To investigate the clinical features and surgical outcomes in patients with epiretinal membrane–induced full-thickness macular holes (FTMHs).Methods:
Consecutive cases with epiretinal membrane–induced FTMH followed by a single surgeon were retrospectively reviewed (study group, 24 cases). The criteria of epiretinal membrane–induced FTMH selection were 1) documented lamellar macular hole before FTMH formation, 2) FTMH with lamellar hole–associated epiretinal proliferation at the hole edge, and 3) FTMH with wider inner opening and narrower base. Consecutively treated Stage 2 (Control A, 20 cases) and Stage 4 (Control B, 22 cases) MH patients served as controls. All patients were followed up for at least 12 months after treatment.Results:
Patients in the study group were younger and had a higher rate of high myopia than Controls A and B. The average hole size (203.6 ± 104.9 μm) was similar to that in Control A group and smaller than that in Control B group; the postoperative visual improvement (2–3 lines in Early Treatment Diabetic Retinopathy Study) was lower than that in Control A and B groups. Similar results were found when excluding high myopia cases from the study group.Conclusion:
Epiretinal membrane–induced FTMH has distinct features from the typical Stage 2 or 4 FTMH. Despite the small size, visual improvement is not as good as that in Stage 2 FTMH.
