眩晕病人长时程眼球运动观测的临床应用

Clinical Application of Observations of Iong-Term Lystagmus in Patients with Vertigo

本文对155例眩晕患者进行了长时程(30～60分钟)眼球运动观测。观测结果记录到异常眼动占58.1％。中枢神经系统疾病诱发的眩晕,以垂直性眼震为特点;而外周性或中枢性疾患引起的眩晕都可发生旋转性眼震。这些异常眼震可伴随症状的缓解而消失。因此这种方法可作为客观评价眩晕患者前庭功能状况的手段,有进一步研究的价值。

Long-Term (30～60 min)eye movements in 155 Patients with vertigo were observed in the prevent study. Result showed that vertigo caused by diseases of the central nervous system was characterized by vertical nystagmus. Both central and peripheral disorders might bring about rotatory nystagmus. Abnormal nystagmus was registered in 58.1% of the 155 patients. In these patients, the abnormal nystagmus might disappear along with the amelioration of the synptoms. This method provided an objective way of evaluating the vestibular function of the patients with vertigo. Therefore, further research would be of significance.
