Abstract

We devised a new analysis technique to display the nystagmus as an arrow based on the material for the standard examination of equilibrium. Three-dimensional eye movement image analysis was performed automatically using the public domain software ImageJ and a personal computer. The direction, amplitude and frequency of nystagmus were calculated from the result of horizontal, vertical and torsional components. The amplitude and frequency were classified into three phases based on the material for the standard examination of equilibrium. Using this technique, it was possible to display properties of the nystagmus as an arrow in detail on the computer.
