When a prime-time sportscaster went on the air to cover the Sochi 2014 Winter Olympics with pink eye, the world took notice. One UAB optometrist says this virus currently lacks an FDA-approved drug, but she has a planned study to solve that.
A series of coincidences and a collaboration with researchers at the University of Iowa and Columbia University gave Michael Stone, Ironman triathlete, fundraiser, advocate, and author, answers about the retinal condition that has left him legally blind.
Minimizing a person’s sight for as little as a week may help improve the brain’s ability to process hearing.
Deprivation of vision during critical periods of childhood development has long been thought to result in irreversible vision loss. Now, researchers from the Schepens Eye Research Institute/Massachusetts Eye and Ear, Harvard Medical School (HMS) and Massachusetts Institute of Technology (MIT) have challenged that theory by studying a unique population of pediatric patients who were blind during these critical periods before removal of bilateral cataracts. The researchers found improvement after sight onset in contrast sensitivity tests, which measure basic visual function and have well-understood neural underpinnings. Their results show that the human visual system can retain plasticity beyond critical periods, even after early and extended blindness.
Using a novel high-throughput screening process, scientists have for the first time identified molecules with the potential to block the accumulation of a toxic eye protein that can lead to early onset of glaucoma.
Using a simple study of eye movements, Johns Hopkins scientists report evidence that people who are less patient tend to move their eyes with greater speed. The findings, the researchers say, suggest that the weight people give to the passage of time may be a trait consistently used throughout their brains, affecting the speed with which they make movements, as well as the way they make certain decisions.
A comparative long-range study by Mayo Clinic ophthalmology researchers shows that the probability of blindness from glaucoma 20 years after diagnosis has dropped by half in the last generation. The findings appear online in the “in press” section of the journal Ophthalmology.
The probability of blindness due to the serious eye disease glaucoma has decreased by nearly half since 1980, according to a study published this month in Ophthalmology, the journal of the American Academy of Ophthalmology. The researchers speculate that advances in diagnosis and therapy are likely causes for the decrease, but caution that a significant proportion of patients still progress to blindness.
Glaucoma is a stealthy disease. It can cause irreparable damage to the eyes before there is any vision loss. It also has been known since antiquity, but its cause is a mystery in most cases. Glaucoma Awareness Month is a good time to ask: Are researchers making progress toward solving this mystery?
Aging gracefully may not be an option for the 40 million people worldwide who are blind or have significant visual impairment. It’s reported that 65% of those with visual impairment and 82% of those who are blind are over 50 years of age. In a special issue of Investigative Ophthalmology & Visual Science (IOVS), ophthalmic leaders from around the world address “the aging eye” to focus attention on unmet needs and accelerate the translation of research findings into effective clinical care.
Investigators at the Cedars-Sinai Regenerative Medicine Institute have identified new molecular abnormalities in the diabetic cornea that could contribute to eye problems in affected patients. With this new knowledge, investigators aim to accelerate the process of healing and repair in damaged corneas to ultimately reverse the effects of diabetes-induced eye complications.
Small research labs provide an engine of discovery for new therapies. But developing a new drug or device requires expertise that is typically beyond the scope of a single lab. NEI has a program that helps diverse experts work together and move potential therapies into clinical trials.
Baseball players at bat follow coaches' advice to "keep your eye on the ball"—but head movements play a surprisingly important role in tracking pitches, suggests a study in Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Researchers from the Massachusetts Eye and Ear, Harvard Vanguard Medical Associates and Harvard Medical School Department of Ophthalmology report on the first study in 35 years that reviews the circumstances around retinal detachment after open globe injuries (OGI) and describes a new tool that may help ophthalmologists predict which patients are at higher risk after open globe trauma so they can potentially prevent retinal detachment from happening or identify – and repair – it more quickly, thus saving vision.
