[Micromovements of the eyes in isolated pareses and paralyses of the abducens and oculomotor nerves].
Micromovements of the eye were studied in 18 patients with immobile point fixation, without a point, with an extreme eye abduction. A reduction of the number of involuntary saccades attributable to the paralyzed muscle, and increase in frequency and in the amplitude of the drift were revealed. The above changes in the micromotions of the eye correlate with the volume of the movement; the less the volume of the movement, the less the number of saccades and the larger the amplitude and the frequency of the drift. At the same time the characteristics of fast movements changed (involuntary jerks, reflex saccades and and saccades of the extreme position), the latter also correlating with the volume of the movements; along with the reduction of the volume of the movement the amplitude was decreasing as low as disappearing.
