Diabetic vitrectomy.

Abstract

Proliferative diabetic retinopathy is one of the leading causes of permanent vision loss. Vitrectomy for the complications of proliferative changes has resulted in preservation of vision. Recent studies have focused on the cellular and structural changes in patients with proliferative changes. Data obtained from the early Treatment of Diabetic Retinopathy Study show that the rate of vitrectomy is reduced in eyes that have early-scatter photocoagulation in comparison with those that have deferral of treatment. The efficacy and complications of silicone oil tamponade have been more carefully evaluated with respect to complex detachments associated with proliferative diabetic retinopathy.
