特发性中心性浆液性脉络膜视网膜病变的光学相干断层成像

Optical coherence tomography in idiopathic central serous chorioretinopathy

目的 探讨特发性中心性浆液性脉络膜视网膜病变 ( idiopathic central serous chorioretinopathy,IC-SC)光学相干断层成像术 ( optical coherence tomography,OCT)改变的诊断特点与其临床应用价值。方法 对临床上诊断为 ICSC的 40例 ( 41只眼 )患者做 OCT和荧光素眼底血管造影检查、测量和分析。结果 40例 ( 41只眼 ) IC-SC的 OCT图像均表现为黄斑中心的视网膜神经上皮层局限性脱离 ,脱离范围在 70 5～ 5 72 0 μm(平均 3 0 5 0 .80 49±13 3 7.5 619μm) ,高度 5 5～ 491μm(平均 2 69.85 3 7± 114.2 796μm)。 4只眼合并有色素上皮层浆液性脱离。并经统计表明脱离范围、高度与视力相关。结论 OCT作为一种客观的无损伤的视网膜断层扫描技术 ,其高分辨率的特性在 ICSC的诊断。

Objective To study the characteristics and clinical values on idiopathic central serous chorioretinopathy(ICSC) with optical coherence tomography.Methods In this study,41 eyes of ICSC were evaluated with optical coherence tomography and fundus flourescein angiography.The foval thickness was measured by optical coherence tomography.Results In ICSC OCT showed the serous retinal detachment in fovea area of macular in all 41 eyes.The range of detached area with ICSC is 705～5720μm(mean 3050.8049±1337.5619μm),and its height was 55～491μm(mean 269.8537±114.2796μm).In addition,4 eyes also presented the detachment of pigmented epithelial.It showed that the visual acuity was relative to the amount of the detached height and range.Conclusion The studies of ICSC with OCT showed that the serous neurosensory retinal detachment was seen in all the cases in the acute phase.OCT was useful as a noninvasive diagnostic technique for quantitative examination and objectively monitoring the clinical course of the serous retinal detachment in this disease.
