Abstract
Analysis of nystagmus using manual methods is time consuming, reliant on considerable experience and subject to observer bias. Like many electrophysiological responses, nystagmus waveforms are suited to acquisition and analysis by digital computer techniques. Development of computerized eye movement analysis procedures commenced in the late 1960s. Initially programs were mostly research-based with the data often acquired on FM tape recorders and evaluated on mini-computers. As computer technology evolved and equipment prices decreased, development of portable software and hardware for use in general clinical assessment became feasible. The development of computer programs for the acquisition and analysis of eye movements is described and the limitations of analysis procedures discussed.
