目的：评价黄斑裂孔手术后视网膜血管密度和视网膜敏感度（RS）的上级倒置内界膜瓣技术。21例特发性黄斑裂孔患者采用上级内界膜翻转技术和曲安奈德进行27 G玻璃体切割术。测量包括RS，这是测量与微视野，以及视网膜血管密度在浅毛细血管丛（SCP）和深毛细血管丛（DCP），这是测量与光学相干断层扫描血管造影术。结果：术后6个月，黄斑下区视网膜厚度无明显变化，黄斑上区视网膜厚度明显降低（P < 0.01）。两个扇区的SCP血管密度在所有术后时间点均无变化。术后3个月时，两个分区DCP血管密度均显著增加（P < 0.01），6个月时恢复至基线水平。术后3个月和6个月下节段RS分别增加47%和61（分别为P < 0.05和P < 0.001），但上级部门的RS仅在术后6个月增加，仅增加22%结论：内界膜剥离术后上级区RS恢复较低，可能影响术后视功能。
Purpose: To evaluate retinal vessel density and retinal sensitivity (RS) after macular hole surgery with the superior inverted internal limiting membrane flap technique.Methods: Retrospective, observational case series. Twenty-one patients with idiopathic macular hole underwent 27-gauge vitrectomy with the superior inverted internal limiting membrane flap technique and triamcinolone acetonide. Measurements included RS, which was measured with microperimetry, as well as retinal vessel density in the superficial capillary plexus (SCP) and deep capillary plexus (DCP), which was measured with optical coherence tomography angiography. All parameters were evaluated in the superior and inferior sectors of the macula preoperatively and 1, 3, and 6 months postoperatively.Results: Six months postoperatively, retinal thickness in the inferior sector was unchanged, but retinal thickness in the superior sector decreased significantly (P < 0.01). SCP vessel density in both sectors was unchanged at all postoperative time points. DCP vessel density in both sectors increased very significantly at 3 months (P < 0.01) and returned to baseline at 6 months. RS in the inferior sector increased by 47% 3 months postoperatively and by 61% 6 months postoperatively (P < 0.05 and P < 0.001, respectively), but RS in the superior sector increased only at 6 months postoperatively and only by 22% (P < 0.05).Conclusion: Lower recovery of RS in the superior sector suggests that internal limiting membrane peeling might affect the postoperative visual function.
