Purpose: To describe the visual recovery and prognostic factors after macular hole surgery.
Methods; A retrospective chart review was conducted. Charts of patients with idiopathic macular holes who underwent surgery by a single surgeon at Severance Hospital between January 1, 2013 and July 31, 2015 were reviewed. The best-corrected visual acuity (BCVA) score was recorded preoperatively and at 1 day and 1, 3, 6, 9, and 12 months after surgery. The variables of age, sex, macular hole size, basal hole diameter, choroidal thickness, and axial length were also noted.
Results; Twenty-six eyes of 26 patients were evaluated. Twenty-five patients (96.2%) showed successful macular hole closure after the primary operation. The BCVA stabilized 6 months postoperatively. A large basal hole diameter (p = 0.006) and thin choroid (p = 0.005) were related to poor visual outcomes. Poor preoperative BCVA (p < 0.001) and a thick choroid (p = 0.020) were associated with greater improvement in BCVA after surgery.
Conclusions: Visual acuity stabilized by 6 months after macular hole surgery. Choroidal thickness was a protective factor for final BCVA and visual improvement after the operation.
