Pars Plana Vitrectomy Versus Combined Pars Plana Vitrectomy-Scleral Buckle for Secondary Repair of Retinal Detachment

BACKGROUND AND OBJECTIVE: To investigate the optimal technique for repairing recurrent rhegmatogenous retinal detachments. PATIENTS AND METHODS: A 2-year retrospective review of recurrent rhegmatogenous retinal detachments by 23-gauge pars plana vitrectomy (PPV) or combined 23-gauge PPV with encircling scleral buckling was performed. The primary outcome was anatomical success. The secondary outcome was the likelihood of achieving a final best corrected visual acuity of 6/12 or better at 6-month follow-up. RESULTS: Anatomical success was achieved in 65.2% (95% CI, 53.4% to 75.4%) of the PPV group versus 74.3% (95% CI, 57.9% to 85.8%) of the PPV-scleral buckling group with one additional procedure (not statistically significant). There was no significant difference in the likelihood of achieving a final acuity of at least 6/12 between groups at 6-month follow-up. CONCLUSION: The results of our study do not demonstrate a superiority of method of primary repair, or of one method of secondary repair, over another.
