摘　　要：单侧前庭功能丧失后的扭转视动性眼球震颤的非对称功能及代偿作用 本研究目的在于分析17例梅尼埃病患者接受治疗性单侧前庭神经切断术（UVN），术前及术后1周、1个月和3个月的扭转视动性眼球震颤（tOKN）情况。当沿着视线进行的视动刺激以各种恒角速度向病变侧或健康侧运动时，研究tOKN。使用可视眼震电图分析仪分析tOKN的动态特性及静态眼球旋转。Torsional optokinetic nystagmus after unilateral vestibular loss： Asymmetry and compensation The aim of this study was to analyse torsional optokinetic nystagmus （tOKN） in 17 patients with Meniere＇s disease before and after （1 week, 1 month and 3 months）-a curative unilateral vestibular neurotomy （UVN）. The tOKN was investigated during optokinetic stimulations around the line of sight directed towards either the lesioned or the healthy side, at various constant angular velocities. Dynamic properties of tOKN and static ocular cyclotorsion were analysed using videonystagmography.
