Surgical outcomes of Pars Plana Vitrectomy for recurrent retinal detachment in eyes previously treated with Pars Plana Vitrectomy or Scleral Buckling

Abstract

To report anatomical and functional outcomes of pars plana vitrectomy (PPV) for recurrent retinal detachment (RD) after failed scleral buckling (SB) or primary PPV. Retrospective analysis of 59 eyes with recurrent RD treated previously with SB or PPV was performed. All eyes underwent 23 gauge PPV. The primary outcome was single surgery success rate (SSSR) for retinal reattachment at the final visit. Secondary outcomes were visual acuity change and number of reoperations. SSSR was 77.4% in the SB group and 67.9% in the PPV group (P=0.41). The mean change in visual acuity was not significantly different between the two groups (P=0.35). The mean number of reoperations was 1.2±0.5 and 1.4±0.6 in the SB and PPV groups, respectively (P=0.38). PPV was found to be an effective technique for the management of recurrent RD after SB and PPV surgeries. However, the small sample size and the retrospective design prevent any claims of advantages or disadvantages of one surgical technique over the other.
