摘要 目的观察中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)的视觉电生理表现并做定量分析。方法 8例男性患者经过眼底荧光造影和光学相干成像确诊为单眼CSC后行全视野模式翻转视觉诱发电位(PVEP)、全视野闪光视网膜电图(FERG)、视杆细胞多焦视网膜电图(Rod-mfERG)和视锥细胞多焦视网膜电图(Cone-mfERG)检查。患眼为研究组,健眼为对照组。结果患眼和健眼的PVEP和Cone-mfERG表现出明显差异(P<0.05),FERG和Rod-mfERG未出现明显差异。对于空间频率为1°和0.25°的PVEP,患眼较健眼的P100波的幅值分别降低42.43%和37.60%,峰时延迟13.84ms和8.50ms,而在Cone-mfERG检查中患眼较健眼P1波幅值密度在1、2环分别降低40.93%和26.02%。结论视觉电生理检查尤其是PVEP和Cone-mfERG可以对CSC进行诊断及定量分析。
