Quantitative analysis of slow eye movements with an IBM/AT compatible personal computer in the diagnosis of multiple sclerosis.

A self-developed software program is presented, by means of which it is possible to make routine recordings and automated analysis of slow eye movements in patients with suspected multiple sclerosis. The menu-guided program runs on an IBM/AT compatible personal computer and allows on-line survey of slow eye movements. Furthermore, interactive evaluation of the data is possible. Hard copies can be made from interesting slow eye movements and their calculated parameters. Finally, tables containing various parameters such as gain, pursuit amplitude, phase difference and number of corrective saccades as well as some simple statistical calculations can be printed out.
