Research advances on mechanism and lesion location of vertical nystagmus / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Summary@#Vertical nystagmus is a vertical nystagmus caused by structural abnormalities and/or dysfunction of the central vestibular system and observed in situ in the center of the eyeball. There are two kinds of nystagmus （UBN） and downbeat nystagmus （DBN） according to the direction of nystagmus. The diagnosis of UBN is mainly made by naked eye or electronystagmography/viewer. It is a common neuro-ophthalmologic sign in the field of vestibular medicine. In this paper, the mechanism of vertical nystagmus formation and the location of lesions were briefly introduced, in order to provide help for the diagnosis and treatment of Vertigo.
