Macular Degeneration – Patient Education Overview

Macular degeneration is an age-related disease of the eye involving the deterioration of the macula – the central part of the retina that lines the eye’s back wall and enables vision of fine details. Symptoms appear gradually starting with blurring or difficulty seeing in dim light as the macula cells die. Read more in our patient education guide.

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

Dry Macular Degeneration

  • More common type (90%)
  • Causes central vision loss or a blind spot in the middle of the visual field
  • Total blindness is not associated with this condition
  • May not affect both eyes
  • Caused by drusen (body byproducts) deposits
  • Amount of deposits determines early, intermediate or advanced stages

Wet Macular Degeneration

  • Started out as dry type
  • Marked by leaky blood vessels in the back of the eye causing swelling
  • Central vision loss
  • More severe than dry type
