眼底镜的发明和眼底荧光血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎａｎｇｉｏｇｒａｐｈｙ，ＦＦＡ）的引入，使得对眼底结构和功能的认识及很多眼底病的诊治向前迈了一大步。但由于脉络膜血管被色素上皮及自身色素遮挡，观察困难，对血管构筑和血流动力学及在眼病中的地位和作用了解不多。以前对脉络膜循环的了解多基于离体铺片或血管铸型研究或ＦＦＡ，这些研究在一定程度上揭示了脉络膜血管的构筑，但临床上却需要一种能直接观察循环的动态方法以解决临床实际问题。７０年代以来以Ｆｌｏｗｅｒ为代表的研究者们引入吲跺青绿脉络膜血管造影（ｉｎｄｏｃｙａｎｉｎｅｇｒｅｅｎｃｈｏｒｏｉｄａｌａｎｇｉｏｇｒａ－ｐｈｙ，ＩＣＧＣＡ）［１］，使人们能更清楚而直观地了解脉络膜血循环动态情况，随着技术的不断进步和经验的积累，ＩＣＧＣＡ将逐步被人们所认识，ＩＣＧＣＡ在一些发达国家已较多应用于临床。兹将ＩＣＧＣＡ的基本情况、临床应用及技术新进展分三篇介绍。
The invention of ophthalmoscope and the introduction of fundus fluorescein angiography (FFA) have taken a big step forward in understanding the structure and function of fundus and many fundus diseases. However, due to the choroidal blood vessels blocked by the pigment epithelium and its own pigments, difficult to observe, on the blood vessels and hemodynamics and in the status and role of the eye did not know much. Previously, the understanding of the choroidal circulation based on extracorporeal membrane or vascular cast research or FFA, these studies to a certain extent revealed the construction of choroidal blood vessels, but clinically need a direct observation of the circulation dynamic method to solve the clinical Practical problems. Since 1970’s, researchers represented by Flower introduced indocyanine green color modal angiogra-phy (ICGCA) [1] so that people can understand the dynamic state of choroidal blood circulation more clearly and intuitively. With the continuous improvement of technology and The accumulation of experience, ICGCA will be gradually recognized by people, ICGCA in some developed countries have been more used in clinical. ICGCA will be the basic information, clinical applications and new progress in technology introduced in three.
