 Imagine what it's like to be active your whole life and then find out you're going blind. That's what happened to me. I have age-related macular degeneration, or AMD. As a wife, mother, and grandmother, my sight is precious to me. What a relief when I found out that treatments for some forms of AMD are available and that research is underway on additional preventions and treatments. AMD is the leading cause of vision loss in people 55 and over.
