Downbeat nystagmus is not rare and usually considered as a central nervous system disease. However, there are a lot of diseases that present with downbeat nystagmus only or downbeat component in nystagmus, including peripheral and central vestibular diseases and Chiari malformations. This review will briefly summarize the vestibulo ocular reflexes and the mechanisms of the downbeat nystagmus with a peripheral origin, and then common vestibular disease such as the anterior semicircular canal benign paroxysmal positional vertigo,posterior semicircular canal benign paroxysmal positional vertigo, posterior semicircular canal light cupula, Meniere's disease and inferior vestibular neuritis are reviewed.
下跳性眼球震颤并不罕见，通常被认为是一种中枢神经系统疾病。然而，有许多疾病仅表现为下跳性眼球震颤或眼球震颤中的下跳成分，包括外周和中枢前庭疾病以及Chiari畸形。本综述将简要总结前庭眼反射以及外周起源的下跳性眼球震颤的机制，然后对常见的前庭疾病如前半规管良性阵发性位置性眩晕、后半规管良性阵发性位置性眩晕、后半规管轻嵴帽、梅尼埃病和下前庭神经炎进行综述。
