Abstract
-
Clinical signs of the optic nerve injury are characterized by absent or diminished light reaction of the pupil on the affected side, a wound in the lateral part of the eyebrow and bleeding from the nose. On X-ray studies, the optic canal fracture can be noticed occasionally. In this study, eleven cases of the optic nerve damage due to a blunt head trauma were studied for 6 to 30 months(average 9 months). Of these, the optic canal fracture was revealed in 5 cases. Among the 5 cases, three cases received surgical decompression of the optic canal through frontotemporal approach with visual improvement in 2 cases(66%). Eight cases were treated by medical therapy with visual improvement in 5 cases(63%). Visual recovery of the optic nerve injury with optic canal fracture(60%, 3/5) was similar to those with no optic canal fracture(66%, 4/6). On the bases of our study, the optic nerve damage should be treated by intensive medical treatment and if the optic canal fracture exists, early surgical intervention should be performed.
