Age-related macular degeneration (ARMD or AMD), also referred to as macular degeneration, is a common eye condition in which the part of the retina called the macula deteriorates, resulting in vision loss. According to The National Eye Institute, macular degeneration is the leading cause of vision loss among people age 50 and older. There are two types of AMD—dry macular degeneration and wet macular degeneration. Dry macular degeneration is more common, and affects 80-90% of people with AMD, according to the American Foundation for the Blind. Its cause is unknown, and it tends to progress slowly. Wet macular degeneration is when the blood vessels under the retina begin to grow abnormally toward the macula. About 10% of dry macular degeneration cases will advance to wet macular degeneration. This type of AMD tends to progress very quickly.
1. Blurred Vision
Sometimes the disease progresses very slowly, and other times the disease progresses quickly. One of the first signs of macular degeneration is a blurred area, usually near the center of vision. The blurred area may start out very small and grow larger over time, with blank spots in the central vision.
