Which condition is a form of vascular retinopathy associated with diabetes?

• A. Glaucoma
• B. Iritis
• C. Diabetic retinopathy
• D. Presbyopia

Answer: (C)

Vascular retinopathy refers to damage to the retinal blood vessels caused by conditions that affect small vessels, with diabetes being a classic cause. Chronic high blood sugar injures the tiny retinal vessels, leading to changes like microaneurysms, hemorrhages, and in more advanced stages, new abnormal vessel growth. This retinal vascular disease is known as diabetic retinopathy, a common complication of diabetes that can threaten vision if not managed.

The other options describe different eye problems: glaucoma is optic nerve damage related to intraocular pressure, iritis is inflammation of the iris, and presbyopia is an age-related loss of near focusing. Therefore, the condition associated with diabetes is diabetic retinopathy.
