Abstract:
AIM: To investigate the clinical efficacy of pars plana vitrectomy(PPV)combined with inverted internal limiting membrane flap technique in the treatment of macular hole retinal detachment(MHRD)in high myopia.METHODS: A retrospective clinical study was conducted. A total of 63 patients(64 eyes)with high myopia and MHRD who treated at our hospital from October 2017 to October 2021 were selected as research subjects. They were divided into two groups according to different surgery, with 34 cases(35 eyes)who received PPV combined with inverted internal limiting membrane flap technique in group A, and 29 cases(29 eyes)received PPV combined with internal limiting membrane peeling in group B. The patients were followed up for 6mo. The two groups were compared in terms of the hole closure rate, the reduction rate of retinal detachment and best corrected visual acuity(BCVA)before operation and at 1wk, 1, 3 and 6mo after operation, and the postoperative complications were recorded.RESULTS: The hole closure rate within 6mo after operation was significantly higher in group A than in group B(P<0.05), but there was no statistically significant difference in the reduction rate of retinal detachment(P>0.05). The BCVA of the two groups was significantly improved over time after operation(P<0.05). There was no statistically significant difference in BCVA between the two groups before operation and at 1wk, 1, 3 and 6mo after operation(P>0.05). Complications were observed in the two groups, but there was no statistically significant difference in the incidence of complications between the two groups(P<0.05).CONCLUSION: PPV combined with inverted internal limiting membrane flap technique is safe and effective in the treatment of MHRD in high myopia, which can effectively improve the patients' BCVA and the hole closure rate without influence on intraocular pressure.
