作者检查了207例具有不同性质的周围性及中枢性前庭系统疾病患者。让患者头部向后倾斜60°作旋转试验,旋转骤停后可见到两种类型的眼球震颤:旋转性眼震及相反方向之水平性眼震。通常水平型较旋转型存在时间长,在眼震行将结束时其反应一如对侧之水平性眼震。当患者具有优势偏向或自发性眼震时,水平性眼震更为明显,存在时间更长。符合以上规律的占90％左右。
The authors examined 207 patients with different types of peripheral and central vestibular diseases. With the patient’s head tilted 60 ° to the back for a rotation test, two types of nystagmus were visible after a spin-down: rotational nystagmus and horizontal nystagmus in the opposite direction. Usually horizontal than the rotating type of existence for a long time, at the end of nystagmus response as the contralateral horizontal nystagmus. When patients have predominantly biased or spontaneous nystagmus, horizontal nystagmus is more pronounced and exists longer. Meet the above rules accounted for about 90%.
