目的:探讨并发糖尿病视网膜病变(DR)的2型糖尿病患者与健康人群脉络膜血管指数(CVI)的差异及特点。方法:选取2017-01/12于我院就诊的并发DR的2型糖尿病患者68例68眼作为DR组,同时纳入同期体检的无糖尿病病史健康人群34例34眼作为对照组...目的:探讨并发糖尿病视网膜病变(DR)的2型糖尿病患者与健康人群脉络膜血管指数(CVI)的差异及特点。方法:选取2017-01/12于我院就诊的并发DR的2型糖尿病患者68例68眼作为DR组,同时纳入同期体检的无糖尿病病史健康人群34例34眼作为对照组。通过频域相干光层析深度增强成像术(EDI-OCT)获取受检者黄斑中心凹下脉络膜厚度(SFCT)、黄斑中心凹处视网膜厚度(CRT),并将黄斑区图像进行二值化处理,采用图像分析软件计算黄斑区脉络膜总面积(TCA)、血管区面积(LA)及间质区面积(SA),计算CVI。结果:对照组和DR组受检者TCA(0.53±0.14mm2 vs 0.49±0.15mm2)、LA(0.35±0.09mm2 vs 0.32±0.10mm2)、SA(0.17±0.05mm2 vs 0.17±0.06mm2)及SFCT(347.9±76.9μm vs 325.9±92.9μm)均无差异(P>0.05),但DR组患者CVI明显低于对照组(64.33%±3.25%vs 67.04%±2.46%,P<0.001),二者临界值为63.59%。结论:CVI可以直观反映脉络膜内部结构的变化,较SFCT更加稳定可靠,合并DR的2型糖尿病患者其CVI较健康人群降低。展开更多
