In a previous report on quantitative analysis of smooth pursuit eye movements (SPEM) we assessed two equations in order to describe the SPEM gain/target velocity relationship, and we demonstrated that this relationship is age-related. This report presents a method to evaluate normality of a single subject SPEM performance. Three points have been considered: 1) The control of gain asymmetries depending on target direction (leftward vs rightward SPEM) 2) The definition of age-related control values 3) The subject vs control values comparison An example to explain how our method actually works and its clinical applicability is shown. Finally, the reasons why no choice has been made between the two equations are discussed.
在之前一篇关于平稳跟踪眼球运动（SPEM）定量分析的报告中，我们评估了两个方程以描述SPEM增益/目标速度关系，并证明了这种关系与年龄相关。本报告提出了一种评估单个受试者SPEM表现正常性的方法。考虑了三点：1）根据目标方向（向左与向右SPEM）对增益不对称性的控制；2）与年龄相关的对照值的定义；3）受试者与对照值的比较。给出了一个例子来说明我们的方法实际如何运作及其临床适用性。最后，讨论了未在两个方程之间做出选择的原因。
