Chemical Temporarily Reverses Blindness in Mouse Model - Review of Ophthalmology (August 8, 2012) - A team of University of California, Berkeley, scientists in collaboration with researchers at the University of Munich and University of Washington in Seattle has discovered a chemical that temporarily restores some vision to blind mice, and is working on an improved compound that may someday allow people with degenerative blindness to see again. The approach could eventually help those with retinitis pigmentosa, as well as age-related macular degeneration. In both diseases, rods and cones die, leaving the eye without functional photoreceptors.   read more  

Blacks More Vulnerable to High HbA1c Levels - Annals of Internal Medicine (August 7, 2012) - Blacks are more likely to develop diabetic eye damage at lower blood glucose thresholds than whites, according to a recent study in the Annals of Internal Medicine. The results suggest that black people may be more vulnerable than whites to high HbA1c levels.   read more
