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...

Using new technology and new approaches, researchers at Lund University in Sweden hope to be able to explain why people suffer vision loss in eye diseases such as retinal detachment and glaucoma. Research on diseases of the eye such as retinal detachment and glaucoma has until now focused on the biochemical process that takes place in the eye in connection with the diseases...

Age-related macular degeneration (AMD) continues to be the leading cause of visual impairment in the United States for people over age 65, according to a study recently published online in Ophthalmology, the journal of the American Academy of Ophthalmology. AMD is a potentially blinding disease that affects more than 9.1 million Americans...

Wearing contact lenses overnight may offer a non-surgical alternative to restoring near vision without the need for glasses, according to a new Australian study that successfully tested the method in middle-aged patients with presbyopia, or age-related loss of near vision...

A new study raises the intriguing possibility that drugs prescribed to lower cholesterol may be effective against macular degeneration, a blinding eye disease. Researchers at Washington University School of Medicine in St. Louis have found that age-related macular degeneration, the leading cause of vision loss in Americans over 50, shares a common link with atherosclerosis...

Until now, researchers looking for the origins of eye diseases like detached retina and glaucoma have focused on biochemical processes...

New research that links the causes of age-related macular degeneration (AMD) with clogged arteries suggests anti-cholesterol drugs may halt the eye disease, the leading cause of blindess among older people in the US. In the 2 April issue of Cell Metabolism, senior investigator Rajendra S. Apte, of the Washington University School of Medicine in St...

By middle age, most people have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses...

After eons of wandering in the dark, primates developed highly acute, three-color vision that permitted them to shift to daytime living, a new Dartmouth College study suggests...

JoVE (Journal of Visualized Experiments) has published a new video article by Dr. Lotfi Merabet showing how researchers in the Department of Ophthalmology at Massachusetts Eye and Ear Infirmary and Harvard Medical School have developed a virtual gaming environment to help blind individuals improve navigation skills and develop a cognitive spatial map of unfamiliar buildings and public locations...

Vision is our most prized sense, but to maintain healthy vision, we need to care for our eyes and have regular checkups.

A new therapeutic target in iron overload disorders Iron is required for multiple cellular functions, including the synthesis of hemoglobin, but a buildup of excess cellular iron can be toxic. Hepcidin is a circulating molecule produced by the liver that triggers the degradation of iron transporters in the intestine and certain immune cells...

Once rhesus monkeys learn to associate a picture with a reward, the reward by itself becomes enough to alter the activity in the monkeys' visual cortex. This finding was made by neurophysiologists Wim Vanduffel and John Arsenault (KU Leuven and Harvard Medical School) and American colleagues using functional brain scans and was published recently in the leading journal Neuron...

A 20-page large-print booklet and a series of videos to help people adapt to life with low vision are available from the National Eye Institute (NEI), a part of the National Institutes of Health.

Research led by a biology professor in the School of Science at IUPUI has uncovered a method to produce retinal cells from regenerative human stem cells without the use of animal products, proteins or other foreign substances, which historically have limited the application of stem cells to treat disease and other human developmental disorders...

Dr. Gareth Howell was awarded the 2013 Shaffer Prize for Innovative Glaucoma Research for his study investigating the mechanism by which a spontaneous mutation prevents retinal ganglion cell death in glaucoma.

David Calkins, PhD, Catalyst for a Cure investigator and Vice Chair and Director of Research for the Vanderbilt Eye Institute, was recently awarded a Research to Prevent Blindness Senior Scientific Investigator Award.
