简介：目的：比较经睫状体平坦部玻璃体切除术（parsplanavitrectomy,PPV）与PPV联合内界膜剥离术（internallimitingmembranepeeling,ILMP）治疗高度近视黄斑裂孔的临床效果。方法：回顾性分析高度近视黄斑裂孔患者（伴或不伴黄斑裂孔性视网膜脱离）33例36眼的病例资料。根据手术方式不同,分为Ⅰ组和Ⅱ组。Ⅰ组15眼行玻璃体切除术（不剥离内界膜）;Ⅱ组21眼行玻璃体切除联合内界膜剥离术,术中根据患者病情不同,给予不同的辅助方式,如行硅油填充、C3F8填充、光凝、冷凝等。术后随访3-12mo,以术后最佳矫正视力（bestcorrectedvisualacuity,BCVA）、裂孔闭合及视网膜复位情况作为疗效观察指标,并将两组数据进行统计学分析。结果：Ⅰ组15眼术后最佳矫正视力（LogMAR）较术前平均提高0.167,差异有统计学意义（t=2.46,P=0.027）;Ⅱ组术后最佳矫正视力（LogMAR）较术前平均提高0.456,差异有统计学意义（t=6.753,P=0.000）;两组间术后视力提高程度比较,差异有统计学意义（t=-2.943,P=0.006）。Ⅰ组患者黄斑裂孔闭合率46.67%;Ⅱ组患者黄斑裂孔闭合率85.71%;比较两组术后裂孔闭合率,差异有统计学意义（χ^2=6.287,P=0.025）。Ⅰ组视网膜最终复位率91.67%。Ⅱ组视网膜最终复位率94.73%,比较两组患者视网膜复位情况,差异无统计学意义（χ^2=0.856,P=0.418）。结论：玻璃体切除联合内界膜剥离术可以显著提高高度近视黄斑裂孔的闭合率和术后视力,但对于视网膜的复位率较不剥膜者无明显区别。

简介：目的:观察玻璃体切除联合带蒂的非翻瓣内界膜(ILM)转位手术治疗大直径黄斑裂孔(macularhole,MH)的效果。方法:前瞻性研究。2016-12/2017-02于江苏省人民医院收治的9例10眼经频域光学相干断层扫描(SD-OCT)确诊为大直径MH患者(MH>400m),进行玻璃体切除联合ILM转位术。术前、术后1d,1wk,1、3、6mo随访SD-OCT、最佳矫正视力(bestcorrectedvisualacuity,BCVA)及微视野检查。结果:患者裂孔闭合率为100%;术前BCVA(LogMAR)1.19~0.54,术后视力提高显著,末次随访0.70~0.50(P=0.005);黄斑8°平均视网膜光敏感度(MS)值术前3.14~4.52dB、术后末次随访8.91~5.53dB(P=0.008);黄斑2°MS值术前1.46~2.94dB、术后末次随访6.33~4.90dB(P=0.008)。术前固视不稳定8眼,术后末次随访固视不稳定1眼。结论:玻璃体切除联合内界膜转位手术可以有效治疗大直径MH,具有较高的裂孔闭合率,术后视功能改善显著。

简介：目的：比较无菌空气填充和C_3F_8填充在玻璃体切割（PPV）联合内界膜瓣（ILMF）覆盖术中治疗特发性黄斑裂孔（IMH）的疗效差异。方法：回顾性对照研究。选取武汉大学人民医院眼科2014-01/2017-06就诊的符合纳入标准的IMH患者,行PPV联合黄斑区ILMF翻转覆盖黄斑裂孔术,根据术中是否行C_3F_8填充,分为球内空气填充组（A组112眼）和球内C_3F_8填充组（B组63眼）,比较两组术后高眼压发生情况、黄斑裂孔闭合率、术后1、3mo时最佳矫正视力（BCVA）和黄斑区结构重建情况。结果：A组和B组在术后1、3mo时,较术前BCVA均有提高,差异有统计学意义（P〈0.05）;两组手术后1mo时BCVA比较差异均无统计学意义,术后3mo时,A组BCVA较B组恢复更佳,差异具有统计学意义（P〈0.05）;A组黄斑裂孔闭合率为97.5%,B组为96.8%,两组比较差异无统计学意义;两组的光感受器细胞内外节交界面连接带（EZ）缺损直径较术前均有明显减小,差异有统计学意义（P〈0.05）,在术后1、3mo时两组比较,差异均无统计学意义;B组术后高眼压发生率为9.5%,而A组无术后高眼压情况发生,两者差异有统计学意义（P〈0.05）。结论：PPV联合ILMF覆盖治疗特发性黄斑裂孔安全有效,玻璃体腔无菌空气填充可减少术后高眼压发生率,在该手术中可以代替C_3F_8填充。
