不同眼动特征在中枢性孤立性眩晕中的诊断价值

目前研究认为,孤立性眩晕是后循环TIA或脑梗死的常见表现形式,而且当中枢病变患者以前庭症状发病时,初始的临床表现中,孤立性眩晕较非孤立性眩晕更为常见.长期以来,临床医师对中枢性眩晕的诊断多基于临床体征的定位诊断,事实上,在脑干和小脑中包含诸多调控眼动的中枢前庭结构,这些结构受损会导致相应的异常眼动模式.本文综述了中枢性...

Diagnostic Value of Different Eye Movement Characteristics in Central Isolated Vertigo

Isolated vertigo is a common presentation in posterior circulation TIA and stroke.Of the vestibular symptoms of initial presentation,isolated vertigo is much more often than nonisolated vertigo.For a long time,the diagnosis of central vertigo was made mostly based on routine clinical positioning.In fact,the brain stem and cerebellum contain many central vestibular structures that regulate eye movement,and the damage of which can lead to eye movement impairment.This article reviewed the clinical manifestation and different eye movement characteristics of central isolated vertigo,and 6 central vestibular structures(vestibular nuclei,nucleus pre-positus hypoglossi,inferior cerebellar peduncle,nodulus,tonsillar and floccular),aiming at promoting clinical understanding and differential diagnosis for central isolated vertigo.
