Macular Degeneration

It occurs when the macula of the eye lose its proper structure .The blood vessels and the proteins present in the body including cholesterol  affect the eye sight of the people suffering from this disease. .Age-related macular degeneration is the leading cause of blindness in most developed countries.


  • Damage to the area around blood vessels that supply the macula.
  • Hereditary
  • Caucasian race
  • Cigarette smoking
  • High-fat diet
  • Female gender
  • Obesity


  1. Dry macular degeneration

Occurs when the blood vessels under the macula become thin and brittle. Small yellow deposits, called drusen, form. Almost all people with macular degeneration start with the dry form.

  1. Wet macular degeneration

Occurs in only about 10% of people with macular degeneration. New abnormal and very fragile blood vessels grow under the macula. This is called choroidal neovascularization. These vessels leak blood and fluid. This form causes most of the vision loss associated with the condition.
