目的 观察急性中心性浆液性脉络膜视网膜病变(CSC)患眼渗漏点的频域光相干断层扫描(SD-OCT)的影像特征。 方法 临床检查确诊的急性CSC患者21例21只眼纳入研究。其中,男性17例17只眼,女性4例4只眼;平均年龄(47.3±8.8)岁。平均病程(1.6±0.8)个月。均行最佳矫正视力、裂隙灯显微镜、间接检眼镜、荧光素眼底血管造影(FFA)、SD-OCT检查。将SD-OCT检查显示的渗漏点形态归为视网膜色素上皮(RPE)突起、RPE脱离(PED)、神经上皮层下强反射区、RPE缺损等4种类型。对比分析FFA渗漏点及SD-OCT的影像特征。 结果 21只眼FFA检查共发现21个渗漏点。SD-OCT检查发现,21个渗漏点中,RPE突起10个,占47.6%;表现为RPE反射光带出现孤立的局限性隆起。PED 7个,占33.3%;表现为RPE层隆起,其下为液性弱反射暗区。神经上皮层下强反射区3个,占14.3%;表现为渗漏点部位神经上皮层下强反射区。RPE缺损1个,占4.8%。 结论 急性CSC患眼渗漏点SD-OCT影像特征为RPE突起、PED、神经上皮层下强反射区、RPE缺损。

Objective To observe the characteristics of spectral-domain optical coherence tomography (SD-OCT) for leakage point in acute central serous chorioretinopathy (CSC). Methods A total of 21 acute CSC patients (21 eyes) were enrolled in this retrospective study, including 17 men (17 eyes) and 4 women (5 eyes). The mean age was (47.3±8.8) years (range 35 - 66 years). The mean duration was (1.6±0.8) months (range 0.5 - 3.0 months). All patients were underwent mydriatic fundus photography, SD-OCT examination and fluorescein fundus angiography (FFA). SD-OCT and FFA images were carefully compared to observe the SD-OCT examination characteristics of fluorescence leakage point. Results 21/21 eyes had one fluorescein leakage point. In addition to serous retinal detachment, leakage point in the SD-OCT examination showed retinal pigment epithelium (RPE) protrusion in 10 eyes (47.6%), RPE detachment in 7 eyes (33.3%), highly reflective areas suggesting fibrinous exudate in the subretinal space in 3 eyes (14.3%), and RPE defect in 1 eye (4.8%). Conclusion The SD-OCT characteristics of acute CSC include RPE protrusion, RPE detachment, highly reflective areas suggesting fibrinous exudate in the subretinal space and RPE defect.
