There are two types of age-related macular degeneration: Dry macular degeneration and Wet macular degeneration.

Wet macular degeneration is generally caused by abnormal blood vessels that leak fluid or blood into the region of the macula. Early detection and treatment of wet macular degeneration may help reduce vision loss and, in some instances, improve vision. It is more severe than the dry type and progresses more rapidly. The dry macular degeneration, on the other hand, is more common and less severe. The wet type always begins as the dry type.
