DME: What to Expect

Diabetic macular edema (DME) is a complication of diabetes that affects the eyes. It occurs when poorly controlled blood sugar damages the small blood vessels in the retina, causing fluid to leak into the macula. This part of the eye is responsible for sharp, straight-ahead vision. About 10% of people with diabetes develop DME.

DME doesn't always cause symptoms, but you may have blurry vision, seeing double, and a sudden increase in eye floaters. 

If you've been diagnosed with DME, there's a lot you can do to keep your condition from getting worse. First, manage your diabetes by controlling your blood sugar. High blood sugar over time can damage blood vessels in your eyes. 

Diet changes can help keep your eyes as healthy as possible. The "plate method" is a helpful guide: half your plate should be fruits and vegetables, a quarter should be whole grains, and the remaining quarter should be protein.

Aim for at least 150 minutes of moderate exercise per week. Activities like walking, biking, and water aerobics increase blood flow to the retina, supporting eye health. Talk to your doctor before starting a new exercise regimen.

High blood pressure can worsen DME. Manage your blood pressure by limiting alcohol, exercising regularly, reducing stress, and losing weight. Even a small amount of weight loss can make a difference. 

If you notice your vision getting worse, or have other symptoms you're worried about, contact your doctor right away. Managing your diabetes and staying on top of any changes can help preserve your eyesight.
