PURPOSE
To evaluate the efficacy of preoperative intravitreal bevacizumab (Avastin(R); Genetech, San Francisco, CA, USA) injections of pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR). METHODS: Thirty patients (30 eyes) who underwent PPV for treatment of PDR and received a preoperative intravitreal bevacizumab injection of 1.25 mg were retrospectively analyzed. The study group (group 1, 30 patients, 30 eyes) was compared with a control group (group 2, 29 patients, 30 eyes and matched with the study group for preoperative parameters) who underwent PPV without preoperative intravitreal bevacizumab injection. RESULTS: In both groups, visual acuity improved but there was no statistical significance. Intraoperative vitreous hemorrhage occurred in 14 eyes (46.7%) from group 1 and 11 eyes (36.7%) from group 2. There was no statistical significance of intraoperative bleeding occurrence (p=0.3). Postoperative vitreous hemorrhage occurred in 4 eyes from group 1 and 14 eyes from group 2. The group 1 had a lower incidence of postoperative hemorrhage than group 2 (p=0.005). CONCLUSIONS: Preoperative intravitreal bevacizumab injection appears effective in decreasing early postoperative vitreous hemorrhage and maybe technically helpful in PPV for PDR. |
