目的 :探讨眼球运动障碍、眼球震颤对脑干病变定位的临床意义。方法 :对 39例经 CT、MRI证实为脑干病变的患者行眼球运动障碍、眼球震颤分析。结果 :眼球垂直注视麻痹、会聚麻痹对中脑病变有定位意义 ;核间性眼肌麻痹对中脑、脑桥病变有定位意义 ;眼球水平运动障碍对脑桥病变有定位意义 ;延髓病变无眼球运动障碍 ;眼球震颤可发生在脑干各种部位病变。结论 :眼球运动障碍对脑干病变定位有临床意义 ;眼球震颤尤其是垂直性、旋转性、摆动性震颤对诊断脑干病变有一定临床意义 ;MRI对脑干病变定位、定性有价值 ,CT对脑干病变诊断有局限性。
Objective: To investigate the clinical significance of oculomotor disorders and nystagmus in the localization of brainstem lesions. Methods: 39 cases of patients with brain stem lesions confirmed by CT and MRI underwent ocular movement disorders and nystagmus analysis. Results: Paralysis of eyeball vertical paralysis, paralysis of paralysis has the significance of the location of midbrain lesions; paralysis of intercostal ophthalmoplegia has the significance of location of midbrain and pontine lesions; ocular level dyskinesia has the significance of pontine lesions; bulbar lesions without ocular motility disorder Nystagmus can occur in various parts of the brain stem lesions. Conclusion: Oculomotor dysfunction has clinical significance in the localization of brainstem lesions. Nystagmus, especially verticality, rotation and swinging tremor have some clinical significance in the diagnosis of brainstem lesions. MRI is valuable for localization and qualitative diagnosis of brainstem lesions. CT Diagnosis of brainstem lesions have limitations.
