Introduction: This study aimed to investigate the incidence of and risk factors for epiretinal membrane (ERM) formation following primary rhegmatogenous retinal detachment (RRD) repair. Methods: This comparative, retrospective, single-center cohort study included eyes with primary RRD treated between 2011 and 2023 at Massachusetts Eye and Ear, Boston, Massachusetts, with pars plana vitrectomy (PPV), scleral buckle (SB), PPV+SB, or pneumatic retinopexy (PnR). Demographic, clinical, and surgical parameters were collected from medical records. The primary outcome was the risk of ERM formation, while the secondary outcome was the risk of ERM requiring surgery. Univariable and multivariable Cox regression were performed, and a hazard ratio (HR) and 95% confidence interval (95% CI) were reported. Results: Overall, 394 eyes were included. The mean age was 58.49 ± 12.8 years, and most patients were male. There was a significantly lower risk of ERM formation following SB compared to PPV in the univariable analysis (HR = 0.2, 95% CI = 0.08–0.60, p = 0.003); however, there was no significant association between treatment modality and ERM formation on multivariable Cox regression controlling for confounding factors (p = 0.24). ERM formation was found more commonly in patients who were older (HR = 1.0 per 1 year increase in age, 95% CI = 1.01–1.04, p = 0.001), those with worse baseline visual acuity (HR = 1.3, 95% CI = 1.09–1.71, p = 0.008), and those with macula-off RRDs (HR = 2.1, 95% CI = 1.41–3.32, p < 0.001). Conclusion: Surgical modality does not have a significant impact on the risk of ERM following retinal detachment repair. However, age, baseline visual acuity, and macular status are important predictors of ERM formation after RRD repair.
