If you are living with diabetes, there are a lot of things you need to be aware of and monitor closely to avoid complications. This includes your eyes, which are at risk of an eye disease called diabetic macular edema (DME) if you have type 1 or type 2 diabetes.
What is diabetic macular edema?
DME is a condition in which fluid builds up in the macula, the center of the eye’s retina, according to the National Eye Institute. “This part of your retina is essential for reading, driving, and seeing people’s faces,” Lee M. Jampol, MD, an ophthalmologist at Northwestern Memorial Hospital and professor of ophthalmology at Northwestern University’s Feinberg School of Medicine in Chicago tells Everyday Health.
One side effect of living with diabetes is that it weakens the blood throughout your body, and your eyes aren’t exempt from this.
“It’s like a leaky pipe that drips on ceiling tiles,” Sunir Garg, MD, a clinical spokesperson for the American Academy of Ophthalmology (AAO) and professor of ophthalmology at Wills Eye Hospital in Philadelphia shares with Everyday Health.“Eventually, the tiles will rot and fall apart.” Similarly, this fluid leakage in the eye causes the macula to become swollen, which can harm your vision.
The key to protecting your eyes before DME develops or catching it early is to see an ophthalmologist regularly, especially if you have diabetes. An ophthalmologist can detect DME via an eye exam. This is important because when left untreated, DME can lead to temporary— or even possibly permanent — loss of central vision, according to Dr. Jampol.
If you do have DME, the good news is that there are several options for treatment:
Injectable drugs
Anti-VEGF (vascular endothelial growth factor) injections work by slowing down blood vessel growth and stopping fluid leaks and are the gold standard for treating DME, Jampol tells Everyday Health.
“As soon as they became available 10 or 12 years ago, it was clear they were the best treatment for DME,” he says.
Anti-VEGF injections are administered through a thin needle. Your doctor will give you a few numbing drops in your
