Pars Plana Vitrectomy in Rhegmatogenous Retinal Detachment - A Survey of 230 Eyes

Purpose: To evaluate the efficacy of pars plana vitrectomy (PPV) in treating patients with rhegmatogenous retinal detachment (RRD) Methods: In a retrospective study, we reviewed hospital records of patients with RRD operated by PPV at Farabi Eye Hospital between 2002 and 2004. The indications for PPV were proliferative vitreoretinopathy (PVR) grade B or C, holes posterior to the equator and holes greater than 90 degrees. Results: Two hundred and thirty patients were included in this study. The mean visual acuity improved from 2.6±0.61 logMAR to 2.1±0.77 logMAR after surgery (P=0.0001). The failure and redetachment rates after the first operation were 14.8% and 23.5%, respectively. In 202 of 230 eyes (87.8%), the retina was ultimately reattached with subsequent operations. The mean followup period was 9±7.2 (range: 3–48) months. Conclusion: Our outcomes are comparable with those of the previous studies and show that PPV is an effective procedure for most of the RRDs complicated by PVR.
