If you are experiencing blurred or reduced central vision due to retinal disease, the doctors of Retina Associates, P.A. in Shawnee Mission, KS, can customize a treatment plan that heals your eye and restores vision. Macular degeneration is classified as “wet” or “dry” depending on the underlying cause of vision loss. Our office can treat both forms of macular degeneration. 

What Is Dry Macular Degeneration?

Around 90 percent of people diagnosed with macular degeneration have the “dry” variant of the eye disease, according to the American Macular Degeneration Foundation. Dry macular degeneration results from the progressive thinning of the macula (the central area of the retina). 

As the photoreceptors and other important areas of the macula atrophy, the color of the macula begins to change. The thinning of the macular results in reduced function in most cases.

Symptoms of dry macular degeneration include:

  • Visual distortions
  • Difficulty seeing in low light situations
  • Reduced central vision
  • Difficulty reading printed words
  • Difficulty recognizing faces

Risk factors for dry macular degeneration include:

  • Advanced age (over 50)
  • Family history of retinal diseases
  • Tobacco use
  • Obesity
  • Cardiovascular disease

What Is Wet Macular Degeneration?

Around 10 percent of age-related macular degeneration is classified as “wet.” This form of macular degeneration typically progresses from the “dry” form. This condition results from the formation of new blood vessels in the choroid layer behind the retina.

The new vessels tend to be weak, which causes leaking and bleeding. Leaking fluids can cause scar tissue to form and retinal cells to cease functioning.

Symptoms of wet macular degeneration typically progress quickly and include:

  • Visual distortions
  • Impaired central vision
  • Reduced color perception
  • A general haziness in your overall vision

Risk factors for wet macular degeneration are the same for dry macular degeneration. 

What Are My Macular Degeneration Treatment Options?

Early diagnosis is critical for preventing vision loss. Macular degeneration is the leading cause of vision loss in individuals over the age of 60, according to the BrightFocus Foundation.

Diagnosis and Testing

There are a variety of diagnostic tests performed at our Shawnee Mission eye center that can look for signs of wet and dry macular degeneration. Once you have been diagnosed, possible forms of therapy can include medications, laser treatment, or implantation of a telescopic lens.

Learning to Live with Impaired Vision

Macular degeneration will not lead to substantial vision loss because peripheral vision is retained.

In some cases, a low vision rehabilitation specialist can help you find ways to adapt to your changing vision.

Early Treatment Can Save Your Vision

One of the best ways to stay ahead of wet or dry macular degeneration is to schedule regular eye exams, especially if you are over 50, have a family history of retinal diseases, or have not undergone an eye exam within the last year. To learn more, schedule a consultation at our Shawnee Mission practice. Contact us online anytime or give us a call at (913) 831-7400.
