Macular degeneration is the leading cause of severe vision loss in people over age 60. It occurs when the small central portion of the retina, known as the macula, deteriorates. The retina is the light-sensing nerve tissue at the back of the eye. Because the disease develops as a person ages, it is often referred to as age-related macular degeneration (AMD). Although macular degeneration is almost never a totally blinding condition, it can be a source of significant visual disability.

If you’re in the early stages of age-related macular degeneration you may not have symptoms. The first sign you may notice is a gradual or sudden change in the quality of your vision or that straight lines appear distorted to you. This may gradually turn into a dramatic loss of your central vision.

Other symptoms include:

• Dark, blurry areas or whiteout that appears in the center of your vision
• In rare cases, you may have a change in your perception of color

For age-related macular degeneration, you should see a doctor called an ophthalmologist. They specialize in eye care and surgery.

In general, if you’re older than 45 you should get a complete eye exam and then follow-up exams every 2 to 4 years.

If you have age-related macular degeneration, check your vision every day and let your doctor know if you notice any changes.

Keep in mind that vision problems could also be signs of another condition besides macular degeneration. Work with your doctor to get the right treatment for you.
