, Johnson) reports that according to a study presented at the annual meeting of the American College of Allergy, Asthma & Immunology, “patients with allergic eye symptoms can also have concomitant dry eye disease, and the combination of the two conditions often means that symptoms are more numerous and more severe.” Investigators came to this conclusion after comparing “the prevalence and severity of dry eye disease in a national cohort of 9216 ophthalmology patients (mean age, 55 years) and 68 allergy patients (mean age, 49 years).”
Bonnet Syndrome Examined.
Paula Span, in a piece for the New York Times Share to FacebookShare to Twitter (11/8, Span), explained that Bonnet Syndrome causes patients to hallucinate, much like dementia patients, though the source of the visions is related to diminished eye sight. The condition affects about 10-15% of older patients experiencing macular degeneration, glaucoma, or cataracts. The visions often go away after one or two years, according to Dr. Abdhish Bhavsar, spokesperson for the American Academy of Ophthalmology.
Study Examines Dangers Of Detergent Pods To Kids.
The New York Times Share to FacebookShare to Twitter (11/10, A16, Saint Louis, Subscription Publication) reports on the dangers posed by “colorful, single-load packets of” detergents introduced on the US market about two years ago. Since the pods’ introduction, “more than 17,000 children under age six ate or inhaled the contents or squirted concentrated liquid from a packet into their eyes, “ according to a study published online in the journal Pediatrics. For the study, researchers compiled “all cases reported to the National Poison Data System,” finding that the problem was not “uncommon” and may even be under-reported, since information reported to the NPDS is voluntary. USA Today Share to FacebookShare to Twitter (11/10, Painter) reports that the single-use pods “sent an average of one child a day to hospitals in 2012 and 2013,” the study found. Even though there are not any numbers for this year available yet, “the danger persists, says lead researcher Gary Smith, director of the Center for Injury Research and Policy at Nationwide Children’s Hospital in Columbus,” OH. Youngsters at the most risk are toddlers under the age of two, who may think the colorful pods resemble candy or a juice product. The Wall Street Journal Share to FacebookShare to Twitter (11/10, B1, Ziobro, Subscription Publication) reports on the front of its Marketplace section that the study tied one death to a detergent pod and revealed that about 4.4 percent of children ended up in the hospital after trying to ingest one. The piece also describes steps taken by certain pod-detergent manufacturers to make containers holding the pods opaque and much harder for little hands to open. The AP Share to FacebookShare to Twitter (11/10, Tanner) reports that despite whatever precautions the pods’ manufacturers take to made the products safer, “the Consumer Product Safety Commission says children should not be allowed to handle the packets and advises parents to store them out of children’s sight and reach.” Also covering the study are Reuters Share to FacebookShare to Twitter (11/10, Seaman), the Washington Post Share to FacebookShare to Twitter (11/10, Barbash) “Morning Mix” blog, and the Syracuse (NY) Post-Standard Share to FacebookShare to Twitter (11/10, Mulder).
Ortho-K Treatment May Help Slow Myopia’s Progression In Teens.
The New York Times Share to FacebookShare to Twitter (11/4, D6, Bhanoo, Subscription Publication) reports that myopia is on the increase across the US, for reasons unknown. Epidemiologist Susan Vitale, PhD, MHS, of the National Institutes of Health, said, “It’s probably something that’s environmental, or a combination of genetic and environmental factors.” According to some studies, “‘near work’ — reading, computer work, playing video games, and using tablets and smartphones — is contributing to the increase.” To help prevent or at least slow myopia in teenagers, eye doctors offer orthokeratology (ortho-k) treatment in which special “contact lenses apply pressure to the cornea, flattening it.” Patients wear the lenses overnight and enjoy clear vision for the next day. Teens who undergo the treatment may end up less nearsighted than their peers who wear glasses or regular contact lenses.
AOA consumer campaign warns of illegal contact lenses
Consumers think decorative contact lenses complete their scary Halloween costumes, but what’s truly frightful are the consequences from circumventing eye doctors to purchase lenses illegally.According to the AOA’s 2014 American Eye-Q® survey, more than one in ten consumers report wearing decorative contact lenses, and, of those, half purchased lenses without a prescription—all the more reason to educate consumers about the dangers of improper usage and reinforce the recommendation to visit an OD to obtain a valid prescription for lenses.
Study: Laundry Detergent Pods Can Injure Children’s Eyes.
NPR Share to FacebookShare to Twitter (10/7, Shute) reports in “Shots” blog on a study Share to FacebookShare to Twitter that emphasizes the potential risk of laundry detergent pods to children. The pods entered the US consumer market in 2012 and may seem like a toy to children, who can rupture the packaging either through squeezing or biting, which can result in eye injuries that are often worse than those caused by bottled detergents. The study is in this month’s issue of the Journal of the American Association for Pediatric Ophthalmology and Strabismus.
FDA Approves Eye Implant To Treat Diabetic Macular Edema.
