Gender
Race
Caucasians are much more likely to lose vision from macular degeneration than African Americans are.
Smoking
Smoking may increase the risk of macular degeneration.
Family History
Those with immediate family members who have macular degeneration are at a higher risk of developing the disease.
Obesity
Research studies suggest a link between obesity and the progression of early and intermediate stages of macular degeneration to advanced macular degeneration.
Summary of the Causes of Macular Degeneration
People who have known risk factors for macular degeneration do not always get the disease. On the other hand, many who get macular degeneration have none of these risk factors.
Macular degeneration research scientists do not know the causes of macular degeneration, but they continue to search for them.
People who think they may be at risk for macular degeneration should discuss this concern with their eye doctor. The doctor may suggest ways to reduce the risk and can plan an appropriate schedule for checkups. People over age 60 are at the highest risk, and should get an eye exam at least every two years.
