(PhysOrg.com) -- Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. The reason they can do this, researchers suggest, is that in at least some circumstances, blindness can heighten other senses, helping individuals adapt. http://www.physorg.com/news177773741.html Medicine & Health Wed, 18 Nov 2009 14:20:04 EST news177773741 Schepens Eye Research Institute scientists have found that--when tested in a driving simulator--patients with hemianopia (blindness in one half of the visual field in both eyes) have significantly more difficulty detecting pedestrians (on their blind side) than normally sighted people. These results, published in the November 2009 issue of Investigative Ophthalmology and Visual Science, fly in the face of some recent on-road studies that have found most people with hemianopia safe to drive. http://www.physorg.com/news177250328.html Medicine & Health Thu, 12 Nov 2009 13:00:02 EST news177250328 Intel Corporation today announced the Intel Reader, a mobile handheld device designed to increase independence for people who have trouble reading standard print. http://www.physorg.com/news177146151.html Electronics Wed, 11 Nov 2009 07:30:02 EST news177146151 Born with a retinal disease that made him legally blind, and would eventually leave him totally sightless, the nine-year-old boy used to sit in the back of the classroom, relying on the large print on an electronic screen and assisted by teacher aides. Now, after a single injection of genes that produce light-sensitive pigments in the back of his eye, he sits in front with classmates and participates in class without extra help. In the playground, he joins his classmates in playing his first game of softball. http://www.physorg.com/news175692544.html Medicine & Health Sun, 25 Oct 2009 12:29:40 EST news175692544 Everyone tends to float off into space once in a while and fail to see what is sitting there right in front of them. Recently researchers decided to put the theory of "inattentional blindness" to the test: the unicycling clown test. They documented real-world examples of people who were so distracted by their cell phone use that they failed to see the bizarre occurrence of a unicycling clown passing them on the street. The study is published in an upcoming issue of Applied Cognitive Psychology. http://www.physorg.com/news175190497.html Medicine & Health Mon, 19 Oct 2009 17:30:03 EST news175190497 Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly. The same process also allows the eye to function in bright light. http://www.physorg.com/news174663395.html Medicine & Health Tue, 13 Oct 2009 14:37:50 EST news174663395 As more extremely pre-term infants survive in Sweden, an increasing number of babies are experiencing vision problems caused by abnormalities involving the retina, according to a report in the October issue of Archives of Ophthalmology.. http://www.physorg.com/news174585039.html Medicine & Health Mon, 12 Oct 2009 17:30:08 EST news174585039 Investigators from Boston University School of Medicine (BUSM) and the VA Boston Healthcare System have shown, at 6 months in a small group of patients, that there is no difference in efficacy between Bevacizumab (Avastin) and Ranibizumab (Lucentis) for the treatment of age-related macular degeneration (AMD). The study, which appears currently on-line in the American Journal of Ophthalmology, is the first to report early outcomes of a prospective, double-masked, randomized, controlled trial comparing Bevacizumab to Ranibizumab for the treatment of exudative (wet) age-related macular degeneration. http://www.physorg.com/news174302546.html Medicine & Health Fri, 09 Oct 2009 10:50:02 EST news174302546 Researchers at the University of Toronto, St. Michael's Hospital and Sunnybrook Health Sciences Centre have discovered a previously unidentified form of circulation within the human eye which may provide important new insights into glaucoma, a leading cause of blindness. http://www.physorg.com/news173966488.html Medicine & Health Mon, 05 Oct 2009 13:30:02 EST news173966488 (PhysOrg.com) -- Inspired by the success of cochlear implants that can restore hearing to some deaf people, researchers at MIT are working on a retinal implant that could one day help blind people regain a useful level of vision. http://www.physorg.com/news172920565.html Technology Wed, 23 Sep 2009 10:30:36 EST news172920565 (PhysOrg.com) -- Cases of restored vision after a lifetime of blindness, though exceedingly rare, provide a unique opportunity to address several fundamental questions regarding brain function. After being deprived of visual input, the brain needs to learn to make sense of the new flood of visual information. Very little is known about how this learning takes place, but a new study by MIT neuroscientists suggests that dynamic information -- that is, input from moving objects -- is critical. http://www.physorg.com/news172400454.html Medicine & Health Thu, 17 Sep 2009 10:01:25 EST news172400454 (PhysOrg.com) -- Researchers from the University of Washington and the University of Florida used gene therapy to cure two squirrel monkeys of color blindness - the most common genetic disorder in people. http://www.physorg.com/news172325926.html Medicine & Health Wed, 16 Sep 2009 13:19:09 EST news172325926 The blind and visually impaired often rely on others to provide cues and information on navigating through their environments. The problem with this method is that it doesn't give them the tools to venture out on their own, says Dr. Orly Lahav of Tel Aviv University's School of Education and Porter School for Environmental Studies. http://www.physorg.com/news171802541.html Technology Thu, 10 Sep 2009 11:56:42 EST news171802541 By 2020, 1.4 million Nigerians over age 40 will lose their sight, and the vast majority of the causes are either preventable or treatable, according to the Nigeria National Blindness and Visual Impairment Study Group. http://www.physorg.com/news171626824.html Medicine & Health Tue, 08 Sep 2009 11:07:26 EST news171626824 (AP) -- The Helen Keller International nonprofit organization has won a $1.4 million prize from a Portuguese foundation for its work in preventing blindness in the developing world, the foundation said Friday. http://www.physorg.com/news171351089.html Medicine & Health Sat, 05 Sep 2009 06:50:01 EST news171351089 Significant numbers of children in the UK are suffering from preventable levels of disability, particularly blindness, and premature death because of poor diagnosis of brain tumours. http://www.physorg.com/news168857999.html Medicine & Health Fri, 07 Aug 2009 10:30:01 EST news168857999 Researchers have found a way in mice to convert another type of pancreas cell into the critical insulin-producing beta cells that are lost in those with type I diabetes.
