Abstract

Traumatic optic nerve avulsion is a rare event. A case of complete unilateral optic nerve avulsion after blunt ocular trauma without major damage to other ocular structures is reported. Bscan ultrasonography with 10 and 20 MHz probes proved to be helpful in diagnosing the optic nerve lesion, whereas orbital computed tomography was inconclusive. The prognosis is ominous and it is dependent on the initial visual acuity, which was no light perception in this case. There is no efficient treatment for complete optic nerve avulsion, and no specific treatment was performed in this case.
