Abstract

The measurement of eye movements in three dimensions is an important tool to investigate the human oculomotor system. When compared with the conventional electro-nystagmography (ENG) and scleral search coil system (SSCS), the video-oculography (VOG) has a higher accuracy and is a more comfortable and reliable method for the 3D-measurement of human eye movements.

Keywords: Electro-nystagmography, Eye movement, Recording technique, Search coil, Video-oculography
