Adaptive programming of phasic and tonic components in saccadic eye movements. Investigations of patients with abducens palsy.

Abstract

Two patients with unilateral abducens palsy used their paretic-but visually superior-eye for fixation. In these patients, adaptive changes of saccadic amplitude and of the relation between phasic and tonic components of saccades were found. These changes led to a reduction of foveation time.
