Purpose: To assess the closure rate of large full-thickness macular holes (FTMH) associated with epiretinal membrane (ERM) with a combined epiretinal and internal limiting membrane retracting door flap. Methods: Retrospective chart review of patients treated at a single tertiary retina practice between January 2017 and November 2019. Individuals with FTMH larger than 400 μm and co-diagnosis of ERM who underwent surgical repair with an ERM flap were included. Patients underwent pars plana vitrectomy with peeling of ERM that was positioned as a retracting door flap to cover the FTMH. Primary outcome was closure rate at 6 months following surgery. Final surgical success rate and visual acuity were secondary outcomes. Results: Among 7 eyes of 7 patients, 6 eyes achieved primary surgical success and final surgical success rate was achieved in all 7 eyes with a large FTMH repaired with ERM flap. The mean minimum linear diameter of the FTMH was 681 μm ± 295. All patients had follow-up greater than 6 months, with a mean duration of 17 months (range 14–23 months). Visual acuity improved from a mean of 0.9 ± 0.3 logMar (20/160) before surgery to 0.3 ± 0.5 logMar (Snellen 20/40), postoperatively. Conclusion: Large FTMH with concurrent ERM that are managed with an ERM flap have high single-surgery success rate. [ABSTRACT FROM AUTHOR]
