Macular Degeneration

Have you noticed your vision worsening with age?

Central vision loss could be a sign of macular degeneration.

The board-certified doctors at Ohio Vision in Sidney, OH, can help you detect and manage the symptoms of this eye disease.

What Is Macular Degeneration?

The macula is the center of the retina. When the macula starts to deteriorate, the eye's central vision worsens. Macular degeneration can make it difficult for patients to see and process information in their central field of vision.  

Symptoms of Macular Degeneration

  • Central vision loss
  • Straight lines appearing crooked
  • Needing more light to read
  • Changes in color perception
  • Changes in vision quality
  • Trouble adapting to low light levels

Macular Degeneration Risk Factors

Advanced Age

Patients age 55 and older have a greater chance of developing age-related macular degeneration. The older someone is, the greater the chance they have AMD. 


A 2010 study found that white Americans had a greater likelihood of developing AMD. 2.5% of white adults over 50 develop AMD, compared to 0.9% each of blacks, Hispanics, and Americans of other races. 

Family History

As with many medical conditions, a family history of the disease can increase your chances of developing age-related macular degeneration.

History of Smoking

According to the Macular Society, smokers are up to four times more likely to have AMD than nonsmokers. Also, smokers have an increased risk of developing AMD 10 years earlier than nonsmokers.


A high BMI can increase your risk of developing age-related macular degeneration, but improving your health can slow down progression of this eye disease.

Heart Disease

Patients who have suffered a heart attack or stroke have a greater chance of developing age-related macular degeneration.

Diabetic Patients

Patients with either type I or type II diabetes are at a greater risk of developing macular degeneration.

Are You At Risk? Request a Consultation

If you have any of the risk factors listed above, regular eye exams are crucial to spotting age-related macular degeneration and slowing the progression of the disease.

The office staff were great! Very helpful with insurance and what to expect coming in. Dr. Wilding is very comforting and fun to be around. For my procedure he was very good with explaining what he was doing and what to expect. He has a very good "bnedside manner"!

Daily Eye Exams A Simple Way to Monitor for AMD

Patients experience gradual vision loss with age-related macular degeneration. This slow-paced vision loss can be hard to notice in its earliest stages. If you're at risk for dry AMD, check your vision daily with the Amsler grid to pinpoint vision changes. Here's how to use this simple yet effective tool:
Take the Amsler grid test once a day, every day, to notice any vision loss.
Take the Amsler grid test once a day, every day, to notice any vision loss.

Print the Grid

The Amsler grid is free to print online. Print it out on a standard sheet of paper to mark any changes.

Look at the Grid

Hold the grid about a foot away from your eyes. Cover one eye and look at the center dot. If you have glasses, leave them on during the test and ensure you have good lighting.

Note Distorted Vision

As you look at the center dot, take note of the grid lines in your peripheral vision. If any lines look wavy, blurry, or dark, take note on the sheet of paper. Repeat with your other eye.

Contact Our Team

When you notice these distortions in your field of vision, it's time to contact our team and head to our Sidney office, or one of our other locations, for a comprehensive eye exam.
