  1. Study suggests photochemical retinal exposure limits should differ during surgery

    Study suggests photochemical retinal exposure limits should differ during surgery Fort Lauderdale, Fla. "” A recent study revealed that previously developed photochemical retinal exposure limits are not applicable for ophthalmic instrument exposure, specifically for the eye anesthetized during surgical procedures. The research evaluated whether or not recently published retinal injury thresholds call for revisions to current light safety guidelines for human retinal exposure. The study, being p

  2. Age-related macular degeneration linked to new gene

    Age-related macular degeneration linked to new gene Fort Lauderdale, Fla. "” In an analysis of the genes of more than 1,000 patients with age-related macular degeneration (AMD), an international team of scientists discovered a strong association between the vision problem and the presence of a new gene. The researchers are presenting their findings this week at the 2010 Annual Meeting of the Association for Research in Vision and Ophthalmology. The new gene connection is with hepatic lipase gen

  3. Researchers develop method to deliver protein drugs though disposable contact lenses

    Researchers develop method to deliver protein drugs though disposable contact lenses New technique may eliminate inefficiency and side effects of eye drops Fort Lauderdale, Fla. "” A new technique that delivers protein drugs via disposable contact lenses may eliminate the inefficiency and side effects of eye drops, according to the abstract of a poster presentation at the 2010 Annual Meeting of the Association for Research in Vision and Ophthalmology this week. Researchers from the University o

  4. Low-cost camera can screen diabetics for eye damage in primary care physician's office

    Low-cost camera can screen diabetics for eye damage in primary care physician's office New device could make screening for diabetic retinopathy affordable, convenient Fort Lauderdale, Fla. "” By adding an optical attachment to a Canon consumer digital camera, researchers have developed an easy-to-use device that takes high-quality pictures of the fundus to screen diabetics for diabetic retinopathy, a degeneration of the retina that is one of the leading causes of new cases of blindness. Accordi

  5. Gene therapy clinical trial shows patient profiles may be an opportunity for intervention

    Gene therapy clinical trial shows patient profiles may be an opportunity for intervention Fort Lauderdale, Fla. - The Leber Hereditary Optic Neuropathy (LHON) Gene Therapy Clinical Trial aims to identify affected patients and carriers with mtDNA G11778A mutation in order to deliver copies of normal nuclear-encoded ND4 gene into the nuclei of retinal ganglion cells (RGC). After the preparatory phase, the researchers concluded that "RGC survival with dysfunction many months after visual loss may

  6. Study shows omega 3 intake inversely related to severity of age-related macular degeneration

    Study shows omega 3 intake inversely related to severity of age-related macular degeneration Fort Lauderdale, Fla. "” An examination of more than 4,200 seniors revealed a correlation between the consumption of omega 3 nutrients and the severity of age-related macular degeneration (AMD), according to a presentation at the 2010 Annual Meeting of the Association for Research in Vision and Ophthalmology this week. The researchers from the National Eye Institute set out to review the demographics an

  7. Migraine Sufferers: More Difficulty Tuning Out Visual Stimuli?

    Migraine Sufferers: More Difficulty Tuning Out Visual Stimuli? Rockville, Md. - When people feel the onset of a migraine headache, they may head to a dark, quiet room to rest. This instinct may be sound: A new study suggests that even without the headache, migraine sufferers may process visual cues better in an environment with few visual distractions. In a study published in the April issue of Investigative Ophthalmology and Visual Science ("Visual Noise Selectively Degrades Vision in Migraine

  8. Researchers aim for consensus on measuring the impact of visual impairment

    Researchers aim for consensus on measuring the impact of visual impairment Rockville, MD - New guidelines that outline best practices for measuring the economic burden of visual impairment will make it easier for the policy, science and medical communities to draw conclusions and compare results across studies. The guidelines arose from a working group convened by the Association for Research in Vision and Ophthalmology (ARVO) and the International Agency for the Prevention of Blindness (IAPB).

  9. Study Shows UV-Blocking Contact Lenses Can Protect Eyes from Sun Damage

    Study Shows UV-Blocking Contact Lenses Can Protect Eyes from Sun Damage Beyond Sunglasses and Baseball Caps: Study Shows UV-Blocking Contact Lenses Can Protect Eyes from Sun Damage Rockville, MD - A new study reported in Investigative Ophthalmology and Visual Science found that UV-blocking contact lenses can reduce or eliminate the effects of the sun's harmful UV radiation. According to the article ("Prevention of UV-Induced Damage to the Anterior Segment Using Class I UV Absorbing Hydrogel Con

    How Does an Outfielder Know Where to Run for a Fly Ball? How Does an Outfielder Know Where to Run for a Fly Ball?    Virtual-reality baseballs give researchers insight into long-standing mystery Rockville, MD - While baseball fans still rank "The Catch" by Willie Mays in the 1954 World Series as one of the greatest baseball moments of all times, scientists see the feat as more of a puzzle: How does an outfielder get to the right place at the right time to catch a fly ball? Thousands of fans (a
