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.

Of the more than 38.4 million Americans who have diabetes, as many as 1 in 15 eventually develop DME, according to the National Eye Institute (NEI).

“[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.

After developing DME, you may have trouble reading books (the letters can appear twisted or misshapen) or seeing the faces of friends and family. Vision loss can have a serious impact on your quality of life. It can limit your ability to drive, manage finances, and travel. Plus, people who are visually impaired are more likely to have depression and experience a fall than those who don’t have low vision, notes the Centers for Disease Control and Prevention (CDC).

According to the CDC, vision loss is a cause of disability and a public health problem in the United States.

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)?

Calvin W. Roberts, MD, an ophthalmologist and clinical professor at Weill Cornell Medical College, explains if there are ways to slow the progression of diabetic macular edema.

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.

According to the CDC, the goal for most people with diabetes should be an A1C of less than 7 percent, but individual goals will depend on factors such as age and other health conditions you may have. So you should talk to your doctor about the A1C goal that’s right for you.

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.

One review found that compared with aerobic or resistance exercise alone, a combination of the two was the best method to improve blood sugar, insulin levels, and other health factors, such as weight, blood pressure, cholesterol and triglycerides.

 And another review found that combining aerobic and resistance training showed signs of improved glucose (blood sugar) metabolism and reduced inflammation in sedentary adults without diabetes.

The U.S. Department of Health and Human Services’ Office of Disease Prevention and Health Promotion recommends that adults shoot for at least 150 minutes of moderate-to-vigorous physical activity and two days of weight training per week.

 That said, it’s important to talk to your doctor before starting any exercise if you have DME. According to the American Diabetes Association (ADA), if you have retinopathy, it’s important to use caution when considering certain strenuous exercises, such as ones that require heavy lifting and straining, as well as high-impact activities that cause jarring or bending your head down.

4. Eat a Healthy Diet

When it comes to maintaining or lowering your blood sugar levels, it’s hard to overstate the importance of a healthy diet. The ADA recommends a diet full of dark green leafy vegetables, nuts, seeds, fish high in omega-3 fatty acids, and other healthy fare.

5. Stop Smoking

Research on the effect of smoking on diabetic retinopathy has yielded conflicting results. Some studies found that smoking increased the risk of diabetic retinopathy, while others showed that it had no effect on — or even protected against — diabetic retinopathy. One study has shown that a history of smoking is associated with changes in the retina that are linked to the development of diabetic retinopathy.

Moreover, tobacco increases the amount of sugar in your blood and weakens the blood vessels in your eyes. Both are good reasons to stop smoking, particularly if you want to reduce your risk of DME or help slow progression of the disease, according to Mayo Clinic.

And eye health is by no means the only reason to stop smoking if you have diabetes. According to the CDC, smokers who have diabetes are more likely than nonsmokers with diabetes to have heart disease, kidney disease, peripheral neuropathy, and retinopathy. For help quitting, call 1-800-QUIT-NOW.

6. Get Your Cholesterol and Blood Pressure Levels Under Control

According to research, high blood pressure and cholesterol levels may increase your risk of developing DME or of the eye condition progressing (if you already have DME). The American Heart Association defines healthy blood pressure as below 120/80. Talk to your doctor about your target cholesterol levels.

7. Use Low-Vision Aids

If you have DME, using low-vision aids, such as magnifying devices and telescopic eyeglasses, can help maximize your vision, according to the CDC. And low-vision devices not only improve your quality of life, but can also keep you safe and help you maintain your independence.
