We studied horizontal saccades by direct-current electro-oculography in 18 patients with internuclear ophthalmoplegia (INO), and in 16 healthy, age-matched subjects. The occurrence of abducting signs, i.e. overshoot and dissociated nystagmus, was related to an increase of interocular dissociation (measured by the ratio of abduction and adduction peak velocities). The amplitude of abduction hypermetria was strongly correlated with the intensity of adduction slowing. These findings support the idea of an adaptive mechanism underlying the overshoot and nystagmus of abduction saccades in INO.
我们通过直流电眼震图研究了18例核间性眼肌麻痹（INO）患者及16名年龄匹配的健康受试者的水平扫视。外展征（即过冲和分离性眼震）的出现与眼间分离增加（通过外展和内收峰值速度之比测量）有关。外展性辨距过度的幅度与内收减慢的程度密切相关。这些发现支持了INO中外展扫视过冲和眼震背后存在适应性机制的观点。
