目的：探究玻璃体切除(PPV)联合内界膜翻转填塞术治疗高度近视黄斑裂孔性视网膜脱离(MHRD)的临床疗效。

方法：回顾性临床研究。选取2017-10/2021-10本院收治的高度近视MHRD患者63例64眼为研究对象，根据手术方式的不同分为A组(34例35眼，接受PPV联合内界膜翻转填塞术治疗)和B组(29例29眼，接受PPV联合内界膜剥除术治疗)。术后随访6mo，比较两组患者的裂孔闭合率、视网膜脱离复位率； 术前，术后1wk，1、3、6mo时最佳矫正视力(BCVA)； 记录术后并发症发生情况。

结果：术后6mo内，A组的裂孔闭合率明显高于B组(P<0.05)； 两组患者的视网膜脱离复位率比较无差异(P>0.05)。术后随着时间的延长，两组患者的BCVA较术前明显改善(P<0.05)； 术前，术后1wk，1、3、6mo时，两组患者的BCVA比较无明显差异(P>0.05)。术后两组患者均出现一定并发症，但两组患者的并发症发生率比较无差异(P<0.05)。

结论：PPV联合内界膜翻转填塞术治疗高度近视MHRD具有良好的临床疗效，能有效改善患者的BCVA，提高裂孔闭合率，且不会影响患者眼压，安全有效。

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.