The AP Share to FacebookShare to Twitter (9/26) reports Alimera Sciences and pSivida disclosed Friday that the FDA approved “their eye disease implant Iluvien.” According to the piece, Iluvien is an implant delivered by injection aimed at treating “diabetic macular edema, a condition that can cause blurred vision and blindness.” Reuters Share to FacebookShare to Twitter (9/26) reports that during the treatment physicians insert a small cylindrical tube with medicine on the back of the eye, the spot where diabetic macular edema usually forms.
Number Of Toddlers Needing Glasses Expected To Rise.
The Wall Street Journal Share to FacebookShare to Twitter (9/24, Byron, Subscription Publication) reports that physicians predict the number of toddlers needing glasses will rise as diagnostic tools improve and optometrical health awareness grows. A 2011 study published in the journal Pediatrics found that as many as one in every 20 preschool-aged children has a vision issue. To catch issues early, the American Optometric Association recommendation is that babies should see an optometrist between the ages of six and 12 months, and annually as normal after that.
Importance Of Early Eye Exams For Kids Emphasized.
Reuters Share to FacebookShare to Twitter (9/20, Harlan) reported on the importance of early eye examinations for children, particularly because most vision issues in youngsters are treatable and often even preventable. Optometrist Ida Chung, OD, president of the College of Optometrists in Vision Development, suggested that little ones undergo their first eye examination before their first birthday. For older kids, the American Optometric Association provides a suggested schedule of eye exams on its website.

HealthDay Share to FacebookShare to Twitter (8/23, Doheny) reported that according to the results of a 35-patient study recently published online in the journal Plastic and Reconstructive Surgery, “cosmetic eyelid surgery involving specific nerves…may also provide migraine relief.” The surgery “involves making incisions in the upper eyelid to deactivate so-called ‘trigger’ nerves.” In addition, it “lifts the lid, a technique known as blepharoplasty.”
Loss Of Visual Acuity Tied To Increased Risk Of Earlier Death In Seniors.
The NPR Share to FacebookShare to Twitter (8/21, Shute) “Shots” blog reports that according to a study Share toFacebookShare to Twitter published online Aug. 21 in JAMA Ophthalmology, “an eye exam may be the ticket to a longer life…because good vision is essential for being able to shop, manage money and live independently.” Independent living “in turn leads to a longer life.” The study found that individuals 65 to 84 years of age “who lost visual acuity equivalent to one letter on an eye chart each year had a 16 percent increase in mortality risk over eight years, and that was due to the loss in independent living abilities.” HealthDay Share to FacebookShare to Twitter (8/22, Preidt) reports that the study authors believe “the study reinforces the notion that if a senior is burdened by impaired sight, helping them complete everyday tasks may be important to maintaining long life.”
Small Study: Eye Test May Help Test For AD/HD.
Medscape Share to FacebookShare to Twitter (8/21, Brooks) reports that according to a study published in the August issue of the journal Vision Research, “a simple test examining involuntary eye movements may provide an objective way to tell whether individuals have attention-deficit/hyperactive disorder (AD/HD) and whether stimulant medication will be an effective treatment.” After recording “involuntary eye movements in 22 adults with AD/HD with and without methylphenidate and 22 control individuals while they performed the test of variables of attention,” researchers “observed increased microsaccades and blink rates in adults with AD/HD, which normalized with methylphenidate treatment.”
Expert Advises Parents On Contact Lenses For Kids.
HealthDay Share to FacebookShare to Twitter (8/16, Preidt) reported that when youngsters “ask if they can have contact lenses, parents need to carefully consider the pros and cons.” Optometrist Bernard Lepri, OD, of the Food and Drug Administration, said that parents “need ‘to remember that contact lenses are medical devices, not cosmetics.” Dr. Lepri added, “Like any medical device, contact lenses should be used only if they can be used safely and responsibly.

