Causes:

Age is the most common cause of AMD, however smoking, obesity, race, family history, and gender can all play a role.

Symptoms:

AMD causes no pain so sometimes it is difficult to know in advance of the disease. In some cases, AMD advances so slowly that people notice little change in their vision. In others, the disease progresses faster and may lead to a loss of vision in both eyes.

Types:

    Wet Macular Degeneration
  • Wet Degeneration (Advanced AMD) occurs when abnormal blood vessels behind the retina start to grow under the macula and begin to leak blood and fluid. An early symptom of wet AMD is that straight lines appear wavy.

  • Dry Macular Degeneration
  • Dry Degeneration occurs when the light-sensitive cells in the macula deteriorate causing blurred central vision. An early symptom of dry AMD is blurred vision and trouble recognizing faces.

Diagnosis:

Major factors in determining if a patient has AMD:
  • Eye drops to dilate
  • Visual acuity testing
  • Sensitive central vision (Macular) testing with visual field equipment
  • Digital imaging of the Maculae
  • Home monitoring of central vision by Amsler Grid test to determine if your vision ever gets blurred or wavy
  • Genetic risk determination and counseling
