前庭功能障碍对凝视稳定性的影响,曾经深入地研究。人类由单侧病灶引起凝视障碍可于一年内恢复,此与减少前庭-眼反射(VOR)的不平衡相一致,可由向患侧旋转,增进VOR来测出。然而双侧病变所引起的凝视障碍是难以代偿的,振动幻视的程度因人而有显著差别,并随着时间而自觉减轻。本文的目的是为了了解双侧前庭病变获得代偿所需的时间及进行程度。在主动和被动的旋转下,观察前庭-眼反射获得短期和长期变化和凝视能力。15例双侧前庭功能丧失患者于病后从一月至34年间,在不同时期接受自动和被动的旋转试验,结果克服了凝视障碍。在主动旋转下相对于时间的对数,平均前庭-眼反射获得很快增加,而被动旋转则增加很慢。病后第一年在主动和被动旋转刺激下,凝视障碍得以克服。主动旋转的结果,在高频率时对凝视
The effect of vestibular dysfunction on gaze stability has been studied in depth. Strabismus caused by unilateral lesions in humans can recover within one year, consistent with the reduction of vestibular-ocular reflex (VOR) imbalance, which can be measured by increasing the VOR to the affected side. However, bilateral lesions caused by gaze disorders are difficult to compensate, the degree of vibration visual field due to significant differences, and consciously reduce over time. The purpose of this article is to understand the timing and extent of bilateral vestibular disease compensated. Under active and passive rotation, observe vestibular-ocular reflexes for short-term and long-term changes and gaze. Fifteen patients with bilateral loss of vestibular function underwent automatic and passive rotation tests at different times from January to 34 years after the illness, resulting in overcoming gaze disorders. The average logarithm of the vestibular-ocular reflex increases rapidly with active rotation versus time, whereas passive rotation increases slowly. In the first year after the illness, active and passive rotational stimulation, gaze disorders can be overcome. Active rotation results in gaze at high frequencies
