摘要

視神經管症候群(optic canal syndrome)是指任何足以引起視神經管內容物（如視神經、眼動脈、及交感神經纖維等）損傷的病灶所造成的病症。致病原因主要為腫瘤，炎症，及外傷等。臨床上除了外傷性視神經病變造成的視神經管症候群比較常見外，其餘均不常見，而且很少被單獨提出討論。臨床症狀主要為快速、無痛之視力減退。眼部檢查除了明顯的瞳孔傳入障礙(relative afferent pupillary defect, RAPD)之外，多無異常發現。容易與視神經炎、眼窩尖端症候群、及上眶裂症候群等混淆。電腦斷層及核磁共振是最佳診斷工具。此病病程進展迅速且視力預後不佳，臨床醫師宜提高警覺，避免延誤診斷及治療之時機。

Optic canal .syndrome is disorders that damage the intracanalicular contents in the optic canal, including the optic nerve, ophthalmic artery, and sympathetic plexus. Space occupying lesions, inflammation, and trauma are common causes. It is rarely seen clinically and is seldom discussed except trauma. The most important clinical manifestation is painless, rapidly progressive visual deterioration. There is often no major abnormal ophthalmic finding except the obvious relative afferent pupillary defect (RAPD). It has to be differentiated with optic neuritis, orbital apex syndrome, and superior orbital syndrome. The best diagnostic tools are computed tomography and magnetic resonance image. Early diagnosis and treatment is very important because of the rapidly progressive clinical course and poor prognosis.
