Purpose: To demonstrate the effects of epiretinal membrane (ERM) and epiretinal proliferation on surgical outcomes for full-thickness macular hole. Methods: Nested case–control study with propensity score matching. Patients operated on for full-thickness macular hole between January 2011 and March 2020 were enrolled. The primary outcome was failure of the macular hole closure, and the secondary outcome was unfavorable hole closure (V or l type closure) at 6 months after the surgery. Results: Five hundred and thirty-four eyes of 534 patients met the inclusion criteria. After 1:1 propensity score matching (127 pairs), patients demonstrating ERM were more likely to have a failure of hole closure (adjusted odds ratio, 2.71; 95% confidence interval, 1.19–6.14) and unfavorable hole closure (adjusted odds ratio, 2.07; 95% confidence interval, 1.16–3.71). Epiretinal membrane spanning the hole margin (hole marginal ERM) greatly increased the likelihood of unfavorable hole closure (adjusted odds ratio, 2.13; 95% confidence interval, 1.12–4.07). Patients with hole marginal-ERM + epiretinal proliferation were more likely to have a failure of hole closure (38.4%) compared with those with no ERM (11.8%). Conclusion: Patients with ERM had a higher risk for adverse surgical outcomes for full-thickness macular hole closure. The location of the ERM relative to the macular hole and the presence of epiretinal proliferation might affect the surgical outcomes for full-thickness macular hole closure.
