AbstractWe investigated the impact of drainage retinotomy on the outcome of pars plana vitrectomy for repair of rhegmatogenous retinal detachment (RRD). This study was a retrospective observational multicenter study. All patients were registered with the Japan-Retinal Detachment Registry. We analyzed 1887 eyes with RRD that had undergone vitrectomy and were observed for 6 months between February 2016 and March 2017. We compared the baseline characteristics and postoperative outcomes between eyes with and without drainage retinectomy. We then performed propensity score matching using preoperative findings as covariates to adjust for relevant confounders. Of 3446 eyes, 1887 met the inclusion criteria. Among them, 559 eyes underwent vitrectomy with drainage retinotomy, and 1328 eyes underwent vitrectomy without drainage retinotomy. After propensity score matching, each group comprised 544 eyes. There was no significant difference between the two groups in BCVA at 6 months after vitrectomy (0.181 vs. 0.166, P = 0.23), the primary anatomical success rate (6.3% vs. 4.4%, P = 0.22), or the rate of secondary surgery for ERM within 6 months (1.5% vs. 1.3%, P = 1.0). Drainage retinectomy does not increase the risk of decreased postoperative BCVA, surgical failure, or secondary surgery for ERM within six months outcomes.
