目的 观察国人息肉状脉络膜血管病变 (polypoidal choroidal vasculopathy,PCV)的眼底和血管造影特征。 方法 对 9例 PCV患者进行眼底检查、荧光素眼底血管造影 (fundus fluorescein angiog-raphy,FFA)和吲哚青绿血管造影 (indocyanine green angiography,ICGA)检查。 结果 9例患者均为单眼患病。 7例患者具有脉络膜分支状血管网及血管末端息肉状膨大 ;2例患者血管网不明显 ,但息肉状膨大明显可见。7只眼伴有出血性视网膜色素上皮 (retinal pigmentepithelium,RPE)脱离 ,其中 4只眼可见血和血浆的分界线。眼底病变部位在黄斑部者 8例 ,视盘旁者 1例。 结论 国人 PCV患者大部分有脉络膜异常分支血管网 ,所有病例均有血管末端扩张呈息肉样灶 ;病变部位以黄斑部为主 ,大多合并有出血性 RPE脱离。
Objective To observe the fundus and angiographic features of polypoidal choroidal vasculopathy (PCV) in Chinese. Methods Nine patients with PCV underwent fundus examination, fundus fluorescein angiog-raphy (FFA) and indocyanine green angiography (ICGA). Results All the 9 patients were monocular. Seven patients had choroidal branch vascular network and terminal polypoid blood vessels; two patients with vascular network is not obvious, but obvious polypoid inflated. Seven eyes with hemorrhagic retinal pigment epithelium (retinal pigmentepithelium, RPE) detachment, including four eyes visible blood and plasma demarcation line. Fundus lesions in the macular in 8 cases, 1 case of optic disc. Conclusion Most of PCV patients in our country have choroidal abnormal branch vascular network. All cases have polypoid lesions at the distal end of the vessel. Macular degeneration is the main lesion in the lesion. Most of them have hemorrhagic RPE detachment.
