自1968年Jensen与Lundbaek首先报道虹膜荧光素血管造影后,近十年来积累了不少报道。因此现在探讨关于这方面的研究、诊断及临床应用,并作出评价是适时的。虹膜毛细血管与视网膜及脑部血管相似,具有不沟通的内皮细胞层与基底膜,偶有外皮细胞。在灵长类动物内皮细胞之间有粘合物紧密接连(Vegge,1972)。由于这类细胞具有细胞间的紧密接连,荧光素不能通过血管壁而扩散。虹膜毛细血管可因组织缺氧、血管内外压力的改变、缺血、外伤与炎症而致损害。实验上荧光素血管造影可用作研究局部或全身应用活性药剂与其对
Since 1968, Jensen and Lundbaek first reported iris fluorescein angiography, the accumulation of a lot of reports over the past decade. Therefore, it is timely to explore the research, diagnosis and clinical application in this area and make the evaluation. Iris capillaries and the brain and blood vessels similar to the brain, with non-communicating layer of endothelial cells and the basement membrane, occasional skin cells. There is an adhesive bond between primate endothelial cells (Vegge, 1972). Due to the tight intercellular connections of these cells, fluorescein can not diffuse through the walls of blood vessels. Iris capillaries due to tissue hypoxia, changes in pressure inside and outside the blood vessels, ischemia, trauma and inflammation damage. Experimental fluorescein angiography can be used to study the local or systemic application of active agents and their counterparts
