Clinical efficacy of vitrectomy combined with inverted internal limiting membrane flap technique for macular hole retinal detachment of high myopia

AIM: To evaluate the effectiveness of pars plana vitrectomy(PPV)combined with inverted internal limiting membrane(ILM)flap technique for macular hole retinal detachment(MHRD)of high myopia. METHODS: This was a retrospective case series. Totally 27 patients(27 eyes)who were diagnosised with MHRD of high myopia and underwent vitrectomy combined with inverted ILM flap covering technique were eIlrolled in this study. The diopter was ≥-6.00D and axial length was ≥26mm. The mean age was 53.69±7.23 years. And there 9 males and 18 females. The logarithm of the minimum angle of resolution(LogMAR)best-corrected visual acuity(BCVA)was 1.41±0.28. All patients were performed PPV with inverted ILM flap, resected the vitreous gel and cortex completely. Bright blue G stained the ILM around the fovea. The ILM was peeled off around the MH, and some portion of the ILM flap was left attached to the edge of the MH. Covering the MH with the ILM flap.Then, C3F8 gas or silicone oil was injected into the vitreous cavity. The mean follow-up was more than 6mo and BCVA, MH closure, retinal reattachment, complications were retrospectively observed. RESULTS: After surgery, visual acuity improved in 21 eyes(78%), unchanged in 4 eyes(15%), decreased in 2 eyes(7%). The mean LogMAR BCVA was 0.84±0.40, the difference was significant(t=7.32, PCONCLUSION: PPV combined with inverted internal limiting membrane flap is an effective and safe management for the MHRD of high myopia
