特发性息肉样脉络膜血管病变一例报告

A Case Report of Idiopathic Polypoidal Choroidal Vasculopathy

目的:报道1例特发性息肉样脉络膜血管病变的眼底荧光血管造影与吲哚青绿血管造影的临床特点。方法:常规眼科检查、眼底照相、荧光血管造影、吲哚青绿血管造影分析以及文献复习。结果:特发性息肉样脉络膜血管病变患者缺乏典型的玻璃疣,但可在视乳头与黄斑间出现大量泥沙样黄色渗出,眼底荧光血管造影中没有老年性黄斑变性样的新生血管,吲哚青绿血管造影中可见典型的息肉样脉络膜血管扩张,可单眼发病。结论:特发性息肉样脉络膜血管病变在临床表现以及眼底血管造影方面均有特征性改变。区分特发性息肉样脉络膜血管病变与老年性黄斑变性在疾病的视力预后、转归以及治疗处理上都有实际的临床意义。眼科学报2001;17:126～129。

Purpose: To report a case of idiopathic polypoidal choroidal vasculopathy (IPCV) and its angiographic characteristics.Methods: General ophthalmic check up, analyses of fundus picture, funds fluorescein angiography (FFA), indocyanine green angiography( ICGA) as well as literature review.Results: The lack of typical choroidal neovascularization (CNV) on FFA and characteristic polypoidal choroidal vasculopathy on ICGA as well as its unsymmetrical manifestation and discrepancy with age-related macular degeneratio (AMD) on the fundus picture are typical signs for the diagnosis of IPCV.Conclusion: The angiographic features on FFA and ICGA are specific for the diagnosis of IPCV. Differentiating IPCV and AMD has clinical significance in prognosing the visual acuity, progress and management of the diseases. Eye Science 2001; 17: 126 - 729.
