摘　　要：目的研究特发性黄斑前膜患者的斜坡角与视力的相关性。方法回顾性分析我院52例(62眼)白内障合并特发性黄斑前膜患者的临床资料。手术均由同一术者完成,采用标准的白内障超声乳化+人工晶体植入术。术后使用国际标准视力表检查最佳矫正视力(BCVA),再转换为最小分辨角的对数视力(LogMAR)进行分析。应用光学相干断层扫描仪(OCT)测量患者黄斑中心凹厚度(CFT)、鼻侧斜坡角(NSA)及颞侧斜坡角(TSA)。结果CFT与LogMAR具有显著正相关(r=0.478,P=0.001)。当NSA≥22°,NSA与LogMAR具有显著正相关(r=0.633,P=0.005);当NSA<22°时,NSA与LogMAR具有显著负相关(r=-0.629,P=0.000)。当TSA≥22°,TSA与LogMAR具有显著正相关(r=0.611,P=0.012);当TSA<22°时,TSA与LogMAR具有显著负相关(r=-0.582,P=0.000)。结论斜坡角与BCVA具有显著的相关性。通过分析观察黄斑前膜患者斜坡角,有助于客观预测患者视功能水平。Objective To investigate the correlation between macular slope angle(SA)and visual acuity in patients with idiopathic epiretinal membrane(IERM).Methods A total of 62eyes of 52patients who were diagnosed as IERM and underwent phacoemulsification with intraocular lens implantation were analyzed.The best corrected visual acuity(BCVA)after cataract surgery was examined using the international standard visual acuity chart,and then converted to LogMAR visual acuity for analysis.Optical coherence tomography(OCT)was used to measure the cental foveal thickness(CFT),nasal slope angle(NSA)and temporal slope angle(TSA).Results Correlation analysis showed that there was a significant positive correlation between CFT and LogMAR(r=0.478,P=0.001).Significant positive correlation between NSA and LogMAR(r=0.633,P=0.005)were observed when NSA≥22°,and there was a significant negative correlation between NSA and LogMAR(r=-0.629,P=0.000)when NSA<22°.TSA was positively correlated with LogMAR(r=0.611,P=0.012)when TSA≥22°,and there was a significant negative correlation between TSA and LogMAR(r=-0.582,P=0.000)when TSA<22°.Conclusion The macular SA was significantly correlated with BCVA.It may be a novel indicators to predict the level of visual function by analyzing the macular SA in patients with IERM.
