Purpose: To evaluate the results and complications of pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR). Material and Methods: Sixty-five eyes of 53 patients with a mean age of 53.5±13.6 years who had undergone PPV for treatment of PDR complications were included in the study. In all eyes, posterior hyaloid and preretinal membranes were removed after standard PPV. Pre- and postoperative visual acuities, anterior and posterior segment findings, follow-up time and encountered complications were recorded. Results: Mean follow-up time was 13.6±9.2 months. Anatomical success was achieved in 94.4% of patients with vitreous hemorrhage, and in 83.3% of patients with fractional retinal detachment. Postoperatively, visual acuity improved in 81.5% of eyes, remained stable or decreased in 18.4% of eyes. The most common intraoperative complications were retinal microhemorrhages and formation of iatrogenic retinal breaks. Transient intraocular pressure (IOP) elevation and re-hemorrhages were the most common complications in the early and cataract formation in the late postoperative period. Conclusion: Pars plana vitrectomy is very effective in the treatment of PDR complications, but these patients should be closely followed up for possible complications