WellPoint offers 6 tips for handling digital eye strain
Publish date: FEB 11, 2014PrintIndianapolis, IN—Digital eye strain is caused by the overuse of digital devices such as computers and smartphones. Because these electronic devices are designed to be used and held within close range of the eyes, after a while, the eyes become strained as they continue to refocus to process the images on the digital screen.According to organizations like The Vision Council, more than 70% of Americans don’t know or don’t believe they are at risk for digital eye strain; however, anyone who is in front of a digital screen is vulnerable. Red eyes, twitching eyes, dry eyes, blurred vision, headaches, neck pain, decreased productivity and increased work errors, fatigue from staring at a digital screen, and straining to see small fonts and images are some of the signs and symptoms that occur when experiencing digital eye strain.“In our fast-paced society, most people use a computer throughout the day while they’re at work, and they also go online to communicate with friends, read books, and even pay bills,” said Dr. Richard Hom, optometric director for WellPoint. “It’s just the way we operate in the 21st century. Nevertheless, people can stay digitally connected and also maintain the health of their eyes.”Dr. Hom suggests the following tips for avoiding digital eye strain:1. Follow the “20-20-20 rule.” Be mindful of the amount of time that is spent looking at a computer screen without taking a break. Every 20 minutes, take a 20-second break and look at something that is 20 feet away. Looking far away relaxes the focusing muscle inside the eye and reduces eye fatigue.2. Reduce glare. People often see reflections from objects around their computer on their computer screen. Install an anti-glare screen on the computer monitor to reduce glare on the screen. Cover windows with drapes and blinds, and use a computer hood to block some of the overhead and peripheral light. Get anti-reflective (AR) coating on eyeglass lenses.3. Work in proper lighting. When looking at a digital screen, the surrounding light should be half as bright as what is typically found in most offices. Try to position the computer screen so windows are on the side (instead of in front or behind) the computer screen. If the interior lighting is a concern, consider reducing the number of fluorescent tubes that are installed above the computer. Also consider turning off the overhead fluorescent lights in the office and use lamps that provide halogen or incandescent lighting, or switch to lower intensity bulbs.4. Blink often. People tend to blink less often when they look at a computer screen—approximately one third less often as they normally blink—and a lot of the blinking that takes place when looking at a digital screen are only partial lid closures. Blinking less often can cause the eyes to become dry. To reduce the chances of experiencing dry eyes when looking at a digital screen, try this exercise: Every 20 minutes, blink 10 times by closing the eyes very slowly, as if falling asleep. This will moisten the eyes, and it will also help the eyes refocus.5. Revise the workspace. When working on a computer, people often look back and forth between the computer screen and a printed page, which can cause eye strain. To alleviate the stress and strain on the eyes, put the printed pages on a copy stand that is next to the computer monitor. Make sure the paper on the copy stand is well-lit by using a desk lamp. Poor posture can also lead to problems with clearly seeing a digital screen. Consider purchasing ergonomic furniture where the computer screen is positioned 20 to 24 inches from the eyes. The center of the digital screen should be 10 to 15 degrees below the eyes.6. Get a regular comprehensive eye exam. According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have eye exams once a year. Before the exam, be sure to measure the distance between the eyes and the digital screen. Share that measurement with the eyecare provider, and remember to let the doctor know how often computers and smartphones are used.

Regular Aspirin Use May Be Linked To Increased Risk Of “Wet” Age Related Macular Degeneration.
BBC News (1/22, Gallagher) reports, “People who regularly take aspirin for many years, such as those with heart problems, are more likely to develop” “wet” age-related macular degeneration, according to a study published in JAMA Internal Medicine. — HealthDay (1/22, Reinberg) reports, “People taking aspirin for heart and stroke prevention benefits should not be alarmed, however…said” study senior researcher Jie Jin Wang. According to Wang, “Currently, there is insufficient evidence to recommend changing clinical practice, except perhaps in cases of patients with strong risk factors for age-related macular degeneration, such as existing age-related macular degeneration in one eye.”
Increase In Visual Impairment In US Tied To Diabetes.
Print media covered a study suggesting that an increasing percentage of Americans are losing their eyesight due to the complications of diabetes. Because diabetes rates are on the rise, so are the complications of the illness, including those that affect eyesight.USA Today (12/10, Szabo, Today) reports, “The nation’s twin epidemics of obesity and diabetes are beginning to rob more Americans of their sight,” according to a study published Dec. 12 in the Journal of the American Medical Association. “The percentage of American adults suffering from uncorrectable vision loss spiked 21% in only about six years, rising to nearly 1.7% of the population, according to an analysis of the years 1999-2002 to 2005-08.” However, “rates of visual impairment doubled among poor people and those who had had diabetes for a decade or more,” the study found.
Better Vision Associated With Health Plans Covering Eye Exams.
HealthDay (12/11, Preidt) reports, “Working-age adults who have vision insurance have better eyesight than those without insurance,” according to a study published online Dec. 10 in the Archives of Ophthalmology. After studying data on “more than 30,000 people, aged 40 to 64, in the United States,” researchers found that “people with vision insurance were more likely to report having periodic eye examinations and, on average, those who had such a checkup in the previous year had better eyesight.”MedPage Today (12/11, Neale) points out that even though “periodic eye exams are recommended to detect and treat various conditions that can cause vision impairment or loss, vision coverage is often not part of medical insurance plans, throwing up a potential barrier to screening.”
Gene Therapy May Someday Correct Colorblindness.
On the front of its Personal Journal section, the Wall Street Journal (11/6, D1, Beck, Subscription Publication) reports in “Health Journal” that gene therapy may someday help make colorblind people see the colors red and green. In 2009, vision researchers at the University of Washington were able to restore red-green color vision to squirrel monkeys by injecting a missing gene into a virus inserted into the animals’ retinas. The animals still can see the colors red and green today. The piece also points out that red-green colorblindness is the most common kind of colorblindness. This X-chromosome linked colorblindness predominantly affects men. Now, new tools, apps, contact lenses and special eyeglasses at Vision Care Consultants can help people with colorblindness recognize certain colors.
Digital Tablets May Help Improve Reading Speed In Low Vision.
