Epiretinal Membrane Surgery After Retinal Detachment Repair: Visual Acuity Outcomes and Optical Coherence Tomography Analysis.
2021
Abstract Purpose To assess visual acuity (VA) outcomes of epiretinal membrane (ERM) surgery following primary rhegmatogenous retinal detachment (RD) repair. Design Retrospective, consecutive case series. Subjects Eyes undergoing pars plana vitrectomy (PPV) with membrane peel (MP) surgery for ERM following primary RD repair (PPV with or without scleral buckle (SB) and gas tamponade). Methods Retrospective chart review from 2015 to 2018. A previously described ERM grading scale was utilized for OCT structural analysis. Main outcome measures Visual acuity (VA) and change in VA at 6 months and final follow-up. Secondary outcomes included assessment of structural OCT features predictive of VA outcomes. Results 53 eyes of 53 patients were included. VA improved significantly from logMAR 1.00 ± 0.51 (Snellen 20/200) pre-MP to 0.45 ± 0.41 (20/56) at 6 months and 0.42 ± 0.41 (20/53) at final follow-up, a significant improvement (p Conclusions Eyes undergoing MP after RD repair have significant VA gains independent of macula-status at time of RD repair. Pre-operative ellipsoid zone disruption was the OCT feature best predictive of VA.
