Saccade control is a complex function of our brain and relies on the coordination of several subcortical and cortical structures. For a long time it has been difficult to use data from analysing saccades as additional diagnostic insight into a patientís problem. With the development of technical advantages and with progress of optomotor research there was a better understanding of the generation of saccades. This article describes the development of saccade control between age 7 to age 80y. The diagnostic methods consist of a comparison of individual data with those of age-matched healthy subjects. A large group of dyslexic subjects was used as an example. The effect of daily practice of saccade and fixation control and its transfer to reading skills will be described. It is concluded that the described methods add to the neurological battery of quantitative testing. Success of the training and its transfer to reading completes the use of the analysis of eye movements in neurology.
