中心性浆液性脉络膜视网膜病变的光学相干断层扫描

Optical coherence tomography in central serous choroidoretinopathy

目的 评价光学相干断层成像术（ｏｐｔｉｃａｌｃｏｈｅｒｅｎｃｅ ｔｏｍ ｏｇｒａｐｈｙ，ＯＣＴ）对中心性浆液性脉络膜视网膜病变的诊断及追踪观察的临床使用价值。 方法 对３０ 例（３２ 只眼）中心性浆液性脉络膜视网膜病变患者分别进行检眼镜、荧光素眼底血管造影、ＯＣＴ检查。部分病例进行定期的光学相干断层成像术复查。 结果 ３２只眼中心性浆液性脉络膜视网膜病变的ＯＣＴ图像中，２７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，３只眼同时存在神经上皮层脱离和色素上皮层脱离。１１只眼定期追踪观察的ＯＣＴ均可动态地观察到液体的吸收和测量到神经上皮层脱离高度的减少。 结论 ＯＣＴ是一种新的、无损伤性的、非接触性和定量的检查方法。能鉴别中心性浆液性脉络膜视网膜病变的神经上皮层脱离和色素上皮层脱离，并能进行定量的追踪观察。

Objective To asses the potential of a new imaging technique,opticl coherence tomography(OCT),for diagnosis and monitoring of central serous choroidoretinopathy(CSC). Methods Thirty cases (32eyes) with CSC were examined by ophthalmoscopy,fundus fluorescein angiography and OCT. Some patients were monitored by OCT. Results Among images of OCT in 32 eyes with CSC,27 eyes showed serous neurosensory detachement,2 eyes appeared retinal pigment epithelial detachement and 3 eyes combined neurosensory detachement with pigment epithelial detachement.Monitoring images of OCT in ll 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.
