Age-related macular degeneration AMD is a leading cause of severe vision loss among Americans ages 65 and over. Knowing your risk factors, being aware of your family history, and keeping regular appointments with your Eye M.D. can help reduce your risks for vision loss from macular degeneration. In its most severe form, known as wet AMD, the disease can lead to permanent loss of central vision which is essential for driving, reading, and recognizing faces.
March is AMD Awareness Month, and the American Academy of Ophthalmology, through its EyeSmart™ Campaign, encourages Americans to know their risks for AMD.
“The past few years have been marked by significant improvement in understanding the causes and the treatment of AMD,” says George Williams, MD, an AMD expert and Academy clinical correspondent. “New research and clinical advances are helping us to better treat both the “dry” AMD and “wet” forms of AMD. One strong risk factor that people may not be aware of is family history. It’s important to find out whether your relatives have had AMD, and to tell your Eye M.D., if you have a history of AMD in your family. Knowing your risks can save your sight.”
Here are the top 5 risk factors for AMD:
If you have any two of these risk factors, you should schedule an appointment with your Eye M.D for a complete evaluation. Your Eye M.D. may recommend certain preventive measures which can reduce your risk of vision loss from this disorder.
People who are at risk should know the symptoms of wet AMD, the form most likely to cause rapid and serious vision loss. These include sudden, noticeable loss or distortion of vision, such as seeing “wavy” lines. See an Eye M.D. right away if these symptoms occur. Current treatments for wet AMD provide an excellent chance of stopping vision loss and may actually restore some vision when macular degeneration develops. Earlier diagnosis of wet AMD gives a better chance of successful treatment.
There are some AMD risk factors that a person can change such as smoking and diet to reduce the risk of vision loss from AMD. Other risk factors such as genetic factors cannot be changed. However, knowing your family medical history is one way to learn whether you may be genetically predisposed to a disease. One way to reduce AMD risk is to quit smoking or never start. For patients at high risk for developing late-stage AMD, taking a dietary supplement of vitamin C, vitamin E and beta carotene, along with zinc, has been shown to lower the risk of AMD advancing to advanced stages by 25 percent. Patients should check with their Eye M.D. before starting any dietary supplement.
About AMD
The disease takes two forms, termed “dry” and “wet.”
Although only about 10 percent of the 10 to 15 million Americans with AMD have the “wet” form, it is responsible for most severe vision loss. New, highly effective treatments such as the injectable medications ranibizumab and bevacizumab are dramatically reducing damage from “wet” AMD and can stabilize vision in more than 90 percent of patients and actually improve vision in up to 30 to 40 percent of patients.

About the American Academy of Ophthalmology
The American Academy of Ophthalmology is the world's largest association of eye physicians and surgeons — Eye M.D.s — with more than 29,000 members worldwide. Eye health care is provided by the three “O’s” – opticians, optometrists and ophthalmologists. It is the ophthalmologist, or Eye M.D., who can treat it all: eye diseases and injuries, and perform eye surgery. To find an Eye M.D. in your area, visit the Academy's Web site at www.aao.org.
