反跳式眼颤是指长时间向一侧凝视后再注视前方时出现的眼颤类型,其快相与偏心性凝视的方向相反。以往研究提示这种眼颤是中枢神经系统如小脑在试图保持偏心性凝视时产生的短暂倾向,但确切的起源仍未肯定。本研究通过对存在反跳式眼颤的患者行磁共振(MRI)检查,进一步阐明其起源 Rebound nystagmus refers to the type of nystagmus that appears when gazing at one side for a long time and then looking forward. The fast phase and the eccentric gaze are opposite in direction. Previous studies have suggested that this nystagmus is a transient tendency in the central nervous system, such as the cerebellum, to attempt to maintain eccentric gaze, but the precise origin remains uncertain. In this study, magnetic resonance imaging (MRI) was performed in patients with retrograde nystagmus to further elucidate their origin
