视抑制试验的临床应用研究

Clinical Application of the Visual Suppression Test

对２００例诊断明确的几种周边和中枢前庭疾病患者，在进行冷水试验的同时测试了视抑制功能，用眼震电图仪记录，计算ＶＳ值。１６２例周围性前庭损害者ＶＳ均正常，３８例中枢前庭损害者中２７例ＶＳ异常，占７１％。讨论了各种定量测试固视机能方法的优缺点，并就各种眩晕疾患的视抑制试验结果进行分析，探讨其临床意义。

cases of peripheral and central vestibular disorder patients were examined by col-oric test and visual suppression test (VS)simultaneously.The results with ENG recording showed:(Ⅰ)VS score >50%indicates normal function。(2)VS score 50%～10%is function decreased.(3)V5score < 1 0%shows function failure。(4) Patients with negative VS score accompanies nystagmus strengthen with eye open when in the light also,the clinical application of the VS test for diagnosis of several kinds of vestibular disorder were discussed。
