Abstract
This review compares 23-gauge pars plana vitrectomy (PPV) alone versus combined 23-gauge pars plana vitrectomy and scleral buckle (PPV/SB) for primary repair of pseudophakic rhegmatogenous retinal detachment (RRD). A retrospective review of 70 eyes that underwent 23-gauge PPV and 43 eyes that received 23-gauge PPV/SB for pseudophakic RRD. Minimum follow-up was 3 months. Outcome measures included anatomical success, visual acuity, and complication rates. The 23-gauge PPV group achieved primary anatomical success in 58 of 70 cases (83%). Primary success in the PPV/SB group occurred in 36 of 43 cases (84%). Final anatomical success was achieved in all 113 cases (100%). The difference in primary success rates was not statistically significant (P = 1.000, Fisher exact test). Average visual acuity for macula-on RRDs in the PPV group showed a +0.07 logMAR improvement (P = .580) versus a +1.34 improvement (P < .001) in macula-off PPV cases. SB/PPV macula-on cases showed a decrease in logMAR visual acuity by -0.06 (P = .380) while macula-off SB/PPV cases improved by +1.28 (P = .002). There were no significant complications in either group. Both 23-gauge PPV and PPV/SB are effective procedures for repairing pseudophakic RRD and exhibit similar rates of success.