HealthDay (11/13, Preidt) reports, “Digital tablets such as iPads and Kindles can boost reading speed in people who have eye diseases that damage their central vision,” according to a study presented at a recent ophthalmology meeting. “Researchers looked at 100 people with this type of vision loss and found that their reading speed increased by at least 42 words per minute when they used the iPad tablet on the 18-point font setting, compared with reading a print book or newspaper,” while “their reading speed increased by an average of 12 words per minute when they used the Kindle tablet set to 18-point font.” WebMD (11/13, Mann) reports, “The backlight boosts contrast sensitivity or the ability to see an object stand out from its background. Many people with low vision lose this ability,” said researcher Daniel Roth, MD, of the Robert Wood Johnson School of Medicine. He explained, “The findings apply to anyone with compromised reading vision who has difficulty seeing letters or words.” He added, “The magnified font and backlight allows them to improve their reading ability and comfort.”
FDA Issues Halloween Warnings On Contact Lenses
The York (PA) Daily Record (10/25, Zaleski) notes that the Food and Drug Administration “regulates all contact lenses — including decorative ones — because they are medical devices under the Federal Food, Drug, and Cosmetic Act.” With Halloween just around the corner, the agency has released a consumer update (pdf) about decorative lenses, which “pose risks, including allergic reactions, corneal abrasion, infection, decreased vision and blindness.” For those who are interested in wearing decorative contact lenses, the FDA update provides tips to ensure they are purchased safely. Notably, FDA spokesperson Sarah Clark-Lynn says, “Anyone selling contact lenses must get a prescription from the buyer and verify it with the customer’s doctor.”
AOA Points Out Risks Of Special-Effects Contact Lenses For Halloween.
On its website, KTAR-FM Phoenix (10/9, Haros) reported that the Food and Drug Administration “has been keeping tabs on the sale of theatrical or special-effects contacts since 2005.” Now, with Halloween approaching, many people may be tempted to buy them. These contact lenses, available online and at street vendors without prescription, may be dangerous. “According to the American Optometric Association, ‘Risks associated with the improper use of decorative, or prescribed corrective contact lenses include conjunctivitis, swelling, allergic reaction and corneal abrasion due to poor lens fit.'” Their use “may result in a reduction of visual acuity [sight], contrast sensitivity and other general eye and vision impairments,” the AOA warns.
Lutein, Zeaxanthin Supplementation May Improve Retinal Function In Early AMD.
Medscape (10/2, Brown) reports, “Lutein and zeaxanthin supplementation could improve early functional abnormalities of the central retina in patients with early age-related macular degeneration (AMD), according to a randomized, double-masked, placebo-controlled trial that studied the effects of 48 weeks of lutein and zeaxanthin supplementation on retinal function by multifocal electroretinography (mfERG) in patients with early AMD.” Chinese researchers “studied the effects of 48 weeks of lutein and zeaxanthin supplementation on retinal function by multifocal electroretinography (mfERG) in patients with early AMD” and “published their findings in the October issue of the American Journal of Ophthalmology.”
Contact Lens Users At Risk For Acanthamoeba Infection.
The Daily Mail (UK) (9/7, Macrae) reports, “Contact lens wearers are at the mercy of a bug that is found in tap water and gnaws through the eyeballs causing blindness, scientists have warned.” The single-celled parasite Acanthamoeba, which is found in tap water, “feeds on bacteria found on dirty contact lenses and cases.” When contaminated lenses are inserted into the eye, the parasite “starts to eat its way through the cornea, the outer layer of the eyeball and breeding as it goes,” potentially damaging vision permanently. Keeping contact lenses clean, not using water to rinse them off, replacing contact lens cases regularly, and not wearing lenses in the shower or in the swimming pool will help reduce the risk of Acanthamoeba infections.
Eye Exams May Find Signs Of Illness Elsewhere In The Body.
The Pocono (PA) Record (8/30, Leap) reported that during eye examinations, optometrists not only can detect vision problems, but also can find signs of illness elsewhere in the body, such as diabetes, which may lead to “diabetic retinopathy, which damages vision, according to the American Optometric Association. ” During the course of a dilated eye exam conducted on a patient complaining of double vision, Stroudsburg, PA optometrist Stephen Rudnick, OD, found swelling of the optic nerve. “The patient was then further evaluated and she was diagnosed with advanced Lyme disease that had progressed into meningitis, causing the brain to swell.” The patient was hospitalized and is now recovering well.
OSHA Ranks Computer Vision IssuesNo. 1 Health-Related Office Complaint.
In an entry for the Huffington Post (7/5) blog, optometrist Robert Joyce, OD, discussed computer vision syndrome, a workplace ergonomic issue that “is by far and away the most prevalent, affecting an estimated 150 to 200 million Americans, or 90 percent of computer users who work more than three hours a day on the computer.” Notably, “computer vision issues are ranked by OSHA No. 1 on the list of health-related office complaints. The National Eye Institute, again unsurprisingly, recently released data showing a 66 percent increase in the prevalence of myopia in the 25 years since the advent of the personal computer.” The rest of the entry was devoted to steps people can take to lessen eyestrain while working on the computer. Dr. Joyce also advised readers to see an eye care professional annually for a thorough check-up.
NIOSH: Many Computer Users Have Symptoms Of Computer Vision Syndrome.
