中心性浆液性脉络膜视网膜病变的光学相干断层扫描与视力的相关性研究

The relation of the vision decrease and optical coherence tomography with central serous chorioretinopathy

目的探讨中心性浆液性脉络膜视网膜病变浆液性脱离区的光学相干断层扫描与视力的关系。方法对48例(50只眼)经FFA诊断为中心性浆液性脉络膜视网膜病变的患者行OCT检查,对浆液性脱离区进行测量并与视力进行相关分析。结果光学相干断层扫描图像可以清晰显示浆液性脱离性质、部位、高度、宽度。48 例(50只眼)结果分析显示:患者视力与浆液性脱离区的高度、范围、中心凹6．0mm容积有关,与中心凹的厚度无关。结论 OCT能显示中心性浆液性脉络膜视网膜病变患者的病变直观图像并能观察病情程度。对随访病情变化有指导意义。

Objective To evaluate the use of optical coherence tomography （OCT） in analysis of the vision decrease with eentral serous chorioretinopathy（CSC）. Methods we studied 48 patients with CSC using OCT. And correlation analysis among the vision with four values was made. Results The OCT imagines show serous detachinent of CSC, including serous neurosensory detachment and serous pigment epithelial detachment. The negative correlation was showed between vision with size and height of serous detachment and macular valume. Conclusion Optical coherence tomography is potentially useful as a new, noninvasive diagnostic technique for quantitative examination of patients with central serous chorioretinopathy and Objectively monitoring the clinical course of the serous retinal detachment in this disease. The main factors influencing vision are size, macular valume and height of serous detachment.
