| Abstract |
|
Optic nerve evulsion is a visually devastating and rare manifestation resulting in sudden visual loss after ocular trauma. The several hypothesis of mechanism include penetrating orbital injury causing a backward pull on the optic nerve, extreme rotation and forward displacement of the globe, and sudden increase in intraocular pressure causing rupture of the lamina cribrosa. The authors report a case of optic nerve evulsion in a 25- year old man who was struck in the right eye with a umbrella. The diagnosis was made by fundoscopic findings, fluorescein angiography, visual evoked potential, electroretinography, orbit computed tomography and magnetic resonance image. |
