Macular degeneration (MD)

This is the leading cause of irreversible blindness among Americans over 65! The macula is a portion of the retina in the back of the eye. MD occurs when macular cells in the center of the retina become damaged. This is caused in part, by oxidative damage. The retina is particularly susceptible to such damage, because it is exposed to more oxygen than any other organ in the body, except for your skin. Furthermore, the retina contains a high concentration of lipids, easily damaged by oxygen.
