High speed vitrectomy in the treatment of proliferative diabetic retinopathy

Abstract

Objective To evaluate the efficacy and benefit of high speed pars plana vitrectomy (PPV) in the treatment of proliferative diabetic retinopathy (PDR).Methods Eighty-six patients (86 eyes) with PDR were randomized into 2 groups and all were treated with PPV.The speed of vitrectomy was 750c/min in group A,and 1200-1500c/min in group B.pre-and postoperative best-corrected visual acuity (BCVA) and dilated fun- dus were examined,and the data were analyzed.Results The complication and silicone oil rate of group B was fewer than group A,and the visual function evaluation of group B was better than group A,the surgery time of group B was obviously shorter than group A (from 1.2hr in group A to 48.2 min in Group B).Conclu-sions The high speed PPV could reduce the complications such as the iatrogenic teals,tractional retinal de- tachment and vitreous hemorrhage.
