Extra-ocular muscle haematoma masquerading uveal prolapse post blunt trauma to the eye: A case report.

Abstract

This is a unique case of a 75-year-old lady who presented to eye emergency department with blunt trauma to the right orbit three days after a fall. Examination under anaesthesia revealed right globe subluxation, corneal ulceration with hypopyon, avulsion of extraocular muscles and a supero-lateral uveal prolapse. The eyeball was enucleated and sent for histopathology which revealed an intact globe with an avulsed lateral rectus muscle hematoma which was clinically masquerading as uvea, and displacement of the optic disc and pre-laminar optic nerve, causing extensive injury of optic nerve axons at the level of the lamina cribrosa, as shown by the accumulation of β-amyloid precursor protein (β-APP).The case highlights the importance of awareness of uncommon presentations and masquerades during the examination and management of ocular trauma.
