息肉状脉络膜血管病变的眼底血管造影表现

目的 观察息肉状脉络膜血管病变(PCV )的临床特征及眼底血管造影表现。 方法 回顾分析12例PCV患者12只眼的眼底检查、荧光素眼底血管造影(FFA)、吲哚青绿血管造影(ICGA)及其5例5只眼的光相干断层扫描(OCT)检查资料。 结果 12只眼均可见深层和(或)浅层出血，黄色脂质渗出。其中6只眼病变处见橘红色病灶，2只眼伴视网膜前出血。FFA检查，静脉期6只眼橘红色病灶内点状荧光，4只眼病变处可见脉络膜血管网。晚期均见息肉状强荧光点荧光素渗漏，2只视网膜前出血眼晚期未见荧光素渗漏。ICGA检查，12只眼晚期见强度不等、簇状或孤立的息肉状扩张灶，4只眼显示明显的脉络膜血管网。OCT检查，4只眼视网膜色素上皮（RPE）和脉络膜毛细血管高反射层呈穹窿状隆起，1只眼无改变。 结论 PCV眼底多见黄斑区出血性和(或)浆液性视网膜色素上皮脱离(RPED)和(或)神经上皮脱离，黄色脂质渗出。FFA及ICGA检查可见分支状脉络膜血管网及末梢膨大息肉状扩张灶。 （中华眼底病杂志，2004，20：310-312）

Manifestation of fundus angiograph of polypoidal choroidal vasculopathy

Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage, serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA.
