RESUMO
Objective:To observe the treatment effect of 25-gauge pars plana vitretomy with the inverted internal limiting membrane (ILM) flap and autologous serum coverage in high myopia macular hole (HMMH) eyes.Methods:17 patients (17 eyes) with HMMH were selected from the Affiliated Hospital of Chinese Medicine Hospital of Xinjiang Medical University from June 2019 to March 2020. The minimum diameter of macular hole in all patients was ≤500 μm. They were diveded into group A (10 eyes) and group B (7 eyes) according to the random number table method. The group A underwent 25-gauge pars plana vitretomy + inverted ILM falp technique + autologous serum coverage; The group B (5 eyes) underwent 25-gauge pars plana vitretomy with ILM peeling technique. The best corrected visual acuity (BCVA) before and after surgey and the macualr hole closure rates were observed.Results:There was no significant difference in BCVA between the two groups before operation and at 6 months after operation ( P>0.05); The postoperative macular hole closure rate was 8/10 in group A and 4/7 in group B. There was no significant difference in macular hole closure rate between the two groups ( P>0.05); The BCVA of the two groups at the last follow-up after operation was significantly higher than that before operation ( P<0.05). Conclusions:Vitrectomy combined with inverted ILM falp technique is a safe and effective method in the treatment of high myopia macular hole with diameter ≤500 μm.
