本文分析了28名正常人、10例前庭末梢病变和31例颅内病变患者视动性眼震(OKN)及视跟踪试验(ETT)的结果。颅内病变组诱发OKN角速比正常为低,甚至缺失,其左右差异大多在28％以上,并有节律不齐;前庭末梢病变组与正常人相似,正常和前庭末梢病变组的ETT曲线有89.5％为Ⅰ、Ⅱ型;颅内病变组有80.6％为Ⅱ、Ⅳ型。10例Ⅳ型全部为颅内病变。OKN与ETT是鉴别中枢与末梢病变的有效试验,是检查平衡功能值得推荐的方法。 This article analyzes the results of visual acuity (OKN) and visual follow-up test (ETT) in 28 normal subjects, 10 cases of vestibular peripheral lesions and 31 cases of intracranial lesions. In the intracranial lesions group, the OKN-induced angular rate of OKN was low or even missing, with the difference of more than 28% between the two groups. The ETT curve of the normal and the vestibular lesions was similar to that of the normal 89.5% were type I and type II; 80.6% of the group with intracranial lesions were type II and type IV. All 10 cases of type Ⅳ were intracranial lesions. OKN and ETT is an effective test to identify the central and peripheral lesions, it is recommended to check the balance function.
