    目的　评价光学相干断层成像术(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只眼)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。部分病例复查时再次进行光学相干断层成像术检查。　

    结果　45只眼中心性浆液性脉络膜视网膜病变的OCT 图像，42只眼表现为单纯神经上皮层脱离,2只眼为单纯色素上皮层脱离, 1只眼同时存在神经上皮层脱离和色素上皮层脱离。9只眼复查的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。

    【Abstract】　Objective　To asses the potential of a new imaging technique, opticl coherence tomography (OCT )for diagnosis of central serous choroido retinopathy (CSC). Methods Forty-five cases (45eyes) with CSC were examined by ophthalmo scopy, binocular indirect ophthalmoscope and OCT.Some patients were monitored by OCT. 　Results　Among images of OCT in 45 eyes w ith 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. 　Conclusions　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.
