Diopsys VEP technology indicates functional abnormalities in early glaucoma patients where visual field testing fails. Pine Brook, NJ (PRWEB) June 28, 2013 To better evaluate patients with degenerative vision problems, a team of researchers from New York Eye and Ear Infirmary recently concluded that the Diopsys® NOVA-LX VEP vision test may be useful for diagnosis of glaucoma with structural abnormalities where visual field tests indicate normal vision. The outcome of their study...

Rat's Move Their Eyes In Opposite Directions When Running For Unique View
2013-05-28 14:17:27

Lee Rannals for redOrbit.com — Your Universe Online Max Planck Institute (MPG) scientists have found that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running. This gives the rats a unique perspective on the world around them. The team discovered that each rat eye moves in a different direction, depending on the change in the animals' head position. They analyzed both eyes and found that one of the eye movements exclude the...

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...

UC Berkeley study shows how we refocus to track down a human, animal or thing A contact lens on the bathroom floor, an escaped hamster in the backyard, a car key in a bed of gravel: How are we able to focus so sharply to find that proverbial needle in a haystack? Scientists at the University of California, Berkeley, have discovered that when we embark on a targeted search, various visual and non-visual regions of the brain mobilize to track down a person, animal or thing. That means...

Challenging The Brain's Visual System In New Environments
2013-04-12 05:12:08

redOrbit Staff & Wire Reports - Your Universe Online When people escape from the grind of their day-to-day lives and travel to remote, tranquil places, they often claim to “turn off” their brains so that they can soak in the calm, relaxing environment. Despite how restful things might seem, however, new research from the Salk Institute for Biological Studies in California reveals that a person´s mind — and more specifically, their visual system — is working...

Rodents recognize objects using sophisticated perceptive strategies Sight is such a spontaneous activity that we are unaware of the complexity of the brain mechanisms it implies. For instance, we easily recognize objects, which appear to look always the same, without realizing that we observe them from ever-changing points of view and that their image — the luminance profile cast onto the retina —varies significantly each time we look at them. To maintain such "invariance"...

One Step Closer To Understanding The Origins Of Eye Disease
2013-04-04 06:12:35

Jason Pierce, MSN, MBA, RN for redOrbit.com — Your Universe Online Researchers at Lund University in Sweden have published a study describing the use of an innovative process to examine the effect of tension in maintaining retinal tissue. The method allows the retinal tissue to be studied outside the body while simulating the mechanical strain experienced by the tissue in the human body. The authors anticipate that the method will lead to better understanding of the reason for vision...
