Macular Degeneration Q&A

What are the symptoms of macular degeneration?

Macular degeneration causes various symptoms, most of which appear gradually. Typically, symptoms occur in both eyes, but they can affect just one. The most common macular degeneration symptoms include:

  • Visual distortions
  • Blurry central vision
  • Difficulty seeing in low light
  • Trouble recognizing faces
  • Need for bright light
  • Decrease in colors


Although most people with macular degeneration don’t go completely blind, they may struggle with activities like reading and driving.

What causes macular degeneration?

Macular degeneration results when the macula, the part of your retina responsible for your central vision, thins. The causes of this degeneration are unknown, but there appear to be both environmental and hereditary factors.

As the eye ages, the macula thins as its cells deteriorate. Specific risk factors have been identified, including smoking and obesity. Those with cardiovascular disease or high blood pressure may also have an increased risk.

How is macular degeneration diagnosed?

A special camera that takes a high-resolution retinal photograph can reveal early signs of macular degeneration. Dr. K may also provide visual field testing. A tool called an Amsler grid is also useful to check for visual disturbances.

Further testing may also be needed, such as optical coherence tomography, which creates an enlarged 3D image of your retina that will allow Dr. K to see damage or swelling.

How is macular degeneration treated?

Although there are no medical treatments for the beginning stages of macular degeneration, lifestyle changes can improve your outlook, and special vitamin supplements that target macular health may also help.

Additionally, Dr. K recommends eating a healthy diet, getting regular exercise, and quitting smoking. Protecting your eyes from UV light may also help. Although these lifestyle habits can’t reverse macula damage, they can slow the condition’s progression.

Depending on the type of macular degeneration you have, Dr. K may also recommend:

  • Anti-angiogenic drugs
  • Laser therapy
  • Photodynamic laser therapy
  • Submacular surgery
  • Vision rehabilitation
