Traumatic optic neuropathy with concealed CRAO following blunt trauma in a young male patient: A rare case report

Traumatic Optic Neuropathy (TON) is a condition which results from vulnerable nature of the optic nerve to direct and indirect trauma leading to functional impairment of vision. Several varieties of direct optic nerve injury may be identified: optic nerve avulsion, transection, optic nerve sheath haemorrhage, orbital haemorrhage, and orbital emphysema. Central retinal artery occlusion (CRAO) is the sudden blockage of the central retinal artery, resulting in retinal hypoperfusion, leading to rapidly progressive cellular damage, and vision loss. An embolism is the most common cause of CRAO. The degree of collateralization and the duration of retinal ischemia determines the retinal survival. There are only few reported cases of central retinal artery occlusion caused by blunt traumaWe report a case of traumatic optic neuropathy presenting along with central retinal artery occlusion following a high speed blunt trauma to eye in an otherwise healthy young male.
