title: [The efficacy of vitrectomy in severe complicated proliferating diabetic retinopathy].
abstract: Vitrectomy was made in 69 patients (71 eyes) with proliferative retinopathy complicated by hemorrhage into the vitreous body. In most cases (90.1%), visual acuity didn't exceed 0.05. To prevent possible complications at the time of operation and in the postoperative period preliminary cryocoagulation before vitrectomy was made in a part of the patients (47 patients, 49 eyes). Comparative analysis of results after vitrectomy with and without cryocoagulation has shown that the incidence of operative complications was remarkably lower, than in the first group of patients. Hemorrhage into the vitreous body was observed in combined intervention in 4.0%, and in vitrectomy without preliminary intervention--in 22.7% of cases. Restoration of transparency of the vitreous body was recorded to be more frequent in group I (48.9% against 35.2%). In remote terms, visual acuity improved in 85.7% in group I, and in 45.5%--in group II. Vitrectomy with preliminary cryocoagulation is indicated to all patients with complicated far-advanced proliferative diabetic retinopathy.
