脉络膜渗漏综合征的眼底血管造影特征

Characteristics of images of angiography in uveal effusion syndrome

目的观察脉络膜渗漏综合征（UEs）的眼底血管造影特征。方法回顾分析UES患者11例17只眼荧光素眼底血管造影（FFA）及吲哚青绿血管造影（ICGA）检查的临床资料。其中7只眼在作巩膜板层切除手术后1～28个月再行造影检查。结果FFA及ICGA检查显示12只眼有视网膜静脉纡曲扩张及视盘水肿，2只眼在后极部出现荧光素渗漏点，14只眼有豹纹样色素斑（豹斑），8只眼有线条状或网状色素条纹。ICGA检查4例5只眼的斑片状强荧光一直持续至晚期，1只眼在眼底下方有三角形弱荧光区，1只眼在后极部显示地图状弱荧光区。巩膜板层切除手术后患眼睫状体脉络膜脱离逐渐好转甚至消失，脉络膜高灌注状态改善，渗漏点消失。1只眼手术2年后视网膜下液又增多。结论视网膜静脉纡曲扩张及视盘水肿、豹斑和线条状或网状色素条纹是UES的特征性眼底血管造影表现；这些表现有助于加深对此病的理解和临床诊断。

Objective To investigate the characteristics of images of angiography in uveal effusion syndrome （UES）. Methods The clinical data of fundus fluorescein angiography （FFA） and indocyanine green angiography （ICGA） in 11 patients （17 eyes） with UES were retrospectively analyzed, and 4 patients （7 eyes） underwent angiography again 1 month to 28 months after segmental sclerectomy. Result The results of FFA and ICGA showed papilledema and venous tortuosity and dilation in 12 eyes, leakage spots at the post pole of ocular fundus in 2 eyes, leopard spots in 14 eyes, linear or meshy pigment stripes in 8 eyes. The results of ICGA showed uneven flecked hyperfluorescence lasted to later stage in 4 patients （5 eyes）, a triangle hypofluorescence area at the inferior fundus in 1 eye, and a geographic pattern hypofluorescence at the posterior pole in 1 eye. Segmental sclerectomy was performed on 5 patients （8 eyes）, and after surgery, cilia-choroidal detachment was gradually alleviated and even disappeared, the status of choroidal hyperpermeability was alleviated, and the leakage spots disappeared. The subretinal fluid increased in only 1 eye 2 years after the surgery. Conclusion The characteristics of aniography for UES are venous tortuosity and dilation, papilledema, leopard spots, and linear or meshy pigmentary stripes, which may deepen our understanding about the disease and help to diagnose it.
