对于大多数测量,三个眼部生物计显示出高可重复性. 然而,显著差异和固定偏差的平均值在设备之间并不能完全互换,这会影响临床解释.
科学领域:
- 眼科医生 眼科 眼科
- 生物医学工程 生物医学工程
- 医疗器械技术 医疗器械技术
背景情况:
- 准确的眼部生物识别对于解释测量非常重要.
- 广泛的生物识别设备需要直接比较一致性和可重复性.
研究的目的:
- 评估三种眼部生物计的设备内部可重复性和设备间一致性.
- 为了比较IOLMaster 700,Galilei G6和Pentacam AXL的测量结果.
主要方法:
- 在大学医院,歌德大学,德国法兰克福,前性,比较研究.
- 使用IOLMaster 700,Galilei G6和Pentacam AXL对白内障眼睛进行连续测量.
- 对模拟角膜测量 (simK),纹测量 (simA),总角膜测量 (TC),轴长 (AL),前腔深度 (ACD) 和包膜测量 (CT) 的重复性和一致性的评估.
主要成果:
- 观察到simK,TC,AL和CT的高重复性 (ICC>0.9,COV<0.5) 值.
- 对simK,AL和TC的设备之间的显著平均差异 (p < 0.05).
- ACD和simA显示高ICC但较低的协议;布兰德-阿尔特曼图表显示simK的固定偏差,表明不可互换.
结论:
- 这三种设备对大多数测量变量具有非常高的重复性.
- 设备之间的固定差异表明,测量值不是完全可互换的.
- 为了准确的临床解释,需要仔细考虑特定于设备的值.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
