macular degeneration

Age Related Macular Degeneration (AMD) is a degenerative disease of the retina that affects one's ability to see in the center of their visual field. It typically affects people over the age of 50 and decreases vision by destroying the macula.

The macula, which is located in the central portion of the retina, is responsible for focusing central vision which is needed for seeing fine detail, reading, driving, and recognizing facial features.

There are two types of macular degeneration: dry and wet.

In the wet type, visual loss occurs when abnormal blood vessels grow and leak intot he space beneath the retina. Components of the blood are toxic to the retina, destroying the cells which are exposed to it.

In the dry type, which accounts for only 10 percent of the people who lose their vision, causes deposits of abnormal fatty substances called drusen to form that destroy the retina and the ability to see.

Risk factors associated with AMD include:

  • Smoking
  • Obesity
  • Age over 50
  • Fair Skin
  • Light Colored Eyes
  • Diabetes
  • Family History of AMD
  • Sun Exposure as a child
  • Lack of exercise
  • Poor dietary intake of antioxidants and essential fatty acids
