Retinitis Pigmentosa In Dogs Cured By Gene Therapy published
Tue, 24 Jan 2012 02:00:00 PST
Members of a University of Pennsylvania research team have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs. The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man...

Age-Related Blindness May Be Warded Off By Grapes published
Fri, 13 Jan 2012 00:00:00 PST
Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects...
Increasing Need For Rehabilitation For Eye Disease published
