What You Should Know
Diabetic retinopathy (DR) is a common complication of diabetes.
DR progresses through 4 stages, mild nonproliferative retinopathy (microaneurysms), moderate nonproliferative retinopathy (blockage in some retinal vessels), severe nonproliferative retinopathy (more vessels are blocked leading to deprived retina from blood supply leading to growing new blood vessels), and proliferative retinopathy (most advanced stage). Diabetic retinopathy usually affects both eyes.
The risks of DR are reduced through disease management that includes good control of blood sugar, blood pressure, and lipid abnormalities. Early diagnosis of DR and timely treatment reduce the risk of vision loss; however, as many as 50% of patients are not getting their eyes examined or are diagnosed too late for treatment to be effective.
It is the leading cause of blindness among working-aged adults in the United States ages 20–74. An estimated 4.1 million and 899,000 Americans are affected by retinopathy and vision-threatening retinopathy, respectively. (courtesy of CDC).

Definition, Causes, Symptoms
Please visit the National Eye Institute website with patient information on diabetic retinopathy. The site is designed to help patients and their families search for general information about diabetic retinopathy. An eye care professional who has examined the patient's eyes and is familiar with his or her medical history is the best person to answer specific questions.
