Abstract To investigate the surgical outcomes of pars plana vitrectomy (PPV) combined with inverted multi-layer internal limiting membrane (ILM) flap for the treatment of macular hole retinal detachment in high myopia.We retrospectively analysed the medical records of macular hole retinal detachment (MHRD) patients with high myopia.The patients were divided into two groups with different surgical procedure: inverted multi-layer Kit Drive ILM flap group (group 1, 27 eyes) and the ILM peeling group (group 2, 29 eyes).Retinal reattachment rate, macular hole closure rate at last follow-up and BCVA at 6 months post-operation were compared between the two groups.After primary PPV and silicone oil removal, the retinal reattachment rate was 96.
3% in group 1 and 93.1% Kitchen Linen in group 2 respectively at last follow-up, showing no statistically significant difference (odds ratio = 0.525, P = 1.000).All eyes in group 1 had type I macular closure (100%, 27/27), while only 7 eyes (24.
1%, 7/29) in group 2 have type I macular hole closure.The difference was statistically significant (odds ratio = 0, P 0.05).PPV combined with inverted multi-layer ILM flap could achieve better anatomical outcomes than ILM peeling technique with no significant advantage in functional outcomes.
