Complete evulsion of the optic nerve.
Evulsion of the optic nerve is an uncommon traumatic event, probably because the intraorbital portion of the optic nerve is mobile and surrounded by sheaths. The present paper reports a case of complete evulsion of the optic nerve with retinal detachment and discusses the possible patho mechanisms involved. Fluorescein angiography showed no retinal circulation.

A 17-year-old boy had an evulsion of globe and optic nerve from an automobile accident. Computed tomography showed a severed optic nerve on the injured side. A visual field defect was demonstrated in the other eye.
متن کاملPartial evulsion of optic nerve. Fluorescein angiographic study.
Evulsion of the optic nerve is a rare complication of trauma though well recorded in the Concurrent haemorrhage into the vitreous often delays diagnosis so that when ophthal-moscopy is possible the optic disc is masked by glial tissue extending into the vitreous. Persistence of these opacities may permit accurate diagnosis only after pathological examination (Lister, 1924). Spizziri (I964) phot...
متن کاملPaintball trauma and mechanisms of optic nerve injury: rotational avulsion and rebound evulsion.
PURPOSE Ballistic impact studies and supercomputer modeling were performed to elicit the mechanisms of optic nerve rupture that may accompany blunt ocular trauma. METHODS Paintball ocular impact responses were studied with abattoir-fresh porcine eyes. Physics-based numerical code CTH was used to produce robust geometric and constitutive models of the eye and orbit, providing a comparative 3-D...
متن کاملEffect of scuba-diving on optic nerve and sheath diameters
Background :There is not any data available about the effect of high bar pressure condition on intracranial pressure. In this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated. Methods : Twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. Only one perso...
