- Diabetic eye disease comprises a group of eye conditions that affect people with diabetes. These conditions include diabetic retinopathy, diabetic macular edema (DME), cataract, and glaucoma.
- All forms of diabetic eye disease have the potential to cause severe vision loss and blindness.
- Diabetic retinopathy involves changes to retinal blood vessels that can cause them to bleed or leak fluid, distorting vision.
- Diabetic retinopathy is the most common cause of vision loss among people with diabetes and a leading cause of blindness among working-age adults.
- DME is a consequence of diabetic retinopathy that causes swelling in the area of the retina called the macula.
- Controlling diabetes—by taking medications as prescribed, staying physically active, and maintaining a healthy diet—can prevent or delay vision loss.
- Because diabetic retinopathy often goes unnoticed until vision loss occurs, people with diabetes should get a comprehensive dilated eye exam at least once a year.
- Early detection, timely treatment, and appropriate follow-up care of diabetic eye disease can protect against vision loss.
- Diabetic retinopathy can be treated with several therapies, used alone or in combination.
- NEI supports research to develop new therapies for diabetic retinopathy, and to compare the effectiveness of existing therapies for different patient group
