摘　　要：目的探讨中心性浆液性脉络膜视网膜病变患者脉络膜毛细血管扩张和黄斑中心凹下脉络膜厚度的关系。方法选取2015年2月至2016年4月我院收治的中心性浆液性脉络膜视网膜病变患者84例(84眼),依据荧光素眼底血管造影检查结果分为3组:轻度组(注射后9~10 min渗漏)26例,中度组(注射后5~8 min渗漏)37例,重度组(注射后5 min内渗漏)21例,利用OCTA技术确定脉络膜毛细血管扩张程度,利用EDI-OCT测量3组患者以及脉络膜毛细血管不同扩张程度下患者的黄斑中心凹下脉络膜厚度,并进行相关性分析。结果轻度、中度、重度患者的脉络膜毛细血管重度扩张比例依次升高(7.69%、13.52%、23.81%),黄斑中心凹下脉络膜厚度依次增加,差异具有统计学意义(P<0.05)。脉络膜毛细血管轻度、中度、重度扩张患者的黄斑中心凹下脉络膜厚度分别为(306.59±74.18)μm、(367.21±85.04)μm、(416.27±104.56)μm,差异具有统计学意义(P<0.05)。中心性浆液性脉络膜视网膜病变患者患侧脉络膜毛细血管扩张程度与黄斑中心凹下脉络膜厚度明显正相关(r=0.812,P=0.037)。结论随着病情的加重,中心性浆液性脉络膜视网膜病变患者脉络膜毛细血管扩张程度和黄斑中心凹下脉络膜厚度明显增加,且二者存在明显的正相关关系。Objective To investigate the relationship between choroidal telangiectasia and subfoveal choroidal thickness in the patients with central serous chorioretinopathy. Methods Eighty-four patients （84 eyes） with central serous chorioretinopathy in our hospital from February 2015 to April 2016 were selected,based on the fluorescein angiography the patients were divided into 3 groups：Mild group （leakage at 9 - 10 minutes after injection,26 cases） ,moderate group （leakage at 5 -8 minutes after injection,37 cases） ,severe group （leakage at 5 minutes after injection,21 cases）. The cho- roidal capillary dilatation was assessed by OCTA, and subfoveal choroidal thickness in three groups and patients with different foveal choroidal expansion degree were meas- ured by EDI-OCT,and correlation analysis was performed. Results The proportion of severe dilation of choriocapillae in mild group, moderate group, severe group were 7.69% , 13.52% and 23.81% , respectively. The subfoveal choroidal thickness was sequentially increased in mild group ,moderate group ,severe group （P 〈 0.05 ）. The subfoveal choroidal thickness in patients with mild,moderate and severe dilatation of choroidal capillaries were （306.59 ± 74. 18 ） μm, （367.21 ± 85.04 ） μm and （416. 27 ± 104.56） μm, respectively （P 〈 0.05 ）. The degree of choroidal telangiectasia in patients with central serous chorioretinopathy had a positive correlation with the thickness of subfoveal choroid （ r = 0.812 ,P = 0. 037 ）. Conclusion The degree of choroidal telangiectasia and subchondral choroidal thickness in patients with central serous chorioretinopathy are significantly increased with the severity of the disease,and there is a positive correlation between them.
