Comparison the Results of Pars Plana Vitrectomy (PPV) With and Without an Encircling Scleral Band (SB) for the Repair of Primary Rhegmatogenous Retinal Detachment

Purpose: To compare the results of pars plana vitrectomy (PPV) with and without an encircling scleral band (SB) for the repair of primary rhegmatogenous retinal detachment (RRD). Methods: We reviewed the records of 49 patients who underwent PPV and combined vitrectomy plus SB for primary RRD. The minimum follow-up time was 6 months. There were 25 eyes in the PPV group and 24 eyes in the PPV plus SB group. Anatomic success, baseline and final best-corrected visual acuity (BCVA),and complications were evaluated. Results: Mean follow-up was 15.2±8.1 months and 15.5±9.4 months in the PPV group and PPV plus SB group, respectively. The anatomical success rate after a single operation was 96.0% in the PPV group and 95.8% in the PPV plus SB groups (P=0.33). Final BCVA was 0.90±0.72 logMAR in the PPV group and 0.80±0.74 logMAR in the PPV plus SB group (P=0.38).The visual gain was similar in both groups (P=0.76). Glaucoma was recorded in both cases in each group. Endophthalmitis was not recorded in any group. Conclusion: The final BCVA, rate of anatomic success and complications were similar in the PPV and PPV plus SB groups. Addition of SB to perform a 23-gauge PPV had no significant effect on the outcomes of RRD.
