Pathomechanism of Optic Nerve Avulsion

Medical Hypotheses, 2019
Optic nerve avulsion following peri-orbital trauma is an enigmatic clinical entity. Several mechanisms and ideas have been put forward to derive a logical conclusion, however, each factor independently does not appear to explain the mechanism in a logical way, therefore, here we elaborate the probable chain of events responsible for this complication ...

Ultrasonography in Optic Nerve Head Avulsion

Acta Ophthalmologica, 1991
Abstract The diagnosis of post traumatic optic nerve avulsion is often obscured by the presence of concomitant vitreous haemorrhage. Electrodiagnostic tests, CT scan and fluorescein angiography have not proved helpful in substantiating the diagnosis of this entity in the early stages.

Optical Coherence Tomography in Optic Nerve Head Avulsion

Orbit, 2012
Early diagnosis of optic nerve head (ONH) avulsion may be difficult due to an obscured fundus view. Although B-scan ultrasonography is more useful than MRI and CT imaging, it has limited sensitivity and specificity. Optical coherence tomography (OCT) can be used to identify optic nerve pathology.

Traumatic Optic Nerve Avulsion: A Case Report

Journal Francais D'Ophtalmologie, 2012
Case report of a traumatic optic nerve avulsion.We report the case of a traumatic right optic nerve avulsion in an 11-year-old boy as a result of a contusion with a surfboard. On initial examination, the patient exhibited bilateral mydriasis with a right afferent pupillary defect. Visual acuity was no light perception. A moderate microhyphema was noted

Traumatic Avulsion of the Optic Nerve

Optometry and Vision Science, 1992
ABSTRACT Avulsion of the optic nerve is an infrequent traumatic event which results in a permanent and usually devastating loss of vision. We present two cases which highlight the salient features of partial and complete optic nerve avulsion.
