POSTERIOR VITREOUS DETACHMENT STATUS AS A PREDICTIVE FACTOR FOR OUTCOMES OF VITRECTOMY FOR DIABETIC VITREOUS HEMORRHAGE.

Purpose: The purpose of this study was to evaluate the prognostic utility of the degree of vitreous attachment for predicting outcomes of vitrectomy for nonclearing vitreous hemorrhage associated with proliferative diabetic retinopathy.

Methods: Medical records of patients who underwent primary vitrectomy for dense nonclearing vitreous hemorrhage secondary to proliferative diabetic retinopathy were examined retrospectively. Eyes were divided into four groups based on the intraoperatively assessed stage of posterior vitreous detachment (PVD), ranging from Stage 0/1 (complete or near-complete vitreoretinal adhesion) to Stage 4 (complete PVD).
