Transantral-ethmoidal decompression of optic canal fracture.

A case of indirect trauma to the optic nerve was successfully treated with transethmoidal decompression. The literature was reviewed, and reports of poor results from neurosurgical procedures are cited. Improved results from transethmoidal decompression of the optic nerve have been reported by Japanese authors but, in our opinion, without proper selection of cases. Early diagnosis of traumatic compression of the intracanalicular optic nerve as evidenced by delayed and/or progressive vision loss following injury, coupled with prompt transantral-ethmoidal surgical decompression, should yield gratifying results in the treatment of this uncommon condition.
