Optic nerve avulsion, ultrasound and MRI findings

Abstract

Optic nerve avulsion is a rare but serious presentation of ocular trauma. It is characterized by disinsertion of the nerve fibers from the globe at?the level of the lamina cribrosa. It is usually associated with a decelerating injury of significant momentum and usually results in a severe and permanent visual loss.1,2 Here we report a patient with optic nerve avulsion secondary to a sporting injury and discuss the role of MRI and B- Scan ultra-sound.
