A 38-year-old woman developed intermittent oscillopsia occurring every 45 to 90 minutes and lasting 20 to 40 seconds. She had a right-beating jerk nystagmus during these episodes. At other times, her neurologic examination was normal, and no nystagmus could be elicited. The nystagmus resolved when her classic migraine headaches were controlled with medical therapy. This intermittent unidirectional nystagmus may represent dormant periodic alternating nystagmus or another type of dormant nystagmus appearing intermittently due to episodic migrainous brainstem ischemia.
一名38岁女性出现间歇性视振荡，每45至90分钟发作一次，持续20至40秒。发作期间她有向右跳动的眼球震颤。其他时候，她的神经系统检查正常，未引出眼球震颤。当她的典型偏头痛通过药物治疗得到控制时，眼球震颤消失。这种间歇性单向眼球震颤可能代表潜伏性周期性交替性眼球震颤，或由于发作性偏头痛性脑干缺血而间歇性出现的另一种潜伏性眼球震颤。
