观察中心性浆液性脉络膜视网膜病变(CSC)患者的光学相干断层扫描血流成像(OCTA)图像特征

Optical Coherence Tomography(OCTA)Imaging Features were Observed in Patients with Central Serous Chorioretinopathy(CSC)

目的:对中心性浆液性脉络膜视网膜病变(CSC)患者进行光学相干断层扫描血流成像(OCTA)检查,并分析其图像特征。方法:选取2018年8月~2020年7月,在本院治疗的33例CSC患者作为观察组,同时,选择33例健康体检者作为对照组。所有受检者均进行OCT、OCTA检查,分析两组受检者的SFCT及OCTA图像特征。结果:观察组患者患侧眼的SFCT明显大于对侧眼及对照组对照眼,对侧眼的SFCT同样大于对照组对照眼(P<0.05);观察组33只患侧眼,脉络膜毛细血管层OCTA检测显示血流信号异常96.97%,对侧眼为39.39%,对照眼均血流信号正常,差异明显(P<0.05)。结论:OCTA可准确测量SFCT厚度,获取脉络膜毛细血管层血流特征信息,具有较高应用价值。

Objective:To conduct OCTA examination and analyze the image characteristics of CSC patients.Methods:33 patients with CSC treated in our hospital from August 2018 to July 2020 were selected as the observation group,and 33 healthy physical examination subjects were selected as the control group.All the subjects underwent OCT and OCTA examination,and the SFCT and OCTA image characteristics of the two groups of subjects were analyzed.Results:SFCT of the affected eye in the observation group was significantly larger than that of the contralateral eye and the control eye,and SFCT of the contralateral eye was also larger than that of the control eye(P<0.05).In the observation group,there were 33 affected side eyes.OCTA test of choroid capillary layer showed abnormal blood flow signal of 96.97%,and that of the contralateral eye was 39.39%.Blood flow signal of the control eyes was normal,with significant difference(P<0.05).Conclusion:OCTA can accurately measure the thickness of SFCT and obtain the blood flow characteristic information of choroid capillary layer,which has high application value.
