Abstract： 目的用多焦视网膜电图(multifocal electroretinography, mf-ERG)评价中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy, CSC)的患眼及对侧眼视网膜功能. 方法 mf-ERG检测经荧光素眼底血管造影确诊为单眼CSC患者20例40只眼,年龄31～53岁,平均年龄41岁,男13例,女7例.CSC患眼视力0.2～0.8,对侧眼视力0.8～1.5.同时设立对照组24例29只正常眼(视力≥1.0,无其它眼病),年龄30～54岁,平均年龄37岁.mf-ERG检测选用61个六边形刺激成分,提取所刺激部位的一阶反应波形,按不同离心度从中央向周边分成5个环反应波,对N1、P1波的振幅密度和潜伏期进行比较、分析. 结果不仅CSC患眼1～3环处P1,N1波的振幅密度较正常眼低,差异有非常显著性的意义(P＜0.01),而且CSC患眼的对侧眼1、2环P1,N1波的振幅密度较正常对照眼低,差异有显著性的意义(P＜0.05).同时CSC患眼的对侧眼1～2环处P1波振幅密度较患眼高,差异有非常显著性的意义(P＜0.01),但对侧眼各环N1波振幅密度较CSC患眼差异无显著性的意义(P＞0.05).而且5个环N1、P1波潜伏期3组比较差异无显著性的意义(P＞0.05). 结论 CSC是一种累及双眼的黄斑病变,不仅表现为患眼黄斑区视网膜功能下降,而且对侧眼黄斑区视网膜功能也有影响.mf-ERG是一种敏感的视功能检查方法.
