Wide-eyed expressions that typically signal fear may enlarge our visual field and mutually enhance others' ability to locate threats, according to new research published in Psychological Science, a journal of the Association for Psychological Science. http://medicalxpress.com/news/2013-05-wide-eyed-usand-othersto-threats.html Psychology & Psychiatry Wed, 01 May 2013 15:49:54 EST news286642187 A tiny, EPFL-designed implantable device that can be positioned within the eye and controlled remotely may well revolutionize the treatment of glaucoma. The device should be through testing this year and on its way to the market in 2014 via Rheon Medical, an EPFL spin-off. http://medicalxpress.com/news/2013-03-micro-tap-glaucoma.html Ophthalmology Mon, 25 Mar 2013 09:42:54 EST news283423361 New research suggests that elite athletes – Olympic medalists in volleyball, for example – perform better than the rest of us in yet another way. These athletes excel not only in their sport of choice but also in how fast their brains take in and respond to new information – cognitive abilities that are important on and off the court. http://medicalxpress.com/news/2013-03-elite-athletes-excel-cognitive-tasks.html Psychology & Psychiatry Mon, 18 Mar 2013 18:35:51 EST news282850542 (Medical Xpress)—Dr. Mike Nguyen, a urologist and UA associate professor of surgery, and Hong Hua, a UA professor of optical sciences, have teamed up with the goal of creating a camera that will allow surgeons to view both wide angle and high-resolution, close-up images simultaneously using a single, integrated probe. http://medicalxpress.com/news/2013-01-surgeon-optical-scientist-collaborate-surgery.html Surgery Thu, 17 Jan 2013 07:00:19 EST news277628410 A new study finds that certain changes in blood vessels in the eye's retina can be an early warning that a person is at increased risk for glaucoma, an eye disease that slowly robs people of their peripheral vision. Using diagnostic photos and other data from the Australian Blue Mountains Eye Study, the researchers showed that patients who had abnormally narrow retinal arteries when the study began were also those who were most likely to have glaucoma at its 10-year end point. If confirmed by future research, this finding could give ophthalmologists a new way to identify and treat those who are most vulnerable to vision loss from glaucoma. The study was recently published online by Ophthalmology, the journal of the American Academy of Ophthalmology. http://medicalxpress.com/news/2013-01-early-predictor-glaucoma.html Ophthalmology Wed, 02 Jan 2013 04:27:29 EST news276323220 Her enigmatic expression has been the topic of artistic debate for hundreds of years. But the reason the Mona Lisa's mouth—part smile, part pursed lip—is so confounding has to do with the eyes, according to one Harvard scientist. http://medicalxpress.com/news/2012-11-art-neurobiologist-eye.html Psychology & Psychiatry Mon, 19 Nov 2012 07:23:30 EST news272532197 The first study to compare accident rates for drivers who have advanced glaucoma − an eye disease that affects peripheral vision − with normal-vision drivers, found that the glaucoma group had about twice as many accidents. This study, which was conducted in Japan using a driving simulator, suggests that potential drivers should pass a visual field test to ensure adequate peripheral vision before a license is granted or renewed. The research is being presented today at the 116th Annual Meeting of the American Academy of Ophthalmology, jointly conducted this year with the Asia-Pacific Academy of Ophthalmology. http://medicalxpress.com/news/2012-11-glaucoma-related-vision-loss-auto-accidents.html Diseases, Conditions, Syndromes Sun, 11 Nov 2012 10:32:27 EST news271852323 (Medical Xpress) -- Neuroscientists have discovered a new area of the brain that is uniquely specialized for peripheral vision and could be targeted in future treatments for panic disorders and Alzheimer’s disease. http://medicalxpress.com/news/2012-07-brain-discovery-link-vision-emotion.html Neuroscience Tue, 24 Jul 2012 09:02:10 EST news262339319 (Medical Xpress) -- Two USC scientists are bringing peripheral vision into focus, showing that the way the brain sharpens its attention while the eyes are in motion leads to false assumptions about how objects should look. http://medicalxpress.com/news/2012-01-scientists-eyes-peripheral-vision.html Neuroscience Fri, 20 Jan 2012 08:46:49 EST news246271601 (Medical Xpress) -- A world-first Queensland University of Technology (QUT) study has found that people suffering from more extensive vision loss from glaucoma are at a higher risk of having a fall than those with better vision. http://medicalxpress.com/news/2011-11-people-vision-loss-glaucoma-higher.html Health Wed, 09 Nov 2011 10:31:17 EST news240056990 (Medical Xpress) -- Technology developed at the University of Cambridge to detect peripheral visual field loss in young children will enable the earlier detection of brain tumours, potentially saving sight and lives. http://medicalxpress.com/news/2011-10-children-vision-loss-video.html Medical research Wed, 12 Oct 2011 06:49:42 EST news237620965 People who are deaf benefit from better vision due to the fact their retinas develop differently, experts at the University of Sheffield have shown. http://medicalxpress.com/news/2011-06-retina-key-vision-deaf-people.html Medical research Wed, 01 Jun 2011 17:48:01 EST news226169268 (PhysOrg.com) -- An eye consultant has drawn on his teenage passion for computer programming to create a special test to check the vision of children as young as four, in a way that can flag up problems caused by glaucoma, drug side-effects, brain tumours and other conditions. http://medicalxpress.com/news/2011-05-game-eye-specialists-disease-children.html Diseases, Conditions, Syndromes Fri, 20 May 2011 07:47:29 EST news225096373
