Are the dry and wet forms of age-related macular degeneration related?

ANSWER

In the dry form of age-related macular degeneration -- the most common form -- tiny yellow deposits, called drusen, develop beneath the macula, signaling a degeneration and thinning of nerve tissue.

About 10% of cases of dry macular degeneration develop into the wet form, were abnormal blood vessels grow beneath the macula. As these vessels leak blood and fluid onto and underneath the retina, retinal cells die, causing blurring, distortion, and blank spots in your field of vision.
