Principles of Electronystagmography Based on Dipole Theory

Abstract

Principles of eye recording in electronystagmography (ENG) have been established phenomenologically on the basis of the experimental results of Mowrer, Ruch and Miller (1936). However, unexpected recordings, for example, so-called pseudo-eye-movements, may be experienced in clinical use. These have been described from the phenomenological view point in the author's previous reports.
In this study, a theoretical equation to predict eye positions and eye movements on the basis of a dipole theory is presented. Comparison between the predicted eye movements and the record of eye movements in ENG revealed fairly a good agreement. It is assumed that the equation has values to predict eye movements in ENG and to support the principles of electronystagmography as explained by the dipole theory.
