Purpose:
This study aims to describe the structural changes and surgical outcomes of full-thickness macular holes (FTMHs) induced by vitreomacular traction with broad vitreomacular attachment (VMA).
Methods:
A retrospective analysis of idiopathic FTMHs from October 2010 to May 2022 was conducted. Patients with FTMHs and no retinal detachment (RD) induced by broad VMA (the study group) were compared with a control group consisting of typical FTMHs with focal VMA.
Results:
Thirty-one eyes had broad VMA-associated FTMH, among which seven eyes (22%) were with concurrent RD. Among the total of 24 cases without RD, 8 (33%) exhibited schisis. The incidence of lamellar holes associated epithelial proliferation and multiple membrane traction was significantly higher in the study group. One hundred percent FTMH closure was observed postoperatively in both groups. Although the postoperative visual acuity was not significantly different, the study group showed a greater ellipsoid zone disruption length.
Conclusion:
Broad VMA-induced FTMHs are characterized by diverse macular structural changes, including schisis and macular detachment. These FTMHs are associated with a higher incidence of lamellar holes associated epithelial proliferation and multiple membrane traction. Surgical outcomes for FTMHs induced by broad VMA are similar to those induced by typical focal VMA, with both groups demonstrating a 100% hole-closure rate.
