Researchers home in on genes linked to age-related macular degeneration

National Eye Institute scientists led a collaborative study and zeroed in on genes associated with age-related macular degeneration (AMD), a leading cause of vision loss and blindness among people age 65 and older. These findings provide a more expanded and in-depth picture of the genetic contributions to AMD, and they present new pathways for treatment… Read More »
