摘要
目的探讨中心性浆液性脉络膜视网膜病变（ｃｅｎｔｒａｌｓｅｒｏｕｓｃｈｏｒｏｉｄｏｒｅｔｉｎｏｐａｔｈｙ，ＣＳＣ）的发病机理。方法用激光扫描检眼镜（ｓｃａｎｎｉｎｇｌａｓｅｒｏｐｈｔｈａｌｍｏｓｃｏｐｅ，ＳＬＯ）对２０例ＣＳＣ患者进行无赤光（蓝色光）眼底检查、眼底荧光素血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎａｎｇｉｏｇｒａｐｈｙ，ＦＦＡ）及靛青绿血管造影观察。结果（１）蓝色光眼底检查可清晰见到ＣＳＣ的神经视网膜脱离及色素上皮脱离的隆起。（２）ＦＦＡ能清晰显示渗漏点，还可见脉络膜背景荧光增强及晚期视乳头的强荧光。（３）ＩＣＧＡ早期可见脉络膜的充盈迟缓、高灌注和小叶扩张，中晚期可见较ＦＦＡ更多的强荧光点，患眼１００％有弥漫性的脉络膜渗漏，患者的“健眼”或以前ＣＳＣ已临床治愈的眼均可见脉络膜强荧光点，此外尚可见涡静脉异常等。结论ＣＳＣ患者有明显的脉络膜循环紊乱。用ＳＬＯ对ＣＳＣ患者进行无赤光、ＦＦＡ和ＩＣＧＡ眼底血管检查。
Objectives To know the results of indocyanine green angiography (ICGA) in central serous chorioretinopathy (CSC) and approach its pathogenetic mechanisms. Methods 20 cases of CSC were examined by scanning laser ophthalmoscope to perform blue laser beam examination, fundus fluorescein angiography (FFA) and indocyanine green angiography. Results (1)The blue laser beam: The elevation lesions of the sensory retinal and retinal pigment epithelial detachment were clearly found. (2)ICGA: In the early phase, choroidal delayed filling (95.0%), choroidal hyper perfusion (80.0%), choriocapillary dilatation, and in the late phase, hyperfluorescent spots (95.0%), diffuse choroidal hyperfluorescence (77.5%), abnormal fluorescence over vortex vein were found. (3) FFA demonstrated the hyperfluorescence of the choroidal background and the optic disc. Conclusions CSC patients have obvious choroidal circulatory disorder and the ICGA is a good method for the study of the pathogenetic mechanisms of the CSC and its therapeutic evaluation.
