Traumatic avulsion of the eyeball: a case report

Ocular trauma is very common, but globe avulsion along with optic nerve avulsion is a rare clinical event. Blunt trauma during a road traffic accident can cause rupture or avulsion of the globe and the outcome can range from complete recovery on repositioning to visual loss because of globe perforation or optic nerve injury. Here, authors report a case of a 20-year-old male who presented with history of a road traffic accident causing severe facial injuries. The physical examination revealed oedema and ecchymoses over the right side of the face with avulsion of the right eyeball anteriorly outside the orbit along with avulsion of the optic nerve. The visual acuity in the injured eye was no perception of light and the direct pupillary response was absent. Computed tomography revealed fracture of the roof and lateral wall of the right orbit. As the eye was not salvageable, enucleation surgery was done. Insertion of an ocular prosthesis for rehabilitation was planned. The presentation, investigations, surgery and follow-ups are described.

Optic nerve avulsion associated with central retinal artery occlusion following rotational globe injury

Avulsion of the optic nerve head is a rare and severe complication of ocular blunt trauma. Herein, we describe a case of 16-year-old boy, who presented with a rare combination of optic nerve avulsion associated with central retinal artery occlusion, following blunt trauma with a leather ball. This report highlights the potential blinding complication following rotational injury.

A Case of Traumatically Ruptured Medial and Inferior Rectus Muscles with an Avulsed Optic Nerve

PURPOSE: To report the good surgical results of multiple ruptured rectus muscles with avulsion of the optic nerve. CASE SUMMARY: A 39-year-old male patient underwent surgical exploration after rupture of the inferior and medial rectus muscles and avulsion of the optic nerve. The disinserted muscles were attached at the primary insertion site, and a served optic nerve was not found. Six months after the injury, the patient had orthotropia in the primary position without ischemia of the anterior segment. CONCLUSIONS: In rare instances, blunt trauma can result in optic nerve avulsion with ruptured inferior and medial rectus muscles. Surgical treatment can result in a favorable outcome.

Functional and structural analysis of partial optic nerve avulsion due to blunt trauma: Case report.

Partial optic nerve avulsion (ONA) secondary to finger gouging is an uncommon but devastating injury. A 21-year-old man who had an acute vision loss after accidentally getting poked by himself in his right eye when he fell down during jogging is reported. The patient was diagnosed with partial ONA. Magnetic resonance imaging revealed intact optic nerve. Optical coherence tomography (OCT) revealed deep cavity at the inferior-temporal half of the optic disc. Retinal nerve fiber layer thickness was also thin at the inferior quadrant with circumpapillary OCT scan. Visual field test and electrophysiological tests showed functional abnormality compatible with optic nerve lesion. Diagnostic tools for anatomical and functional evaluation may reveal the course of this injury.
