Macular degeneration involves the retina of the eye. The macula, located near the center of the retina, is responsible for clear, straight-ahead vision. There are two types of macular degeneration: wet and dry. The former develops when fluid and blood leak out into the macula tissue. Dry macular degeneration occurs when the tissue around the macula deteriorates. Central vision gradually decreases, and people may experience blurred spots. Both types worsen over time, though wet macular degeneration can start suddenly and quickly get worse.
