Video-based eye tracking techniques are a useful methodology for physiological
recording of saccades. Saccades are fastest eye movements having the purpose of repositioning the
fovea on new target in the visual scene. Laboratory conditions enable stereotyped eye movements and
reproducible results that can provide insights into normal and abnormal saccades particularly in
neurodegenerative diseases. We discuss the methods and design that produced a consistent normal
data set of saccadic parameters and coefficients of main sequence relationships.
