Diabetic Retinopathy: Causes, Progression, and the Link Between Blood Sugar and Vision Loss
By
Rita Rastogi Kalyani, M.D., M.H.S.
Summary
Diabetic retinopathy is the leading cause of reversible blindness in the U.S., affecting about 40% of people with diabetes. The condition begins with swelling of tiny blood vessels in the eye, progresses to blockages that prevent blood and nutrients from reaching the retina, and in severe stages leads to abnormal new blood vessel growth. Uncontrolled blood sugar is the underlying driver of these eye complications.
