Macular Degeneration

Macular degeneration is a deterioration of the macula. The macula is a small area in the retina at the back of the eye that allows you to see fine details clearly and perform activities such as reading and driving. When the macula does not function correctly, your central vision can be affected by blurriness, dark areas, or distortion. 

Although macular degeneration reduces vision in the central part of the retina, it usually does not affect the eye’s side, or peripheral, vision. For example, you could see the outline of a clock but not be able to tell what time it is.

Macular degeneration alone does not result in total blindness. Even in more advanced cases, people continue to have some useful vision and often are able to take care of themselves. In many cases, macular degeneration’s impact on your vision can be minimal.


What Are the Symptoms of Macular Degeneration?

Macular degeneration can cause different symptoms in different people. The condition may be hardly noticeable in its early stages. Sometimes only one eye loses vision while the other eye continues to see well for many years. But when both eyes are affected, the loss of central vision may be noticed more quickly.

Following are some common ways vision loss is detected:

  • words on a page look blurred;
  • dark or empty area appears in the center of vision;
  • straight lines look distorted, as in the following diagram.




Nutritional Supplements

Testing Your Vision With the Amsler Grid

You can check your vision daily by using an Amsler grid like the one pictured here. You may find changes in your vision that you wouldn’t notice otherwise. 


To use the grid:

  1. Wear your reading glasses and hold this grid 12 to 15 inches away from your face in good light.
  2. Cover one eye.
  3. Look directly at the center dot with the uncovered eye.
  4. While looking directly at the center dot, note whether all lines of the grid are straight or if any areas are distorted, blurred or dark.
  5. Repeat this procedure with the other eye.
  6. If any area of the grid looks wavy, blurred or dark, contact your ophthalmologist.
