Dr. Susana T.L. Chung receives Glenn A. Fry Lecture Award for research on 'visual plasticity' in older adults Perceptual learning techniques may provide a useful new approach to rehabilitation in patients with central vision loss–taking advantage of visual plasticity that persists even in old age, according to a special article in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams...

University of California - Santa Barbara In a remote fishing community in Venezuela, a lone fisherman sits on a cliff overlooking the southern Caribbean Sea. This man —— the lookout —— is responsible for directing his comrades on the water, who are too close to their target to detect their next catch. Using abilities honed by years of scanning the water's surface, he can tell by shadows, ripples, and even the behavior of seabirds, where the fish are schooling, and...

Optical media changes with age, but neural mechanisms keep color perception constant Cone receptors in the human eye lose their color sensitivity with age, but our subjective experience of color remains largely unchanged over the years. This ability to compensate for age-related changes in color perception rests in higher levels of the visual system, according to research published May 8 in the open access journal PLOS ONE by Sophie Wuerger from the University of Liverpool, UK. The...

Scientists Look At How The Brain Compensates For Speed
2013-05-08 18:47:22

Michael Harper for redOrbit.com — Your Universe Online Researchers from the University of California in Berkeley have finally pinpointed the area of the brain responsible for not only seeing fast-moving objects, but responding to them as well. This development explains why athletes are able to react and respond to balls traveling at speeds upwards of 100 miles an hour. According to this research, our brains are capable of “pushing” fast moving objects, so we perceive...

Playing Tetris To Treat Lazy Eye

Michael Harper for redOrbit.com — Your Universe Online Tetris is more than a fun and exciting way to practice your skills at packing a moving truck. According to new study, the iconic Russian tile-matching game created by Alexey Pajitnov in 1984 can also be used to correct amblyopia, or lazy eye. This condition is caused when the brain sends imbalanced processing signals and favors one eye over the other. New research from the McGill University in Montreal has looked into the...

A new study finds that the Diopsys NOVA-LX Visual Evoked Potential (VEP) Vision Testing System can help optometrists and ophthalmologists distinguish healthy from glaucomatous eyes, which is especially helpful in the early detection of the disease. Pine Brook, NJ (PRWEB) March 29, 2013 The Diopsys® NOVA-LX Visual Evoked Potential (VEP) Vision Testing System has proven to be an effective tool for glaucoma detection. New research by New York Eye and Ear Infirmary just published in...

New Artificial Retina Partially Restores Sight
2013-02-15 10:56:46

Jason Pierce, MSN, MBA, RN for redOrbit.com — Your Universe Online Today the US Food and Drug Administration (FDA) approved an artificial retina that is the first device of its kind to treat a form of progressive blindness that begins in young adulthood. The device will not completely restore vision, but it does allow the wearer to detect differences in light patterns and some shapes from their environment. The Argus II Retinal Prosthesis System, developed by Second Sight Medical...

Scientists have developed a quick, easy and cheap vision test to find out which part — and how much — of the brain of a stroke victim has been damaged, potentially enabling them to save more lives. The test requires patients to look into a device for about ten minutes, enabling it to be used in the early stages of a stroke — even if the patient cannot move their limbs or speak. This can help doctors diagnose and treat the stroke quickly and accurately, which is vital,...

New Sound Device Teaches Blind People To See
2012-11-08 08:57:31

[WATCH VIDEO: Examples of Visual Stimuli Used in SSD Training] Lawrence LeBlond for redOrbit.com - Your Universe Online It has been long believed that blindness in early infanthood makes sight restoration later in life next to impossible as the brain´s visual cortex has been deprived of visual information. But some researchers have shown that blind people, even those with lifelong blindness, can learn to process visual input using sound. Working from the Hebrew University of...
