Three young adults who received gene therapy for a blinding eye condition remained healthy and maintained previous visual gains one year later, according to an August online report in Human Gene Therapy. One patient also noticed a visual improvement that helped her perform daily tasks, which scientists describe in an Aug. 13 letter to the editor in the New England Journal of Medicine.These findings have emerged from a phase I clinical trial supported by the National Eye Institute (NEI) at the...

 Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University.The researchers calculated intakes of docosahexaenoic acid (DHA) and eicosapentaenoic...

Researchers are studying the use of a NASA device that can be to test whether a cataract is developing before a patient's vision begins to cloud over. The noninvasive test can determine if the eyes are losing the natural compound that keeps cataracts, a condition where the eye's normally clear lens becomes permanently clouded, at bay.   Cataracts are currently the world's leading cause of vision loss, and surgery to replace the lens is the only fix. Interestingly, the device also...

U.S. eye doctors collaborated with the National Aeronautics and Space Administration to detect pre-cataract protein changes. Researchers from NASA, the John H. Glenn Research Center in Cleveland and the National Eye Institute in Bethesda, Md., conducted the clinical trial of the device developed to analyze the growth of protein crystals in a zero-gravity space environment. The study, published in the Archives of Ophthalmology, looked at 380 eyes of people between the ages of 7-86 and found...

A compact fiber-optic probe developed for the space program has now proven valuable for patients in the clinic as the first non-invasive early detection device for cataracts, the leading cause of vision loss worldwide. Researchers from the National Eye Institute (NEI), part of the National Institutes of Health, and the National Aeronautics and Space Administration (NASA) collaborated to develop a simple, safe eye test for measuring a protein related to cataract formation. If subtle protein...

Researchers said on Tuesday that stem cells from tiny embryos can be used to restore lost hearing and vision in animals, in what they believe is a first step toward helping people. A team of researchers repaired hearing in guinea pigs using human bone marrow stem cells, while another group grew functioning eyes in tadpoles using frog cells. Both teams said their findings help describe some of the most basic biological processes underlying the development of hearing and sight, and may help in...

By Kevin Freking Associated Press What does a company do when there's anecdotal evidence that two of its drugs are equally effective in treating a leading cause of blindness in the elderly, one costing patients $60 per treatment and the other $2,000? In the case of Genentech Inc., nothing. The company declined to seek federal approval for the cheaper drug, Avastin, to treat the wet form of age-related macular degeneration. Nor would it help finance -- or cooperate with -- a National Eye...

Researchers at the National Eye Institute, part of the U.S. National Institutes of Health, reported Monday that 50 percent of Americans have some sort of vision problem, a number that far exceeds previous estimates. The most common vision problems were myopia or astigmatism, which causes fuzzy vision, the researchers said. "Clinically important refractive error affects half of the U.S. population 20 years or older," Susan Vitale and colleagues wrote in a report about the study. Vitale and...

Diabetic retinopathy has been found in nearly 8 percent of pre-diabetic participants in the Diabetes Prevention Program (DPP), according to a report presented today at the American Diabetes Association's 65th Annual Scientific Sessions. Diabetic retinopathy, which can lead to vision loss, was also seen in 12 percent of participants with type 2 diabetes who developed diabetes during the DPP. No other long-term study has evaluated retinopathy in a population so carefully examined for the...