For the estimated 10 percent of patients whose bodies reject a corneal transplant, the odds of a second transplant succeeding are poor. All that could change, however, based on a UT Southwestern Medical Center study that has found a way to boost the corneal transplant acceptance rate.
Preoperative consultations before cataract surgery became more common for Medicare patients despite no clear guidelines about when to require such a service, hinting at unnecessary use of health care resources, according to a study published by JAMA Internal Medicine, a JAMA Network publication.

Researchers from the Schepens Eye Research Institute/Massachusetts Eye and Ear and Harvard Medical School have just identified a potential therapy.
Despite recent advances in prevention and treatment of most vision loss attributed to diabetes, a new study shows that fewer than half of Americans with damage to their eyes from diabetes are aware of the link between the disease and visual impairment, and only six in 10 had their eyes fully examined in the year leading up to the study.
Dr. JP Lowery is one of hundreds of optometrists across the country who provide free comprehensive eye exams to infants as part of a nationwide program. The exams can detect eye problems early enough to prevent vision loss and learning disabilities.
Shun-Nan Yang is also an expert in eye movement control as it relates to reading and sports performance.
Holiday travelers will be relieved to know that security threats are rarely encountered at airport checkpoints. But according to a new study published in the Journal of Vision, the low frequency at which trained airport screeners find threats reduces the chances targets will be found.
Researchers at Massachusetts Eye and Ear/Harvard Medical School Department of Ophthalmology, Boston Children’s Hospital, and the Massachusetts Institute of Technology are one step closer to an eye drop-free reality with the development of a drug-eluting contact lens designed for prolonged delivery of latanoprost, a common drug used for the treatment of glaucoma, the leading cause of irreversible blindness worldwide.
Exposure for even fractions of a second to high-powered blue handheld laser devices can cause serious eye injuries, according to a study recently released online in Ophthalmology, the journal of the American Academy of Ophthalmology. The researchers have concluded that the wide availability of these devices, which are often marketed as toys, could lead to an epidemic of ocular injuries, and greater public awareness and government intervention should be encouraged.
Adding to evidence that "high-volume" specialty care in busy teaching hospitals leads to efficiencies unavailable in community hospitals, a new study by Johns Hopkins researchers finds that patients undergoing repair of traumatic eye socket injuries at its busy academic medical center fared just as well at far less cost than those treated at all other Maryland hospitals.
Researchers in the Cedars-Sinai Regenerative Medicine Institute have designed and tested a novel, minute-long procedure to prepare human amniotic membrane for use as a scaffold for specialized stem cells that may be used to treat some corneal diseases. This membrane serves as a foundation that supports the growth of stem cells in order to graft them onto the cornea. This new method, explained in a paper published this month in the journal PLOS ONE, may accelerate research and clinical applications for stem cell corneal transplantation.
Follow-up in older adults shows a high rate of anisometropia, or differing levels of visual abnormalities between eyes, reports a study in Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Research presented today, at the 117th Annual Meeting of the American Academy of Ophthalmology in New Orleans, has found that women who have taken oral contraceptives for three or more years are twice as likely to suffer from glaucoma, one of the leading causes of blindness which affects nearly 60 million worldwide. The researchers caution gynecologists and ophthalmologists to be aware of the fact that oral contraceptives might play a role in glaucomatous diseases, and inform patients to have their eyes screened for glaucoma if they also have other risk factors.
The American Academy of Ophthalmology today unveiled the nation’s first comprehensive eye disease and condition patient database. The IRIS ™ Registry (Intelligent Research in Sight) made its debut in a presentation to 25,000 attendees during the opening session of the world’s largest ophthalmic conference – the 117th Annual Meeting of the American Academy of Ophthalmology at the Ernest N. Morial Convention Center in New Orleans.
Residents of major cities with high levels of air pollution have an increased risk of dry eye syndrome, according to a study presented at the world's largest ophthalmic conference, the 117th Annual Meeting of the American Academy of Ophthalmology, in New Orleans. Study subjects in and around Chicago and New York City were found to be three to four times more likely to be diagnosed with dry eye syndrome compared to less urban areas with relatively little air pollution.