The Sacramento (CA) Bee (8/5, 1D, Gonzales) reported, “Eye trouble associated with sitting in front of a computer is a national phenomenon, with computer users going to eye doctors with complaints of tired, dry or weepy eyes, headaches, blurry vision and eyestrain.” In fact, “the National Institute of Occupational Safety and Health estimates that 90 percent of people who spend three hours or more a day in front of a computer screen have some symptoms of computer vision syndrome.” In addition, according to the National Eye Institute, “kids are being diagnosed with myopia, or nearsightedness, more often and at an earlier age because of long stints in front of the screens.” At Vision Care Consultants, our doctors can now fit you with glasses specifically designed to relieve computer vision syndrome.
Acne Drug Associated With Increased Eye-Infection Risk.
HealthDay (6/1, Goodwin) reports, “Teens who take the acne medication commonly known as Accutane (isotretinoin) appear to face twice the risk of eye infections, including conjunctivitis (pink eye) and styes,” according to a study published in the Archives of Dermatology. For the study, investigators “collected data on nearly 15,000 teens and young adults taking isotretinoin to treat acne and compared their rates of eye infections to an age- and gender-matched group that had acne but was not taking the drugs, and to a third group that didn’t take the drugs and didn’t have acne.” They found that “compared to the acne-free group, those taking isotretinoin were at 70 percent increased risk of an eye infection over the course of a year.”
Blue Light Exposure May Contribute To Macular Degeneration.
The Milwaukee Journal Sentinel /ARA (5/25) reports that “low macular pigment is a key risk for age-related macular degeneration (AMD), which destroys central vision, and is the leading cause of vision loss in people over age 50, according to the American Optometric Association. Science indicates that damage from blue light exposure is a significant contributing factor to AMD.” The article advises readers to visit their “eye care professional and ask about having…MPOD (macular pigment optical density) measured — it’s simple, affordable and takes only a few minutes.” As a leader in the eyecare field, Vision Care Consultants has been providing the MPOD testing technology to our patients for over 5 years.
AMD Associated With Stroke Risk.
MedPage Today (4/28, Neale) reported, “Patients with age-related macular degeneration (AMD) appear to be at risk for both ischemic and hemorrhagic stroke,” according to a study published online April 24 in Stroke: Journal of the American Heart Association. “Through an average follow-up of 13 years, middle-age individuals with the eye condition had a higher rate of any stroke (7.6% versus 4.9%),” researchers reported. “The difference was consistent for both ischemic stroke (6.4% versus 4.4%) and intracerebral hemorrhage (1.2% versus 0.4%).”
Isotretinoin Use Associated With Adverse Ocular Events.
MedWire (4/27, Albert) reports, “Use of isotretinoin for treatment of acne may result in an increased risk for adverse ocular events such as conjunctivitis,” according to a study published online in the Archives of Dermatology. After examining data on “14,682 adolescents and young people (mean age 16.55 years) who were prescribed isotretinoin for treatment of acne” and comparing them to a similarly matched group of young people being treated for acne without isotretinoin and another without acne at all, then following everyone for one year, researchers found that “13.8% of the isotretinoin group experienced adverse ocular events in total, compared with 9.6% of the isotretinoin-naive and 7.1% of the acne-free groups,” and that the “conjunctivitis, hordeolum, chalazion, and blepharitis” were the most common adverse ocular effects experienced.
Early Glaucoma Detection Key To Maintaining Vision.
HealthDay (4/21, Gordon) reported, “Glaucoma isn’t just one disease but a group of conditions that cause damage to the optic nerve, which connects the eye to the brain.” Unfortunately, when “left untreated, glaucoma can in fact cause blindness. And because the disease can progress for long periods undetected, experts stress that checkups and early detection are key to maintaining vision.” Once lost, vision cannot be restored, according to experts.
Eye Symptoms May Be Due To Other Conditions.
The UK’s Daily Mail (3/14, Epstein) reports on various “potential causes of…eye symptoms.” For instance, “persistent red blotches on the whites of both eyes can be a sign of hypertension,” while dry eyes can be caused by menopause causing “changes in hormone levels, affecting, among other things, the lubrication mechanisms of the eye.”
Genes Predicting Macular Degeneration Identified.
HealthDay (2/25, Dallas) reported that scientists have “identified more than 50 genes that can predict age-related macular degeneration (AMD), one of the leading causes of blindness worldwide,” according to research published in the journal Genome Medicine. After using “a human donor-eye repository to identify differences in gene expression in people with AMD and those with normal eyes,” researchers “found that genes expressed below and in the retina, thought to be involved in inflammatory and immune response and wound healing, were overexpressed in eyes with AMD. Here at Vision Care Consultants, our doctors were one of the first practices in the nation to perform the “Macula Protect” genetic testing for our patients. Call our office today to find out if genetic testing is appropriate for you.
AOA: AMD Leading Cause Of Severe Vision Loss In Older Americans.
