title: Early vitrectomy for severe proliferative diabetic retinopathy in eyes with useful vision. Clinical application of results of a randomized trial--Diabetic Retinopathy Vitrectomy Study Report 4. The Diabetic Retinopathy Vitrectomy Study Research Group.
abstract: Six patients are described, each of whom underwent early vitrectomy for advanced, active, proliferative diabetic retinopathy (PDR) in an eye with useful vision. These cases were selected to illustrate the spectrum of retinopathy severity for which early vitrectomy should be considered and the favorable outcome that can follow this procedure. None of the eyes that had an unfavorable result after early vitrectomy is presented. The eyes most suitable for early vitrectomy are those in which both fibrous proliferations and at least moderately severe new vessels are present, and in which extensive scatter photocoagulation has already been carried out or is precluded by vitreous hemorrhage.
