A new laser Doppler system for the noninvasive examination of the human optic nerve head microcirculation is described. The electro-optical component of the system consists of a retinal camera modified with laser input optics and a fiber optic light detection system for collection of the Doppler-shifted scattered light. Data acquisition is carried out in real time under computer control. Automated analysis of the data provides a quantitative measure of the speed of blood cells flowing through the capillaries of the optic nerve head. Unlike previous systems, this system provides results within a few minutes following data acquisition. It is thus appropriate for use in a clinical setting. Analysis of multiple measurements on a patient shows a coefficient of variation of 8.9%. © 1998 Society of Photo-Optical Instrumentation Engineers.
描述了一种用于人体视神经乳头微循环无创检查的新型激光多普勒系统。该系统的电光组件包括一个经激光输入光学器件改装的视网膜相机和一个用于收集多普勒频移散射光的光纤光检测系统。数据采集在计算机控制下实时进行。对数据的自动分析提供了流经视神经乳头毛细血管的血细胞速度的定量测量。与以前的系统不同,该系统在数据采集后几分钟内就能得出结果。因此,它适用于临床环境。对患者进行多次测量的分析显示变异系数为8.9%。© 1998 美国光电仪器工程师协会。
