Computerized tomography (CT) demonstrated the precise anatomical relationship of the mucocele to the optic nerve inside the optic canal. It is proposed to use the term \u201coptic canal syndrome\u201d for patients with such clinical and CT presentation. Combined transcranial excision and transnasal drainage resulted in dramatic recovery of vision.<\/jats:p>","DOI":"10.3171\/jns.1986.65.6.0871","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T16:17:54Z","timestamp":1241799474000},"page":"871-873","source":"Crossref","is-referenced-by-count":12,"title":["Optic canal syndrome due to posterior ethmoid sinus mucocele"],"prefix":"10.3171","volume":"65","author":[{"given":"Chung P.","family":"Yue","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirpal S.","family":"Mann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fu L.","family":"Chan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"101","DOI":"10.1016\/0090-3019(86)90126-6","article-title":"Mucocele of the sphenoid sinus with the apex orbitae syndrome.","volume":"25","author":"Chen","year":"1986"},{"key":"b2","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"284","DOI":"10.3171\/jns.1978.48.2.0284","article-title":"Mucoceles with intracranial and extracranial extensions.
