Long-term Outcomes of Macular Hole Retinal Detachment in Highly Myopic Eyes after Surgical Reattachment

PURPOSE: To evaluate visual acuity changes over 3 years following surgical reattachment of macular hole retinal detachment (MHRD) developed in high myopia. METHODS: A retrospective analysis was performed using the medical records of patients with highly myopic eyes who underwent pars plana vitrectomy with internal limiting membrane peeling or the internal limiting membrane flap technique for MHRD. Changes in best-corrected visual acuity (BCVA) were measured at baseline, 6 months, 1 year, 2 years, and 3 years. RESULTS: Of the 22 eyes analyzed, macular hole was closed in 13 and unclosed in nine. BCVA significantly improved from 1.61 ± 0.39 logarithm of the minimum angle of resolution (logMAR) at baseline to 1.17 ± 0.43 logMAR at 6 months and 1.33 ± 0.48 logMAR at 2 years after MHRD surgery. At 3 years, BCVA significantly decreased compared with that at 6 months, and visual improvement from baseline was not significant. BCVA and proportion of vision loss ≥0.3 logMAR were not different between the closed and unclosed macular hole groups. CONCLUSIONS: Visual improvement after surgical reattachment of MHRD in high myopia was not maintained, and favorable macular hole closure effects were not observed at 3-year follow-up.
