Macular Degeneration

Macular degeneration is a disease of the macula, an area of the retina at the back of the eye that is responsible for fine detail vision. Vision loss usually occurs gradually and typically affects both eyes at different rates. Even with a loss of central vision, however, color vision and peripheral vision may remain clear.

Symptoms of macular degeneration:

  • Early macular degeneration may cause little, if any noticeable change in vision
  • Difficulty reading without extra light and magnification
  • Seeing objects as distorted or blurred, or abnormal in shape, size or color
  • The perception that objects "jump" when you try to look right at them
  • Difficulty seeing to read or drive
  • Inability to see details
  • Blind spot in center of vision

There are two forms of age-related macular degeneration, wet and dry.

Wet macular degeneration

Wet macular degeneration occurs when abnormal or leaking blood vessels grow underneath the retina in the area of the macula. These changes can lead to distorted or blurred vision and, in some cases, a rapid and severe loss of straight ahead vision.

Dry macular degeneration

The vast majority of cases of macular degeneration are the dry type, in which there is thinning or deterioration of the tissues of the macula or the formation of abnormal yellow deposits called drusen. Progression of dry macular degeneration occurs very slowly and does not always affect both eyes equally.

Causes of or contributing factors to macular degeneration:

The root causes of macular degeneration are still unknown. Women are at a slightly higher risk than men. Caucasians are more likely to develop macular degeneration than African Americans.

  • Age: Macular degeneration is the leading cause of decreased vision in people over 65 years of age.
  • Heredity: Macular degeneration appears to be hereditary in some families but not in others
  • Long-term sun exposure
  • Smoking
  • High blood pressure
  • High cholesterol
  • Hypertension
  • Nutritional deficiencies
  • Diabetes
