Age-related macular degeneration (AMD), an eye disorder associated with aging, gradually causes loss of clear central vision. The retina is located on the inside surface of the back of your eye. The macula, in the center of the retina, is responsible for your reading and fine vision. In AMD, the macula begins to deteriorate, causing symptoms that can range from blurred central vision to a blind spot in the center of vision.

There are two types of AMD -- dry and wet.
