肥胖与视网膜微血管功能障碍有关. 胰岛素抵抗的恒温模型评估 (HOMA-IR) 评分显示,作为预测肥胖患者这种功能障碍的生物标志物具有前途.

科学领域:

眼科医生眼科眼科
内分泌学在内分泌学.
血管生物学血管生物学

背景情况:

肥胖与微血管功能障碍有关,影响视力敏度.
视网膜微血管变化,特别是视神经头部 (ONH),与视力障碍有关.
胰岛素抵抗是肥胖中常见的代谢异常.

研究的目的:

调查肥胖患者的胰岛素抵抗 (HOMA-IR) 恒温模型评估得分和ONH微血管功能障碍 (毛细血管输液和流量指数) 之间的关系.
评估HOMA-IR在预测视网膜血管功能障碍方面的诊断性能.

主要方法:

一项涉及160名肥胖和非肥胖个体的病例控制研究.
用HOMA-IR从禁食葡萄糖和胰岛素水平中获得的评估胰岛素耐药性.
光学连贯断层扫描血管造影 (OCT-A) 用于测量ONH毛细血管 perfusion 和流量指数.
用于统计分析的皮尔森相关性,ROC曲线分析和物流回归.

主要成果:

HOMA-IR得分与上方,下方和外部区域的ONH毛细血管输液有显著的负相关.
在上部,下部,鼻腔和外部区域,HOMA-IR得分与ONH流量指数显著负相关.
5.51的HOMA-IR切线显示了检测血管功能障碍的AUC为0.819,在多个ONH区域中发现了显著的关联.
