Strategy to prevent age-related macular degeneration identified

A new study from Washington University School of Medicine in St. Louis identifies a possible way to slow or block progression of age-related macular degeneration, a leading cause of blindness in people over age 50. The WashU Medicine researchers and their international collaborators implicated problems with cholesterol metabolism in this type of vision loss, perhaps helping to explain the links between macular degeneration and cardiovascular disease, which both worsen with age.
