ICGA can show the CNV which FFA can not. ICGA is more sensitive and accurate than FFA to show the numerous, location and range of CNV. So ICGA is an important method to diagnose exudative AMD and to direct laser coagulating.

• ICGA能发现 FFA不能发现的 CNV,在显示 CNV的数量、位置、范围等方面比 FFA敏感和准确 ,是诊断渗出型 AMD的 CNV和指导其激光光凝的?
