前庭性眼震(VN)是前庭分析器功能最早期和微细变化的反应,是前庭系疾病鉴别诊断的重要依据,但至今尚无公认的病因分类法。作者根据临床经验提出了按病因学特点分类,这种分类法方便,有利于确定前庭分析器敏感性及其不对称的特征和程度,前庭功能障碍的代偿程度以及前庭障碍的机制和治疗效果。共分三类: Ⅰ.自发性眼震:无前庭和眼的外来刺激,在完全安静生理条件下发生的眼震。Ⅱ.诱发性眼震:在平衡器受到阈值或近阈值强度的刺激或因大脑血液动力学变化而发生。
Vestibular nystagmus (VN) is the earliest and subtle changes of vestibular analyzer. It is an important basis for the differential diagnosis of vestibular diseases. However, there is no recognized classification of etiology. According to the clinical experience, the author puts forward the classification according to etiological characteristics, which is convenient for classification and is helpful for determining the sensitivity and asymmetry characteristics and degree of vestibular analyzer, the compensatory degree of vestibular dysfunction and the mechanism and therapeutic effect of vestibular disorder . Divided into three categories: I. spontaneous nystagmus: no vestibular and eye external stimuli, nike air max, in completely quiet physiological conditions occurred nystagmus. Induced nystagmus: Occurs when the balancer is stimulated by a threshold or near-threshold intensity or due to cerebral hemodynamic changes.
