正常人吲哚青绿血管造影眼底后部强荧光区的表现及临床意义         【摘要】目的观察正常人吲哚青绿血管造影(indocyaninegreenangiography,ICGA)眼底后部强荧光区形态表现,探讨后部脉络膜的循环状态。方法对50例正常人行常规ICGA检查。结果①眼底后部强荧光区出现时间平均为(±)秒;②后部强荧光区的形态为上下两团对称型者占58%,为一团型者占42%;③后部强荧光区的面积平均为(±)mm2;④后部强荧光区持续时间平均为(±)秒。结论正常人ICGA检查在眼底后部可见有明确的强荧光区,其时限及形态特征体现后部脉络膜的正常血液供应及循环状态,此参数可为临床诊断提供参考依据。【关键词】吲哚青绿/诊断应用荧光素血管造影术脉络膜疾病/诊断中国书资料分类法分类号 GUOXirang,ZHAOZhaoxia,,Zhengzhou450003,China 【Abstract】 Purpose Toobservethefeaturesofthehyperfluorescent areasintheposteriorocularfundusdetectedbyindocyaninegreenangiography(ICGA)inhealthyvolunteers,andtostudycirculatorypropertiesofchoroid.
