急性视网膜坏死综合征的荧光素眼底血管造影分析

Analysis of the fluorescein angiogram of acute retinal necrosis syndrome

目的 :了解急性视网膜坏死综合征荧光素眼底血管造影图像的特征。方法 :用荧光素眼底血管造影方法检查 16例 (2 1只眼 )急性视网膜坏死综合征患者 ,分析其图像特征。结果 :造影结果显示 ,视乳头均呈高荧光 ,视网膜主分枝动脉变细、有白鞘 ,但均显荧光 ,充盈可迟缓 ,仅 1例主分枝动脉部分闭塞 ,静脉迂曲、着染、渗漏。视网膜坏死灶多见于周边部 ,造影早期显不均匀弱荧光 ,晚期显强荧光 ,退行萎缩区呈斑驳样荧光 ,均伴周边小血管闭塞及无灌注区 ,后极部可见散在脉络膜炎性病变。结论 :FFA有助于了解病变的性质和范围 ,有助于诊断。

Objective:To evaluate the features of acute retinal necrosis syndrome.Method:16 patients (21 eyes) with acute retinal necrosis syndrome (ARN) were examined with fluorescein angiography (FFA),and the angiograms were analysed for the features of ARN.Results:Optic discs in all patients showed hyperfluorescent,and major retinal arterial branches were attenuated with sheathing,and showed delayed filling.There was occlusion in one major arterial branch.Retinal veins were tortuous,stained with dye,and showed leakage.Retinal necrosis foci,which showed uneven hypofluorescent in early stage of FFA and hyperfluorecent in later stage,were seen mostly in the peripheral retina.Atrophic areas showed mottled fluorescent,and were accompanied with occluded arterioles and non perfusion areas.Choroidal inflammatory foci scattered over the posterior retina.Conclusion:FFA is useful to understand the nature and extent of the retinal lesions and also helpful to make a correct diagnosis of ARN,but one should be careful to differentiate ARN from cytomegalovirus retinitis
