What ocular finding is commonly associated with diabetes and can lead to vision impairment if untreated?

• A. Diabetic retinopathy (often with macular edema)
• B. Cataracts
• C. Glaucoma
• D. Retinitis pigmentosa

Answer: (A)

Diabetic retinopathy is the eye finding most directly linked to diabetes. Prolonged high blood sugar damages the tiny vessels in the retina, leading to microaneurysms, blot-like hemorrhages, and hard exudates. When fluid leaks into the central retina, macular edema develops, causing blurry or distorted vision and is a major reason why vision declines in diabetes if not treated. As it progresses, new but fragile blood vessels grow on the retina; these can bleed or form scar tissue that pulls on the retina, worsening vision and potentially causing severe vision loss. While cataracts or glaucoma can occur with diabetes, they are not as specifically tied to the disease as the retinal vascular changes are. Retinitis pigmentosa is an inherited condition unrelated to diabetes.
