What Causes AMD?Thursday, April 19, 2012 - 14:15
Scientists don't know. Factors associated with the aging process obviously play a big role, since AMD occurs as people grow older. Heredity is another factor. People with a close relative who had AMD have a greater chance of developing AMD themselves. The "wet" form (see below) is associated with smoking and high blood pressure.
Experts disagree about the role of nutrients in AMD. Some think that lack of certain nutrients in the diet, especially zinc, may increase the chances of getting AMD.
