Progressive degeneration of photoreceptors—the rods and cones of the eyes—causes blinding diseases such as retinitis pigmentosa and age-related macular degeneration. While there are currently no available treatments to reverse this degeneration, a newly developed compound allows other cells in the eye to act like photoreceptors. As described in a study appearing in the February 19 issue of the Cell Press journal Neuron, the compound may be a potential drug candidate for treating patients...

Researchers Find Easier Way To Perform Macular Degeneration Eye Test
2012-10-08 12:33:58

Lawrence LeBlond for redOrbit.com - Your Universe Online Age-related Macular Degeneration (AMD) is a condition that generally occurs in people over the age of 50, but also occurs in higher numbers of people who smoke, who are white, and people who have a family history of the often debilitating condition. And for those who had gone through AMD testing, they had generally had to sit in a darkened room for 20 minutes before testing had begun. But now, researchers from Australia´s...

Color Blindness Linked To Eye Cells Not Brain

Alan McStravick for redOrbit.com - Your Universe Online Over the past few years, several advances have been made in the field of ocular health.  Much of the research in color vision deficiencies has been conducted in Australia by researchers at The Vision Centre and The University of Sydney. Only a few months back, a major leap forward was achieved in the area of cortical color blindness caused by a traumatic brain injury. That study, like most others, focused on searching the...

Research conducted at the Angiogenesis Laboratory at Massachusetts Eye and Ear Infirmary, has for the first time, identified the mode of death of cone photoreceptor cells in an animal model of retinitis pigmentosa (RP). This groundbreaking study, led by Demetrios G. Vavvas, M.D., Ph.D., and including Joan W. Miller, M.D., Mass. Eye and Ear/Mass General Hospital Chief of Ophthalmology and Chair of Ophthalmology at Harvard Medical School, has further identified the receptor interacting protein...

Scientists funded by the Medical Research Council (MRC) have shown for the first time that transplanting light-sensitive photoreceptors into the eyes of visually impaired mice can restore their vision. The research, published in Nature, suggests that transplanting photoreceptors — light-sensitive nerve cells that line the back of the eye — could form the basis of a new treatment to restore sight in people with degenerative eye diseases. Scientists from UCL Institute of...

After more than three decades of research, University of Pennsylvania veterinarians and vision-research scientists, with associates at Cornell University, have identified a gene responsible for a blindness-inducing disease that afflicts dogs. In the process, the Penn scientists may have discovered clues about how retinal cells, and perhaps even neurons, can be regenerated. The research was conducted by Gustavo D. Aguirre, William A. Beltran, Agnes I. Berta and Sem Genini of Penn's School...

New research in the FASEB Journal provides insight into the molecular basis of one form of retinal degeneration, Enhanced S-Cone Syndrome also known as Goldman-Favre Syndrome A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome. In the...

The human eye long ago solved a problem common to both digital and film cameras: how to get good contrast in an image while also capturing faint detail. Nearly 50 years ago, physiologists described the retina's tricks for improving contrast and sharpening edges, but new experiments by neurobiologists at University of California, Berkeley and the University of Nebraska Medical Center in Omaha show how the eye achieves this without sacrificing shadow detail. These details will be published next...

In this month's Physics World, Richard Taylor, professor of physics, psychology and art at the University of Oregon, warns that artificial retinal implants "“ a technology fast becoming a reality "“ must adapt to the unique features of the human eye in order to become an effective treatment. The gap between digital camera technology and the human eye is getting ever smaller, in terms of both the number of light-sensitive detectors and the space that they occupy. A human retina...

According to a laboratory study published on Tuesday, sharks may be unable to distinguish between colors, which could benefit swimmers, fishermen and sharks themselves. Australian researchers looked at the retinal cells of 17 shark species caught off Queensland and Western Australia. They found that the most common kind of light receptors were "rod" cells, which are highly sensitive to light and allow night vision but cannot tell colors apart. However, the sharks lacked cone cells, which...
