  • 简介:目的:比较经睫状体平坦部玻璃体切除术(parsplanavitrectomy,PPV)与PPV联合内膜剥离术(internallimitingmembranepeeling,ILMP)治疗高度近视黄斑裂孔临床效果。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(不剥离内膜);Ⅱ组21眼行玻璃体切除联合内膜剥离术,术中根据患者病情不同,给予不同辅助方式,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:玻璃体切除联合内膜剥离术可以显著提高高度近视黄斑裂孔闭合率和术后视力,但对于视网膜复位率较不剥膜者无明显区别。
