A screening eye examination, including detailed examination of the retina, is recommended for all persons 40 years or older. If your eye doctor discovers drusen or other signs of AMD, it is important to have frequent eye examinations. Your eye doctor can provide you with an Amsler grid (a piece of graph paper with thick, dark lines) that you can use to test your vision each day. If the lines appear wavy or distorted, you should see your eye doctor immediately because it may be a sign of wet AMD. Your eye doctor may recommend the daily use of zinc and antioxidant vitamins (vitamin C, vitamin E, and beta carotene), which have been shown to reduce the risk of developing more severe forms of AMD.
