Abstract

Analysis of eye movements is essential for investigating vestibular disturbances. Video-oculography, although expensive, is a valuable and sensitive tool that allows accurate estimation of eye movements. We describe a simple and inexpensive method of recording as well as analysing eye movements using a commercially available miniature digital video surveillance camera and an MP4 digital media recorder.
