背景情况:

在健康个体中评估视网膜黄斑氧和度对于了解糖尿病等血管疾病至关重要.
局部视网膜氧度测试提供了对黄斑健康的见解.

研究的目的:

评估齐利亚氧度仪在健康成年人视网膜氧度测试中的测试重复性.
评估18-40岁不同种族群体的斑点氧和度测量结果.

主要方法:

27名健康的成年人 (平均年龄为26.3岁) 使用Zilia设备进行了视网膜氧计.
在四个黄斑位置进行测量,在同一天重复两次,并在1-2周后再次进行测量.
类内相关性,布兰德-阿尔特曼重复性系数和变化系数用于分析.

主要成果:

在三个测量时间的平均课内相关性为0.78.8.
平均人体内可重复系数为8.4,变化系数为5.4%.

结论:

齐利亚氧计表现出很好的测试-重复测试可重复性,用于斑点氧和度的测量.
虽然可重复,但临床医生可能需要获得多次读数,以确保视网膜氧计的准确性.
