Background  To compare the reoperation rate in patients with vitreous hemorrhage (VH) secondary to proliferative diabetic retinopathy (PDR) with or without preoperative intravitreal bevacizumab (IVB).    Methods  In this retrospective study, 280 patients (362 eyes) with diabetic VH were divided into a group that received preoperative IVB and a group that did not receive preoperative IVB. According to B-scan or color Doppler ultrasonography, the eyes were grouped as a VH group and a tractional retinal detachment (TRD) group. The reoperation rate, visual and anatomical outcomes of treatment were evaluated after 6 months.    Results  There were 17.4% of eyes in the VH group that did not receive preoperative IVB later required additional vitrectomy, while only 7.7% of the eyes in the VH group that received preoperative IVB required additional vitrectomy ( P  = 0.025). There were 45.5% of eyes in the TRD group that did not receive preoperative IVB had no reoperation, while only 21.4% of the eyes in the TRD group that received preoperative IVB had no reoperation ( P  = 0.004). The patients with one operation achieved better vision than those required reoperations in the VH group ( P  = 0.038) and TRD group ( P  = 0.019).    Conclusions  Preoperative IVB significantly reduced the re-vitrectomy rate in patients with VH without TRD, but there was an increase in the reoperation rate in patients with VH combined with TRD.
