The effect of head tilt on postrotatory nystagmus was studied in patients at long time follow-up of complete unilateral vestibular lesions. Ten patients were tested 2-4 years after unilateral vestibular neurectomy. They were all found to have short VOR time constants. However, at postrotatory head tilt the VOR time constant was further shortened. This suggests that the velocity storage mechanisms may function even in cases with complete unilateral vestibular lesions.
在完全性单侧前庭病变的长期随访患者中,研究了头部倾斜对旋转后眼震的影响。对10例患者在单侧前庭神经切除术后2 - 4年进行了测试。发现他们均有较短的前庭眼反射(VOR)时间常数。然而,在旋转后头部倾斜时,VOR时间常数进一步缩短。这表明即使在完全性单侧前庭病变的情况下,速度存储机制仍可能发挥作用。
