We performed vitreous surgery for proliferative diabetic retinopathy in 92 eyes 56 months through 1990. We reviewed the visual outcome in 62 eyes, 55 cases, who could be followed up for one year or longer. A life table analysis by Kaplan-Meire was used in the evaluation. The series comprised 40 eyes which were operated for vitreous hemorrhage persisting for 6 months or more (group 1) and 22 eyes with tractional retinal detachment involving the macula (group 2).

Reattachment of the retina was achieved in 55 eyes, 89%. The final visual acuity improved in 83% of eyes in group 1 and in 32% of eyes in group 2, average 52% in both groups. Visual improvement in group 1 resulted in 90% at 1 month after surgery and in 68% at 18 months. Visual improvement in group 2 resulted in 55% at 1 month and 32% at 12 months. The differences between the two groups were significant (p <0.05). Out of 32 eyes with postoperative visual improvement, 4 eyes showed gradual late decrease in vision, either due to diabetic maculopathy, cataract or epimacular membrane.
