How I do it - endoscopic endonasal optic nerve decompression for traumatic optic nerve neuropathy.

Traumatic optic neuropathy (TON) consists of damage to the optic nerve following head injury and affects about 0.5–5% of patients with closed head injuries. It is characterized by a sudden decrease in visual acuity and/or visual field loss. Surgical treatment is usually warranted when ongoing compression occurs at the level of the optic canal. We describe the technical nuances of endoscopic endonasal approach for compressive TON and add evidence supporting this approach as a valid option to treat this condition. [ABSTRACT FROM AUTHOR]
