Age is a major risk factor for age-related macular degeneration (AMD). The disease is most likely to occur after age 60, but it can occur earlier. Other risk factors for AMD include:
� Smoking. Research shows that smoking doubles the risk of AMD.
� Race. AMD is more common among Caucasians than among African-Americans or Hispanics/Latinos.
� Family history and genetics. People with a family history of AMD are at higher risk. At last count, researchers had identified nearly 20 genes that can affect the risk of developing AMD. Many more genetic risk factors are suspected. You may see offers for genetic testing for AMD. Because AMD is influenced by so many genes plus environmental factors such as smoking and nutrition, there are currently no genetic tests that can diagnose AMD, or predict with certainty who will develop it. The American Academy of Ophthalmology currently recommends against routine genetic testing for AMD, and insurance generally does not cover such testing.
Researchers have found links between AMD and some lifestyle choices, such as smoking. You might be able to reduce your risk of AMD or slow its progression by making these healthy choices:
� Avoid smoking
� Exercise regularly
� Maintain normal blood pressure and cholesterol levels
� Eat a healthy diet rich in green, leafy vegetables and fish
