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.

Abstract
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.