The Milwaukee Journal Sentinel /ARA (2/8) reports that age-related macular degeneration (AMD) “is the leading cause of severe vision loss in Americans over age 50, according to the American Optometric Association.” Currently, “the Centers for Disease Control and Prevention (CDC) estimate 1.8 million have AMD and another 7.3 million people are at risk. As our population ages at an ever-increasing rate, the incidence of AMD is expected to triple by 2025.” The article goes on to explain how people develop AMD, what factors may affect central vision, such as “harmful blue light from the sun, indoor lighting, and even computers, along with poor diet, smoking, and high body mass index.”
Next-Generation Contact Lenses May Help Monitor Health.
On its website, KDKA-TV Pittsburgh (1/12) reported that next-generation contact lenses, “called ‘smart lenses’…are packed with circuits, sensors and wireless technology — all designed to keep an eye on your health.” Researchers are now testing contact lenses that may someday “replace the standard blood test,” pointing out that “biomarkers found in the blood — such as cholesterol, sodium, potassium and glucose — can also be found on the surface of the eye.” Currently, one type of smart contact lens already out on the market in Europe monitors eye pressure over the course of a day. Called the Trigger Fish, it can diagnose glaucoma. Contact lenses still in the developmental stage may one day slowly release eye medication over a long period of time.
Protective Eye Gear Reduces Eye Injuries In US Female Lacrosse Players.
Reuters (12/17, Grens) reported that in young women playing lacrosse appear to have far fewer eye injuries since wearing eye protection mandated by US Lacrosse since 2004, according to a study published online Dec. 8 in the American Journal of Sports Medicine. During the years 2002 to 2003, 22 eye injuries were experienced by female players. Following the protective eye wear requirement of 2004, however, only five injuries occurred between 2004 and 2009. Notably, of those cases, one involved inflammation and the other four injuries were because the young women had failed to wear protective eye gear
Expert Provides Tips On Minimizing Risks From Night Driving.
The Chicago Tribune (11/29, Stevens) reports that “driving in the dark poses very real dangers to your physical well-being, particularly if your daytime vision is less than 20/20.” Cristina Schnider, senior director of medical affairs with Johnson and Johnson vision care, provided “some tips on minimizing the risk,” such as making sure that “daytime distance correction is well adjusted for your eyes” and making sure that astigmatism is properly corrected. Making sure that eyeglasses have anti-reflection coating will cut down on nighttime glare. Motorists driving at night should be mindful that their reaction times are slower and that the eye processes images differently in darkness. Therefore, it’s important to “slow down,” and “minimize multi-tasking,” Schnider advised.
New Laser Treatment Changes Eye Color.
BBC News (11/5) reported that a new laser treatment pioneered in the US by Stroma Medical may change a “patient’s eye colour. Dr Gregg Homer claims 20 seconds of laser light can remove pigment in brown eyes so they gradually turn blue. He is now seeking up to $750,000 (£468,000) of investment to continue clinical trials.” A computer scan maps the iris. The laser then “agitates the pigment on the surface of the iris” several times over the course of 20 seconds. About three weeks later, the eyes turn blue. Eye experts “urge caution,” however, “because destroying eye pigment can cause sight problems if too much light is allowed to enter the pupil.”
Physically Active Lifestyle May Reduce Glaucoma Risk.
HealthDay (10/31, Preidt) reports that according to a study published in the October issue of the journal Investigative Ophthalmology & Visual Science, “a physically active lifestyle may help protect your eyes from glaucoma.” After examining “the association between physical activity and eye pressure in 5,650 men and women aged 48 to 90 in Britain,” researchers “found that moderate physical exercise performed about 15 years previously was associated with a 25 percent reduced risk of low ocular perfusion pressure (OPP), an important risk factor for glaucoma.”
FDA Warns Against Decorative Contact Lenses Without A Prescription.
KCRG-TV Cedar Rapids (10/26, Yeung) reports, “Dr. Rachel Bishop from the National Eye Institute says that people should not get decorative contacts until they’ve seen an eye specialist, gotten a prescription, and learned how to care for them.” Otherwise, “taking shortcuts and buying these without getting an eye exam” could put “a person at significant risk,” ranging from “irritated eyes to permanent vision loss.” The FDA said “even decorative lenses are prescription, so over-the-counter sales are illegal.” The Star-Ledger (10/26, Baxter) reports the FDA has “received reports of the lenses causing corneal ulcers, eye infections and vision loss because of people not using them properly, or because they were not designed properly for someone’s eyes,” according to the FDA.
Car Windows Do Not Filter Out UVA Rays.
The Boston Globe (10/13, DeMarco) reports, “Car windows — and those in your home — are good at filtering out ultraviolet B rays, which cause sunburns. But car and home windows generally don’t filter out ultraviolet A rays, which penetrate deeper into the skin” and “can interfere with your body’s ability to protect against skin cancer,” explained dermatologist Paul Lizzul, MD, PhD, MPH, MBA, associate director of clinical research in dermatology at Tufts Medical Center. According to the American Academy of Dermatology’s website , sunscreen should be worn “on exposed areas whenever we go outside,” and that includes inside the car. Quality sunglasses that block UVA, UVB & UVC should also be worn outside and inside the car to protect the eyes from the harmful effects of ultraviolet rays. If you are not sure if your sunglasses provide all that protection just bring them in to Vision Care Consultants optical. Our experienced opticians will check them in our UV scanner and let you know how your glasses perform.
