Monocular horizontal and vertical eye movements were recorded by electronystagmography (ENG) using silver plate electrodes in normal subjects. The amplitudes of horizontal or vertical eye movement were measured. Horizontal and vertical pursuit movements and saccades were recorded to measure their amplitudes. 1. Horizontal eye movement Amplitudes of the right eye=amplitudes of the left eye…55%, amplitudes of the right eye≠amplitudes of the left eye…45%. 2. Vertical eye movement Amplitudes of the right eye=amlitudes of the left eye…80%, amplitudes of the right eye≠amplitudes of the left eye…20%. In particular, the amplitudes of the horizontal right eye movement are not always equal to those of the left eye, therefore observation of ophthalmoplegia with ENG should be made very carefully.
