Age-related macular degeneration (AMD) is a disease of the macula, the area of the retina responsible for sharp central vision. Symptoms include blurry or fuzzy vision, darkness in the central portion of the visual field, and wavy lines that should appear straight. There are two types of the disease. About 90 percent of all cases are “dry” AMD, in which the light-sensitive cells in the macula slowly break down to cause gradual loss of central vision. “Wet” AMD occurs when fragile new blood vessels behind the retina leak blood and fluid under the macula, causing rapid deterioration of central vision. Wet AMD is treated with lasers or injected medication, while dry AMD can be treated with specific vitamins and minerals.
P.S. While no treatment is currently available to reverse dry macular degeneration, the disease is usually only slowly progressive, and taking high-dose antioxidants and zinc can delay and possibly prevent intermediate AMD from progressing to severe vision loss.
