特发性息肉状脉络膜血管病变 (idiopathic polypoidal choroidal vasculopathy,IPCV)是近年认识的一种与渗出型老年黄斑变性 (age- related macular degeneration,AMD)表现较为相似的眼病 ,但两种疾病在流行病学、病情转归、视力预后及治疗等方面均有较大的不同。因此 IPCV诊断及鉴别诊断具有较为重要的临床意义。 IPCV的吲哚青绿血管造影 (indocyanine green angiography,ICGA)显示有分支状脉络膜血管网及末梢的息肉状血管扩张等特征性表现 ,为 IPCV诊断与鉴别诊断提供了重要的依据。 Idiopathic polypoidal choroidal vasculopathy (IPCV) is a kind of eye disease that has been recognized in recent years, which is similar to the exudative age-related macular degeneration (AMD). However, both diseases are prevalent Pathology, prognosis and treatment of prognosis and treatment are quite different. Therefore, IPCV diagnosis and differential diagnosis have more important clinical significance. Indocyanine green angiography (ICGA) of IPCV shows characteristic features such as dilated vessels of the branch-like choroidal network and terminal polypoid vasculature, which provide an important basis for the diagnosis and differential diagnosis of IPCV.
