Horizontal jerk nystagmus is indicative of a disorder involving the vestibular system. Periodic alternating nystagmus is a form of spontaneous nystagmus with a specific pattern. It is identified by the presence of spontaneous nystagmus in the primary direction of gaze, which beats in one direction for 1 or 2 minutes, followed by a null period, and then reappearance of the nystagmus in the opposite direction for a similar length of time. It may be congenital or acquired, and may be seen in association with vestibular-cerebellar disease or loss of vision. Recent case reports indicate that some forms of periodic alternating nystagmus may respond favorably to baclofen therapy.
水平性急跳性眼球震颤提示存在涉及前庭系统的疾病。周期性交替性眼球震颤是一种具有特定模式的自发性眼球震颤形式。它通过在主要注视方向上出现自发性眼球震颤来识别，该眼球震颤向一个方向跳动1或2分钟，随后有一个无眼球震颤期，然后眼球震颤以相反方向再次出现并持续相似的时长。它可能是先天性的或后天获得的，并且可能与前庭小脑疾病或视力丧失有关。最近的病例报告表明，某些形式的周期性交替性眼球震颤可能对巴氯芬治疗反应良好。
