Abstract

Background: Severe hypomagnesemia is an increasingly recognized cause of acute and reversible cerebellar ataxia, often accompanied by cerebellar oculomotor signs such as jerky horizontal or downbeat nystagmus and very rarely ocular flutter.

Phenomenology shown: This video illustrates horizontal pendular nystagmus in a patient with acute onset cerebellar ataxia associated with severe hypomagnesemia.

Educational value: Acquired pendular nystagmus can be distinguished from macrosaccadic oscillations and ocular flutter in that the former is composed of two slow phases of equal velocity and the latter of two fast phases of saccadic type with or without intersaccadic interval, respectively. It is most commonly associated with demyelinating, toxic, metabolic, and genetic disorders, but has not been reported in association with severe hypomagnesemia.

继发于严重低镁血症的水平垂性眼球震颤和共济失调。
背景:严重的低镁血症是越来越多的人认识到的急性和可逆性小脑共济失调的病因,通常伴有小脑眼球运动症状,如生涩的水平或下垂眼球震颤,极少数情况下伴有眼球扑动:这段视频展示了一名急性小脑共济失调伴严重低镁血症患者的水平下垂性眼球震颤:后天性下垂性眼球震颤可与大视野振荡和眼扑区分开来,前者由两个等速的慢相组成,后者由两个囊状的快相组成,分别有或没有囊状间歇。它最常见于脱髓鞘疾病、中毒性疾病、代谢性疾病和遗传性疾病,但尚未见与严重低镁血症有关的报道。
