Abstract
Recording and quantifying eye movement is the basis of audiologic balance testing. The ability to record and quantify eye movement is a key part of the electronystagmography (ENG) test battery. With computerization, eye movements can be more accurately detected and analysed - testing the limits of the standard recording technique. In response to this, manufacturers are introducing alternative recording protocols. Specifically, infra-red video technology allows an accurate and sophisticated recording and analysis of eye motion in response to balance-related stimuli. The purpose of this technical note is to discuss the limitations of the EOG recording method and discuss the advantages that video-oculography offers.
