急性中心性浆液性脉络膜视网膜病变的吲哚青绿造影特征

目的通过分析急性中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy,CSC)患者的脉络膜血管造影特点,探究其发病机理。方法应用海德堡造影系统HRA2对41例41只眼急性CSC进行FFA和ICGA检查,并对结果进行分析。结果 38例急性CSC患者在ICGA早期于FFA渗漏点处见局限性脉络膜充盈缺损,其周围脉络膜静脉扩张,中晚期可见渗漏。3例CSC患者FFA检查未见渗漏点,但ICGA仍可见活动性渗漏。结论 ICGA对于研究急性CSC患者脉络膜的异常循环具有重要价值。

Characteristics of indocyanine green angiography in acute central serous chorioretinopathy

OBJECTIVE To analyse the characters of indocyanine green angiography（ICGA） and fundus fluorescein angiography（FFA） in acute central serous chorioretinopathy（CSC） and investigate the pathogenetic mechanisms.METHODS Forty-one eyes of 41 cases of CSC were examined with Heidelberg Retina Angiography 2（HRA2）.Simultaneous images of ICGA and FFA were analysed.RESULTS Thirty-eight eyes with acute CSC showed choroidal filling defect and regional dilated choroidal veins in early phase of ICGA and leakage in middle and late phase of ICGA.The choroidal filling defect corresponded with the RPE leakage in FFA.In 3 eyes with CSC,there was no leakage in FFA,while active leakage could be seen in ICGA.CONCLUSIONS In patients with the acute CSC,ICGA is a useful tool to detect the abnormal circulation of choroid.
