Optic nerve injury

Visual loss due to optic nerve injury after closed traumatic brain injury constitutes a formidable diagnostic and therapeutic challenge for the clinician. Assessment must be made of the site of optic nerve injury, and this is often difficult in the patient with an altered level of consciousness. A decision regarding optic nerve decompression must be formulated, yet the literature is confusing with regard to operative indications.

If conscious: serial quantification of vision in each eye is important 1).


Care must be taken to avoid optic nerve injury caused by the retraction and/or the heat of the drill when doing ophthalmic artery aneurysm surgery 2).
