科学领域:

眼科医生和光学学家的眼科和光学.
生物医学工程生物医学工程
公共卫生公共卫生

背景情况:

视网膜血管参数作为眼睛和全身健康的潜在生物标志物.
建立规范范围对于解释单个测量和识别偏差至关重要.

研究的目的:

为了确定一系列视网膜血管测量的规范范围.
评估这些测量作为眼睛和全身健康的生物标志物的实用性.

主要方法:

这是一项涉及来自英国生物银行的10,151名健康参与者的横截面研究.
利用基于视网膜的微血管健康评估系统软件,提取 114 个视网膜血管测量 (口径,复杂度,密度,分支角度,扭曲度) 的动脉和静脉.
探索了视网膜测量和健康指标之间的关联,如年龄,静脉血压 (SBP),体重指数,糖化血红蛋白和眼内压力.

主要成果:

为114个视网膜血管测量提供了人口规范范围,按性别和年龄分层.
确定年龄和SBP与大多数视网膜参数具有最强的关联.
观察到中央视网膜动脉等价,中央视网膜静脉等价 (CRVE),密度和复杂性随着年龄和SBP的增加而下降,动脉测量显示出更大的变化.

结论:

已确定的人口规范数据用于全面的视网膜血管测量.
允许量化方法,以更好地了解视网膜血管变化及其对健康的影响.
