Abstract

This study was conducted to assess the anatomical and functional outcome of using inverted internal limiting membrane (ILM) flap technique with vitrectomy to treat retinal detachment caused by macular hole (MHDR) in highly myopic eyes. In this prospective observational study, data from 26 patients with MHDR that underwent vitrectomy with the inverted ILM flap technique combined with C3F8 tamponade or silicon oil were analyzed. Results showed that of the 26 patients, 16 were female and 10 were male. The mean age was 61.37 ± 8.59. The mean axial length was 28.00 ± 2.48 mm. The majority of the patients (74.04%) had posterior staphyloma. The success rate of the initial surgery was 88.46%. At 6 - month follow up, all patients had retinal detachment. The macular hole closure rate was 62.96%. The BCVA at 6 months postoperation was 1.33 ± 0,24 logMAR. The inverted ILM flap technique with the presence of bridging tissue over the macular hole is effective in closing the macular hole and can improve the postoperative best - corrected visual acuity in eyes with MH retinal detachment by bridging tissue over the MH.
