Abstract
PURPOSE: To compare the surgical outcomes of epiretinal membranes (ERMs) associated with retinal break and idiopathic ERMs. METHODS: This retrospective study included patients with an idiopathic ERM or an ERM associated with retinal break, who were followed up for ≥ 6 months after ERM removal. The postoperative functional and anatomical outcomes were compared between the groups. RESULTS: A total of 160 and 38 eyes (198 patients) were in the idiopathic and retinal break groups, respectively. There was no significant difference in the baseline anatomical and functional parameters between the groups. At 6 months after surgery and at the final follow-up, best-corrected visual acuity, central foveal thickness, and ectopic inner foveal layer improved significantly in both groups, but there was no significant difference between the groups. In latter 49.0% of patients, tests for metamorphopsia and aniseikonia were performed. There was a significant improvement in the scores of metamorphopsia (0.40 ± 0.38 to 0.27 ± 0.28; p < 0.001) and aniseikonia (6.07 ± 4.46 to 4.11 ± 3.52; p < 0.001) in the idiopathic group at 6 months after surgery, but not in the retinal break group. The idiopathic group had significantly greater circularity of ERM extent compared to the retinal break group (p = 0.025). CONCLUSION: Visual and anatomical improvements after removal of ERMs associated with retinal break and idiopathic ERMs were comparable. However, metamorphopsia and aniseikonia improved only after removal of idiopathic ERMs.
