Overview
Brief Summary
The most common ocular disease in patients with diabetes, diabetic retinopathy, is present in approximately 40% of diabetic patients; about 8% of diabetic patients have vision threatening diabetic retinopathy. Although intensive control of blood glucose has been shown to reduce the development and progression of diabetic retinopathy, intensive control of glucose is usually not achieved in clinical practice.
