关于核间性眼肌麻痹的临床表现,过去报导的着重点有二:(1)患侧内直肌向对侧水平注视的作用不足,(2)外展眼的眼球震颤。作者根据临床观察发现二个新的征状:(1)视觉动力性眼球震颤,(2)眼辨距不良。视觉动力性现象:当患者注视旋转鼓上的长条时,即发生分离的眼球震颤,一眼的震幅明显地较另一眼大,当目标向患侧移动时,对侧眼的震幅较大,患者如为右后核间眼肌麻痹,向右注视时双眼正常,向左注视时则右眼内直肌落后,左眼有外展性眼球震颤,旋转的目标自患者左侧向右移动,可见左眼反应的震幅较大。当双侧核间性麻痹时,目标自患者左侧向右移动,则左眼眼球震颤著明,自右侧向左移动,则右眼眼球震颤著明。
The clinical manifestations of intraocular ophthalmoplegia have been reported in the past to be focused on two aspects: (1) the insufficient effect of the medial rectus muscle on the opposite side of the eye, and (2) nystagmus in the abducted eye. The authors found two new symptoms based on clinical observations: (1) visual motility nystagmus, (2) poor eye pitch. Visual dynamic phenomenon: When the patient gazed on the long strip on the rotating drum, a separate nystagmus occurred. One eye’s amplitude was obviously larger than the other. When the target moved to the affected side, the amplitude of the contralateral eye was larger , The patient was paralyzed by the ophthalmoplegia in the right posterior nucleus, the eyes were normal when looking to the right, the rectus muscle in the right eye was backward when the patient was looking to the left, and the patient had an extensional nystagmus in the left eye. The target of rotation was shifted to the right from the left of the patient , Showing a larger amplitude of the left eye response. When the bilateral nuclear paralysis, the target from the left to the right patient movement, the left eye tremor Ming, from the right to the left, then the right eye nystagmus Ming.
