Abstract

Abstract : Purpose: To identify factors associated with persistent subretinal fluid (SRF) after small-gauge pars plana vitrectomy for primary rhegmatogenous retinal detachment. Methods: This retrospective study included patients from 2 tertiary centers who underwent pars plana vitrectomy for repair of rhegmatogenous retinal detachment between 2013 and 2016. Preoperative and intraoperative parameters were examined for association with development of SRF. Results: Overall, 153 eyes of 153 patients, mean age of 55.2 ± 17.9 years were included. Persistent SRF occurred in 15.0% (n = 23) and was associated with high myopia (65.22 vs. 26.15%, P < 0.001), macula-involving retinal detachment (91.30 vs. 66.15%, P = 0.02), phakic lens status (86.96 vs. 66.15%, P = 0.04), and younger age (47.8 ± 18.7 vs. 56.5 ± 17.5, P = 0.04) while drainage retinotomy was protective (13.04 vs. 34.11%, P = 0.04). In multivariate analysis, high myopia ( P = 0.009) and macula-involving retinal detachment ( P = 0.004) were associated with SRF, while drainage retinotomy was protective ( P = 0.03). Persistent SRF was associated with outer retinal band irregularity (30.4 vs. 9.3%, P = 0.005). There were no significant differences in terms of change in best-corrected visual acuity from presentation ( P = 0.70), or final best-corrected visual acuity ( P = 0.54). Conclusion: Eyes with preoperative high myopia and macular involvement, and those in which a drainage retinotomy was not performed, were more likely to develop persistent SRF. Abstract : Supplemental Digital Content is Available in the Text.In this retrospective cohort study of 153 patients, the incidence and risk factors for persistent subretinal fluid after small-gauge vitrectomy were assessed. Fifteen percent of eyes developed persistent subretinal fluid and associated factors identified were preoperative high myopia, macular involvement, and no drainage retinotomy performed during surgery.
