vision

Some doctors and a key group of preventive care experts aren't seeing eye to eye on seniors' need for vision screening during primary care visits.

I'm a retinal specialist, an ophthalmologist who specializes in the back of the eye. I see a good number of patients with age-related macular degeneration, or AMD, a disease that limits central vision. It affects at least 6 percent of the population, and the more severe form with significant vision loss will affect about 3 million people by the year 2020.

A potential new cure for blindness is showing promise in an experiment at the University of Washington and University of California. The study shows that losing your eyesight as you grow older may someday be reversible. 

The experiment used mice – blind mice.
