    Abstract:
    PURPOSE: To investigate the anatomical success rates of scleral buckling (SB) and pars plana vitrectomy (PPV) performed for rhegmatogenous retinal detachment (RRD) in a large case series and to identify prognostic factors for the primary anatomical success rates of surgical techniques. METHODS: We reviewed 542 consecutive eyes for primary RRD in this retrospective study. Follow-ups were performed for at least six months. In each of the two groups, 271 eyes were examined. The main outcome measure was the primary anatomical success rate. Multivariate analysis was also performed to determine whether independent risk factors of the preoperative parameters for redetachment exist. RESULTS: The primary anatomical success rates were 93.7% and 96.3% in the SB and PPV groups; and the final anatomical success rates were 100% in both groups (each with 271 eyes). In the SB group, eyes with macula-off had significantly lower primary anatomical success rates than those with macula-on (p = 0.002). Preoperative break location or lens status had no significant effect on primary anatomical success rates in either group. Multivariate logistic regression analysis using four variables, namely, sex, posterior vitreous detachment, macular status and preoperative visual acuity, showed that the macular status was an independent risk factor for redetachment in the SB group (p = 0.039, odds ratio 3.7). The six-month follow-up visual acuity was significantly better than the preoperative visual acuity in both groups (p ≤ 0.001). CONCLUSIONS: Both SB and PPV gave excellent primary and final anatomical success rates. The macula-off status was associated with a lower success rate in the SB group, although break location and lens status had no significant effect on success rates in either group.
