What is the most common cause of blindness in diabetic patients?

Neovascularization
Macular edema
Cataracts
Glaucoma

Explanation

Answer: B. - Macular edema is the most common cause of blindness in diabetic patients.

Macular edema occurs when diffuse capillary and microaneurysm leakage at the macula causes the macular retina to swell with fluid. Upon exam, the macula looks cloudy and mildly elevated, and past evidence of edema in the form of yellow-colored, hard exudates can be seen.
