Pars plana vitrectomy in rhegmatogenous retinal detachment - a survey of 230 eyes

ABSTRACT

To evaluate the efficacy of pars plana vitrectomy [PPV] in treating patients with rhegmatogenous retinal detachment [RPD]. 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. 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 follow-up period was 9 +/- 7.2 [range 3-48]months. 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
