牵牛花综合症的荧光素眼底血管造影分析

Fundus Fluorescein Angiography of Morning Glory Syndrome

目的分析牵牛花综合症的眼底表现及荧光素眼底血管造影(FFA)特征.方法收集云南省红十字会医院诊治的牵牛花综合症13例患者,进行眼底照相及FFA检查,进行对比分析.结果眼底特征性表现为,眼底可见增大的视乳头呈漏斗形凹陷,其被环形脉络膜视网膜萎缩灶包围.视乳头中央为白色簇状白色胶质样组织.视网膜血管自视乳头凹陷边缘呈放射状发出,其数量增加,动静脉难辨.FFA特征为:漏斗状凹陷中心的白色组织遮蔽荧光或弱荧光,其外为环形强荧光,最外圈为透见荧光,一般少见荧光渗漏.结论眼底检查、FFA检查结合患者病史可明确诊断牵牛花综合症.

Objective To analyze the fundus characteristics and fluorescein angiography of morning glory syndrome.Methods The morning glory syndrome patients＇ fundus photography and fundus fluorescein angiography were analyzed in our hospital.Results Fundus examination showed： a large disc with a funnel-shaped excavation surrounded by an annulus of choriorretinal atrophy.A white tuft of glial tissue overlies the central portion of disc.The blood vessels emerged from the rim of excavation in a radial pattern,and they increased in number and it was difficult to distinguish arteries from veins.Angiographic characteristics： in the central of disc the white tissue was blockage of fluorescence or hypofluorescence which was surrounded by is hyperfluorescence,and at the outside is transmitted fluorescence.It＇s rarely to see fluorescein leakage.Conclusion The fundus examination,fundus fluorescein angiography and combination of patients＇ history are helpful to confirm the diagnosis of morning glory syndrom.
