摘要

報告一例兩側內縱束(Medial longitudinal fasciculus, MLF)症候群之病例。檢查其眼球運動，以電氣眼震圖詳細記錄兩眼運動之情況，發現兩眼向內側轉動時會受到限制，但內聚力(Convergence)良好，顯示兩側內縱束約有病變，但無合併垂直運動之限制。電氣眼震圖檢查發現兩眼異常眼球運動，在基本上為快速眼球運動之異常，主要變化為兩側Slow saccade。導致兩側內縱束症候群的病變，在國外以脫髓鞘疾病最多，本病例乃因腦血管疾病所致，特提出報告。

A case of 57 year-old male patient with bilateral medial longitudinal syndrome was reported. The major problem of extraocular movement was impaired adduction of both eyes but with intact convergence. There was no limitation of vertical eye movement. Electronystagmographic examination of eye movement revealed the main abnormalities were appearance of slow saccade during saccadic eye movement and slowing of quick phase at optolinetic nystagmus test. The most common cause of bilateral internuclear ophthalmoplegia in western countries is multiple sclerosis. The case we reported here was caused by cerebrovascular disease.
