Diabetic retinopathy is a common complication of diabetes. High blood sugar damages the blood vessels in the retina (a light-sensitive part of the eye), where scarring can cause permanent vision loss.
Diabetic retinopathy is also one of the most preventable causes of vision loss and blindness. Early detection and treatment can prevent or delay blindness due to diabetic retinopathy in 90% of people with diabetes, but 50% or more of them don’t get their eyes examined or are diagnosed too late for effective treatment.
People with diabetes are also at higher risk for other eye diseases, including glaucoma and cataracts. If you have diabetes, an eye exam every year is necessary to protect and preserve your eyesight and eye health.
