Abstract. Purpose:Pseudo-macular hole(PMH)may deteriorate visual acuity because of a partial foveal thickness decrease. Full-thickness macular hole is one of the complications after performing pars plana vitrectomy with removing epimacular membrane and internal limiting membrane(ILM)for PMH. Once this postoperative full-thickness macular hole occurs, additional treatment becomes difficult because ILM has already been peeled. Pars plana vitrectomy with Hemi-inverted ILM flap technique for PMH was investigated its usability. Subjects and Methods:Eleven eyes of 11 patients(mean age 71.1±6.7 years old)underwent PPV with inverted ILM flap technique for MH between February 2011 and March 2014. Surgical criteria were PMHs with foveal thickness of 100μm or less. Results:Mean preoperative logMAR visual acuity(VA)was 0.44±0.32 and mean postoperative VA was 0.19±0.19, respectively(Wilcoxon signed-rank test, p=0.0033). Mean preoperative foveal thickness of PMH increased from 77.6±20.8μm to 191.5±79.3μm postoperatively(paired t-test, p=0.00065). Conclusion:Pars plana vitrectomy with Hemi-inverted ILM flap technique for PMH may be useful without postoperative complication, such as full-thickness macular hole. Long-term follow-up and increase in number of cases is needed.
