Abstract］ objective to assess a new imaging technique,optical coherence tomography,for the diagnosis of central serous choroidoretinopathy.methods forty-five cases (45 eyes) of csc were examined by ophthalmoscopy,binocular indirect ophthalmoscopy and oct.some patients were monitored by oct.results in images of oct in 45 eyes of csc,42 eyes showed serous neurosensory detachement,2 eyes appeared retinal pigment epithelial detachement and 1 eyes combined neurosensory detachement with pigment epithelial detachement.monitoring images of oct in 9 eyes revealed absorption of serous fluid and decrease of neurosensory detachment.conclusion oct is potentially useful as a new and noninvasive diagnostic technique for quantitative examination of patients with csc and objectively monitoring the clinical course of the serous retinal detachement in this disease.

摘要］ 目的评价光学相干断层成像(optical coherence tomography，oct )对中心性浆液性脉络膜视网膜病变的临床诊断价值。方法对45例(45眼)中心性浆液性脉络膜视网膜病变患者散瞳后分别进行直接检眼镜、双目间接检眼镜、oct 检查。9例复查时再次进行oct检查。结果 45眼中心性浆液性脉络膜视网膜病变的oct 图像，42眼表现为单纯神经上皮层脱离，2眼为单纯色素上皮层脱离，1眼同时存在神经上皮层脱离和色素上皮层脱离。9眼复查的oct通过测量脱离高度的降低可观察到液体的不同程度吸收。结论 oct 是一种新的、无损伤性的、非接触性的、并能定量的检查方法，能明确中心性浆液性脉络膜视网膜病变的脱离部位，并能进行定量的追踪观察。
