Representative cases with epiretinal membrane (ERM) and concurrent open-angle glaucoma in each group. In the peeling group, a 67-year-old male underwent ERM removal with a vitrectomy in the right eye. His visual acuity (VA) was increased from 0.2 to 0.6. His mean deviation (MD) worsened from − 9.80 dB to − 11.65 dB. The ERM and ILM were removed completely without recurrence, and microcystic macular edema (MME) improved. In the observation Group, a 64-year-old woman was observed without vitrectomy over the follow-up period. VA in her left eye worsened from 1.2 to 0.8, with an expansion of the central visual field defect. Her MD changed from − 15.72 dB to −15.33 dB. The ERM and MME were not resolved.