Research presented today at the 117th Annual Meeting of the American Academy of Ophthalmology shows that wearing visors in the National Hockey League (NHL) could cause a four-fold decrease in the risk of eye injuries. Furthermore, the study found that eye injuries over the last 10 seasons have cost the NHL and its associated franchises more than $32 million in missed games.
Research presented today at the 117th Annual Meeting of the American Academy of Ophthalmology shows promising data about a device that helps people who have lost their vision due to a blinding genetic disease to recognize common objects. In the study, the researchers found when the objects’ outlines had been enhanced, there was increased recognition. The device, called the Argus II, is the first FDA-approved retinal implant for adults with retinitis pigmentosa.
Ten years after a transplant, a cornea from a 71-year-old donor is likely to remain as healthy as a cornea from a donor half that age, according to a study funded by the National Institutes of Health. Corneas from donors over age 71 perform slightly less well, but still remain healthy for the majority of transplant recipients after 10 years, the study found.
Cataract surgeries performed over one year eventually save $123.4 billion over 13 years and delivers a 4,567 percent financial return on investment to society according to the results of a cost-utility study, published online today in the Academy’s official journal, Ophthalmology, and will be presented on Nov. 17 at the world’s largest ophthalmic conference, the American Academy of Ophthalmology’s 117th Annual Meeting, in New Orleans. Researchers say that the results prove that healthcare interventions create substantial economic wealth.
A multi-center study (NCT00494676) led by Alex Bowers, Ph.D., Assistant Professor of Ophthalmology at HMS and Assistant Scientist at Massachusetts Eye and Ear/Schepens Eye Research Institute, determined that real peripheral prism glasses are more helpful than sham peripheral prism glasses for patients with hemianopia during every day walking.

It’s almost time to don your outfit for the 31st, but keep in mind some important safety tips, say doctors at Philadelphia’s Wills Eye Hospital, that may keep you from doing real harm to your eyes -potentially landing yourself in the emergency room and in some cases, risking permanent vision loss.
New research on myopia—how it develops, risk and protective factors, and potentially effective measures for prevention and treatment are reported across twenty articles in the November issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Some of the most common vision disorders take their toll by damaging blood vessels near the retina. But it’s difficult for eye care professionals and researchers to see these vessels with standard techniques. NIH’s National Eye Institute is supporting the development of new methods to get deeper, more detailed views of the retinal vasculature.
If your Halloween costume includes changing your eye color, think twice before wearing cosmetic contact lenses.
Just 13 days in space may be enough to cause profound changes in eye structure and gene expression, report researchers. Their study is the first to examine eye-related gene expression and cell behavior after spaceflight.
A promising technique for treating human eye disease has proven effective in preclinical studies and may lead to new treatments to prevent blindness, according to experiments conducted at The Scripps Research Institute. The studies involved controlling the actions of microRNAs.
Contact lens discomfort may be the leading cause of patient dissatisfaction with, and discontinuation of, contact lens wear throughout the world — but there is little agreement among vision researchers and eye care professionals about how to define and manage its causes. T the Tear Film & Ocular Surface Society organized the TFOS International Workshop on Contact Lens Discomfort and findings were reported Friday in the current issue of journal Investigative Ophthalmology & Visual Science (www.iovs.org).
A team of University of Washington computer scientists has created a software program that watches a user's movements and gives spoken feedback on what to change to accurately complete a yoga pose. Researchers hope this will allow people who are blind or low-vision to participate more fully in yoga exercises.
Tufts University researchers have identified a possible topical treatment for age-related macular degeneration (AMD). The findings are the first to report successful topical use of a compound with the potential to treat both major forms of AMD, which can currently only be treated in later stages with regular injections into the eye.
