摘要
目的通过眼底荧光血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎａｎｇｉｏｇｒａｐｈｙ，ＦＦＡ）和吲哚青绿血管造影（ｉｎｄｏｃｙａｎｉｎｅｇｒｅｅｎａｎｇｉｏｇｒａｐｈｙ，ＩＣＧＡ）探讨中心性渗出性脉络膜视网膜病变（简称中渗）的脉络膜新生血管（ｃｈｏｒｏｉｄａｌｎｅｏｖａｓｃｕｌａｒｉｚａｔｉｏｎ，ＣＮＶ）特征。方法对２１例２２眼“中渗”患者同时进行ＦＦＡ与ＩＣＧＡ检查，并对两种不同的眼底血管造影图像进行对比分析。结果（１）２２只眼中１８眼ＦＦＡ与ＩＣＧＡ均发现ＣＮＶ，ＩＣＧＡ显示的ＣＮＶ较ＦＦＡ清晰，形态大小始终不变。（２）ＦＦＡ中４眼未发现ＣＮＶ，而ＩＣＧＡ造影其中２眼发现ＣＮＶ。（３）ＩＣＧＡ出现ＣＮＶ的部位４４％在光凝治疗范围，而ＦＦＡ仅２０％。结论ＩＣＧＡ出现的ＣＮＶ轮廓较ＦＦＡ清晰，定位准确。ＦＦＡ不能发现的ＣＮＶ，ＩＣＧＡ可以发现，给“中渗”患者提供了更可靠和更多的激光治疗机会。
Objective To study the characters of chorioidal neovascularization(CNV) in central exudative chorioretinopathy by comparing their fundus fluorescein angiography (FFA) and indocyanine green angiography(ICGA).Method Performing simultaneous FFA and ICGA on consecutive 21 patients (22 eyes),comparing and analyzing image characters.Results (1)Of the 22 eyes 18 were found to have CNV in both FFA and ICGA.The CNV is clearer in ICGA than in FFA.The size of the CNV is stable during the course of angiography.(2)There were 4 eyes showing no CNV in FFA,which,however,can be seen on ICGA.(3)44% of the CNV could be treated with laser according to the guide of ICGA,while only 20% by FFA.Conclusion ICGA can localize the CNV better and show the border of CNV clearer.ICGA is more sensitive in finding CNV comparing with FFA,which gives more chance for the treatment of photocoagulation by such patients.
