What does diabetic retinopathy affect?

• A. Blood vessels in the retina
• B. The optic nerve
• C. The cornea of the eye
• D. The lens of the eye

Answer: (A)

Diabetic retinopathy specifically affects the blood vessels in the retina. This condition is a diabetic complication that results from prolonged high blood sugar levels damaging the retinal blood vessels. As these vessels become weakened or blocked, it can lead to bleeding, leakage of fluid, and abnormal growth of new blood vessels, which can severely impair vision. Understanding that diabetic retinopathy is primarily concerned with the health and integrity of these blood vessels helps in recognizing its potential impact on sight and the importance of early detection and management in individuals with diabetes.
