The macula is in the center of the retina, the light-sensitive layer of tissue at the back of the eye. As you read, light is focused onto your macula. There, millions of cells change the light into nerve signals that tell the brain what you are seeing. This is called your central vision. With it, you are able to read, drive, and perform other activities that require fine, sharp, straight-ahead vision.
Macular degeneration is damage to the central part of the retina called the macula. The macula is a small area of the retina that allows us to see fine details clearly. When the macula doesn’t function correctly, we experience blurriness or distortion in the center of our vision. Macular degeneration affects both distance and close vision, and can make some activities – like threading a needle or reading – difficult or impossible. Macular degeneration is the leading cause of central vision loss among older people.
There are two types of macular degeneration. A “dry” type that can cause a decrease in your central vision and a “wet” type that can lead to further loss of your central vision.
Normal use of your eyes will not cause further damage to your vision. Even if you have lost sight to AMD, you should not be afraid to use your eyes for reading, watching TV, and other usual activities.
If you have dry AMD, you should have your eyes examined by an ophthalmologist through dilated pupils at least once a year. You should also obtain an Amsler grid from your ophthalmologist to use at home. Also check your vision by reading the newspaper, watching television, and just by looking at people’s faces. If you have wet AMD, it is important not to delay laser surgery if your ophthalmologist advises you to have it. You should protect your macula by wearing sunglasses and taking a special vitamin supplement for the eyes. Contact your ophthalmologist regarding the names of these vitamin supplements.
