7 Ways to Slow the Progression of Diabetic Macular Edema

Diabetic macular edema (DME) is caused by diabetic retinopathy, a complication of diabetes that leads to swelling of the macula, a small but important area in the back of your eye that helps you see what’s in front of you clearly.
“[The macula] is the center of the retina, where you have the best vision,” says Daniel S. Casper, MD, PhD, a professor emeritus of ophthalmology at Columbia University Irving Medical Center in New York City. It’s the part of the eye that helps you see straight ahead, he adds.
If you have DME, it’s important not to delay treatment. By trying these 7 strategies — on top of getting medical treatment — it’s possible to prevent further vision loss. Follow this sight-saving advice.
Are There Ways to Slow the Progression of Diabetic Macular Edema (DME)?

1. Lower Your Blood Sugar Levels
If you have DME, having high blood sugar can increase your risk of blindness, according to the NEI. Dr. Casper tells people to try to lower their A1C number — a measurement of your average blood sugar levels over the past three months — to under 7 percent.
2. Schedule Regular Eye Appointments
People with diabetes are often advised to see an eye doctor annually. After a diabetic macular edema diagnosis, you may need to go more frequently, depending on the progression of the disease and the status of your A1C.
If your A1C is too high and you have certain lifestyle habits, such as smoking, that speed up symptom progression, then you may need to schedule a checkup once every few months, says Casper.

3. Exercise Regularly
Staying active can help improve your all-important A1C level, and the best way to lower your blood sugar and improve insulin sensitivity is by doing a combination of aerobic and resistance exercise.
4. Eat a Healthy Diet
5. Stop Smoking
6. Get Your Cholesterol and Blood Pressure Levels Under Control
7. Use Low-Vision Aids

He earned his medical degree from Dartmouth. He completed an ophthalmology residency at the NYU Grossman School of Medicine, where he was chief resident, followed by a fellowship in uveitis and ocular inflammatory disease at the Francis I. Proctor Foundation for Research in Ophthalmology at the University of California in San Francisco.
Dr. Tsui is committed to advancing the field of ophthalmology. His research focuses on utilizing state-of-the-art ophthalmic imaging technology to improve the diagnosis and monitoring of uveitis. He is a co-investigator in several multicenter clinical trials investigating therapeutics for uveitis. He is the author of over 80 peer-reviewed publications and has given talks at national and international conferences.
Along with his clinical and research responsibilities, Tsui teaches medical students and residents. He is on the Association for Research in Vision and Ophthalmology's professional development and education committee, as well as the advocacy and outreach committee, which seeks to increase funding and awareness of vision research. He also serves on the editorial board of Ophthalmology and the executive committee of the American Uveitis Society.
