Purpose To evaluate the outcomes of epiretinal membrane (ERM) surgery in highly myopic eyes without traction maculopathy, and to compare them with those from non–highly myopic eyes. Design Retrospective nested case-control study from a cohort of 509 consecutive patients (509 eyes) who underwent pars plana vitrectomy with ERM removal. Methods Thirty-two highly myopic eyes (with a refractive error of more than −6.00 diopters [D]), which underwent surgery for isolated ERM, were included in the study. For each case studied, we selected from the same cohort 2 age-matched controls who had ERM surgery (n = 64 non–highly myopic eyes). The best-corrected visual acuity (BCVA), the central macular thickness (CMT), and the surgical complications were analyzed. Results The mean follow-up duration was 3.2 ± 1.5 years for the study cases and 3.4 ± 1.6 years for the control group ( P  = .608). At the final follow-up examination, the mean logMAR BCVA had improved significantly, from 0.56 to 0.26 ( P < .001) for the case group and from 0.54 to 0.22 ( P < .001) for the control group. At the final optical coherence tomography (OCT), the mean CMT had improved significantly, from 433 to 314 μm ( P < .001) for the case group and from 428 to 303 μm ( P < .001) for the control group. There was no significant difference between the 2 groups as regards visual or CMT improvement ( P  = .526 and P  = .483, respectively). The incidence of surgical complications was not significant between the 2 groups. Conclusions The results of ERM surgery were not different in terms of anatomic and visual outcomes and surgical complication between highly myopic and non–highly myopic eyes.