New Study On Texting And Driving Released.
Reuters (10/6, Forsyth) reports that Texas A&M’s Texas Transportation Institute released a study yesterday finding that using a cell phone while operating vehicles doubles a driver’s reaction time. The longer reaction time means drivers have less time to focus on the road and react to changing conditions. The study tested 42 drivers between 16 and 54 who sent and received text messages while driving on an 11-mile text rack. When not texting, a driver took one to two seconds to respond to a flashing light. However, a texting driver took three to four seconds, making them 11 times more likely to drive through the flashing light. This is the first study conducted on actual vehicles, not simulators. US DOT statistics show that about 20% of fatal accidents are due to texting and driving.
A Third Of All Prescription Glasses Wearers Regularly Use Two Pairs.
USA Today (9/15, Healy) reports, “A third of all prescription eyeglass wearers regularly use two or more pairs, sometimes just to have different frames for different fashions.” What’s more, “about 16 million Americans who don’t even need prescription glasses still wear eyeglasses to be fashionable, according to Kristie Whitford, fashion spokesperson for the trade group The Vision Council.” The article goes on to detail the latest eyewear fashions for the fall, including “vintage revivals” and “Geek chic.”
NRC Considering Radiation Dose Limit Change To Lens Of The Eye.
On its website, the trade outlet Occupational Health & Safety (9/2) reports that the Nuclear Regulatory Commission (NRC) “has asked for comments from stakeholders about possibly lowering the current US occupational exposure limit for radiation to the lens of the eye. NRC hasn’t begun rulemaking on the issue, but its notices said the international radiation protection community may follow the International Commission on Radiological Protection’s recent recommended limit of 20 mSv (2 rem) per year, averaged over defined periods of five years, with no single year exceeding 50 mSv (5 rem).” Currently, the US limit is “seven times higher: 150 mSv (15 rem) per year.”
Optometrists Remind Parents To Get Children Back-To-School Eye Exams.
OzarksFirst (8/10) reports in a brief story, “Optometrists remind parents to add an eye exam to your child’s back to school checklist.” OzarksFirst notes, “The American Opto metric Association says healthy eyes at the start of the school year can help avoid some learning difficulties in class.” The article also includes some advice from AOA’s James Sheedy, OD, about the importance of giving one’s eyes a chance to rest when spending long amounts of time in front of the computer. “Every twenty minutes you look away for twenty feet for twenty seconds and this gives the eyes a chance to relax,” Sheedy said. Here at Vision Care Consultants our pediatric specialist Dr. Marie Wehner makes certain every child in our practice has healthy, effective vision with all the tools necessary for them to succeed academically.
AOA Report Explains Optimal Uses Of 3D Technology In Classrooms.
Modern Medicine (8/10) reports, “In an effort to assess and address the vision-related effects of the increased use of technology in learning environments, the American Optometric Association (AOA) has conducted a survey and released a report.” AOA expert James Sheedy, OD, PhD, said, “Today’s classroom technology is extremely visual, making it critical for students to maintain excellent eye health … Binocular vision, focusing abilities, as well as nearsightedness and farsightedness should be checked by an eye doctor yearly, particularly as students head back to school.” AOA has also “developed a new report, ‘ 3D in the Classroom–An AOA Report ,’ in collaboration with educators, vision researchers, and 3D industry experts, to explain the optimal uses of 3D technology in the classroom to teachers, students, and parents.”
Several Nutrients May Decrease Risk For Macular Degeneration.
The Time (6/20, Melnick) “Healthland” blog reported that, according to a study published in the June issue of the Archives of Ophthalmology, “people who got the highest amounts of several nutrients, including zinc and omega-3 fatty acids, in their diet had a lower risk of developing a condition known as macular degeneration.” For the study, investigators examined “2,167 people over age 55 who had one of the two genes known to contribute to macular degeneration,” surveyed eating habits, then followed the group for 10 years. “The researchers found that among those with the CFH gene variation, people who got the most zinc, beta carotene, omega-3 fatty acids or lutein/zeaxanthin in their diets were less likely to develop macular degeneration than those who got the lowest amounts.” Here at Vision Care Consultants our doctors prescribe the eye vitamins containing all the above mentioned nutrients for our patients who need them.
One In Three Adults Unaware Of Eye Health RisksOf Too Much Sun Exposure.
USA Today (6/9, Healy) reports that wearing a hat and protecting eyes “from harmful UV rays” is as much a part of sun protection as slathering on sunscreen. “A 2009 survey by the American Optometric Association found that one in three adults are unaware of the eye health risks of spending too much time in the sun without proper protection.” Excessive UV exposure may result in pterygium, macular degeneration, or cataracts. And, “even a few hours of intense, unprotected exposure can have consequences, says optometrist Sarah Hinkley of the American Optometric Association,” possibly leading to painful photokeratitis.
Zeaxanthin, Lutein Helps Protect Eyes Against UV Light Damage.
