An electrooculographic system for quantitive study of tracking eye motion is described. The tracking target is a projected spot of light which moves under computer control with different operator selectable constant accelerations. A single FORTRAN program with eleven subroutines, running on a PDP 11/40 computer in 22 K of memory, controls data collection and data analysis, as well as target movement. A number of quantitative parameters are extracted from the data, including smooth pursuit velocity, the correlation in movement between the two eyes and the maximum eye-target spot 'phase' difference in degrees. The relationship between smooth pursuit and saccadic eye movements can be visualised by storage and display of the instantaneous eye velocity during tracking manoeuvres. The system has proven very useful as an aid to diagnosis of some neurological disorders, particularly multiple sclerosis.
本文描述了一种用于定量研究跟踪眼球运动的眼电图系统。跟踪目标是一个投射光斑，它在计算机控制下以不同的、操作员可选择的恒定加速度移动。一个包含11个子程序的FORTRAN程序，在一台内存为22K的PDP 11/40计算机上运行，控制数据收集、数据分析以及目标移动。从数据中提取了许多定量参数，包括平稳跟踪速度、双眼运动的相关性以及以度为单位的最大眼-目标光斑“相位”差。通过在跟踪操作期间存储和显示瞬时眼球速度，可以直观地呈现平稳跟踪和眼球快速跳动运动之间的关系。该系统已被证明对某些神经系统疾病，特别是多发性硬化症的诊断非常有用。
