Abstract

Purpose: This study aimed to observe intraoperative changes in macular hole (MH) form using intraoperative optical coherence tomography (iOCT).

Methods: A total of 10 eyes from 10 patients with MH who underwent vitrectomy using iOCT from May 2015 to October 2015 at the Yamagata University Hospital were retrospectively evaluated. Accordingly, 25-gauge pars plana vitrectomy using iOCT with internal limiting membrane (ILM) peeling and sulfur hexafluoride gas tamponade was performed on each patient. During surgery, MHs were observed using iOCT over four points, namely, before posterior vitreous detachment (PVD) formation, after PVD formation, after ILM peeling, and after fluid-gas exchange. Thereafter, basal MH diameter and minimum aperture MH diameter were postoperatively analyzed.

Results: Before PVD formation, after PVD formation, after ILM peeling, and after fluid-gas exchange, the mean basal MH diameters were 690.7 ± 268.4, 683.3 ± 274.2, 683.7 ± 269.5, and 668.3 ± 261.4 μm, while the mean minimum aperture MH diameters were 278.3 ± 165.2, 283.0 ± 170.2, 257.0 ± 127.8, and 188.0 ± 105.0 μm, respectively. The mean minimum aperture MH diameter decreased significantly after fluid-gas exchange (one-way repeated measures ANOVA, p < 0.05). None of the patients exhibited intraoperative closure of the MHs. However, MH closure was confirmed in all patients after the surgery.

Conclusion: None of the patients demonstrated intraoperative MHs closure. Accordingly, the minimum aperture MH diameter was the first change formation to close after fluid-gas exchange.

术中光学相干断层扫描观察黄斑孔洞。

目的:利用术中光学相干断层扫描(iOCT)观察术中黄斑孔(MH)形态的变化。方法:对2015年5月至2015年10月在山形大学医院行玻璃体切除术的10例MH患者的10只眼进行回顾性评价。因此，对每位患者进行了25号玻璃体切除术，采用iOCT结合内限制膜(ILM)剥离和六氟化硫气体填塞。术中采用iOCT在玻璃体后脱离(PVD)形成前、PVD形成后、ILM剥离后和液气交换后4个点观察MHs。术后分析基础MH直径和最小孔径MH直径。结果:PVD形成前、PVD形成后、ILM剥离后和气液交换后，平均基础MH直径为690.7±268.4、683.3±274.2、683.7±269.5和668.3±261.4 μm，平均最小孔径MH直径分别为278.3±165.2、283.0±170.2、257.0±127.8和188.0±105.0 μm。气液交换后平均最小孔径MH直径显著降低(单因素重复测量方差分析，p < 0.05)。术中没有一例患者出现mhh闭合。然而，手术后所有患者均证实MH闭合。结论:无一例患者术中MHs闭合。因此，最小孔径MH直径是气液交换后最先改变地层闭合的。