The Calgary Herald /Monterey County Herald (5/26, Quinn) reported that, according to the National Eye Institute, eyesight is “all about light” entering the eye and hitting the retina. That body “contains ‘photoreceptors’ that convert light to electrical signals that travel to the brain and figure out what we ‘see.'” Unfortunately, ultraviolet (UV) light may damage eyes, much like it does skin. Fortunately, “specific nutrients and other substances in foods can help to absorb dangerous light and act as a shield.” The article went on to explain that vegetables and fruits containing zeaxanthin and lutein may help protect the eye against damage caused by ultraviolet light. Here at Vision Care Consultants we have advanced instrumentation that measures the actual amounts of these protective pigments in your eyes. If we find your pigment levels too low our doctors can prescribe for you the corrected supplement to replace those protective pigments back safe levels before retinal damage occurs.
Physician Makes Case For Lifestyle Changes To Slow Coming Tide Of Type 2 Diabetes Cases.
In a guest column in the Des Moines Register (5/24), Dr. Robert S. Bar, of the University of Iowa College of Medicine, wrote, “Unless Americans drastically change their dietary and exercise habits, diabetes may play a major role in nearly 90 percent of all patients seen by US physicians in the next five to 10 years.” Of special concern is “a larger, poorly defined group of people that arguably could double or triple the current number of people with diabetes,” that is, those who have been “described by physicians as having ‘borderline diabetes’ or ‘pre-diabetes.'” Bar made the case for lifestyle changes to slow the coming tide of type 2 diabetes patients, such as exercise, losing weight, cutting out junk foods, and being aware of family history. Here at Vision Care Consultants we do comprehensive eye exams to detect even the earliest effects of diabetes could have on your eyes.
AOA, Vision Council To Release Report On Safety Of Buying Prescription Eyeglasses Online.
Consumers increasingly feel more comfortable buying eyeglasses from online vendors. While buying online is convenient and cost-effective, consumers may not end up with the prescription they need. In fact, optometrist Sam Pierce, OD, “a board member of the American Optometric Association, which represents 36,000 doctors of optometry, says preliminary research has revealed some eyewear prescriptions are not being filled accurately online.” Because of that, the AOA “and the Vision Council plan to release a joint report this summer examining the safety of buying prescription glasses on the Web.”
Heavy Precipitation Prompted This Year’s Particularly Robust Allergy Season.
The AP (5/16) reports, “Warnings about the difficult season have come from allergy specialists from New York to Atlanta, Chicago to California.” Heavy snow and rain in “some parts of the country have nourished a profusion of tree pollen, while a sudden shift to warm, sunny weather has made its release more robust.” The deluges and some flooding have also boosted the “volume on mold.”
New 3-D Video Games May Be a Problem For Some Individuals
25th February, 2011 – Posted by Dr. David Seibel – No CommentsExtended exposure to 3-D media input especially for certain individuals may have potential vision risksComing soon to an electronics store near you will be a series of new 3-D video games! The thought is exciting to many. Greater reality in imaging, a more intense gaming experience. But will this have eye and vision implications? Well, generally for most people the answer will be no. At most these 3-D games, just like 3-D movies and television can result in some eye strain or headaches after prolonged viewing. There is no credible scientific evidence that viewing 3-D media causes any perminent eye or vision problems. Some individuals (especially young children) who have a binocular vision condition called “esophoria” where the eyes tend to focus or align closer in space than the object they are looking at may be at greater risk for problems. Theoretically the stress of over-convergence associated with 3-D media could stimulate progression in myopia (nearsightedness) development in these “at risk” individuals. However this is only a theoretical possibility and not supported by evidenced based research at this point in time.
Sunglasses Necessary To Prevent Eyes From UV Damage.
The Washington Post (7/4, Butler) reported that wearing sunglasses is necessary to protect the eyes from damage from ultraviolet (UV) rays. Optometrist Michael Rosenblatt, OD, pointed out that “certain people run an elevated risk for UV damage,” particularly people “with light-colored irises.” He explained, “If you easily burn in the sun, you should think of yourself as a person who suffers greater damage from UV light in all areas, including your eyes.” For that reason, he recommended sunglasses that “extend from the eyebrow to the cheek and wrap around the contour of face, along with lenses that have 100 percent UVA and UVB protection. At Vision Care Consultants our opticians can verify your current sunglasses to make sure they provide the full spectrum of UV protection.
Eye Experts Say Protective Eyewear Would Prevent Most Sports-Related Eye Injuries.
The Pittsburgh Post-Gazette (7/18, Kelly) reports, “More than 600,000 Americans will suffer an eye injury while playing a sport this year,” according to the National Eye Institute (NEI). “Of these, about 42,000 will be serious enough to require treatment in a hospital emergency room.” But, “more than 90 percent of these injuries could be prevented if the athletes were wearing protective eyewear, say the NEI and the national associations of ophthalmologists and optometrists.” Regular eyeglasses are no substitute for impact-resistant polycarbonate lenses. Ideally, the glasses should completely cover the eye socket, particularly for those who play basket ball and racket ball.
