Orbital Decompression for Treatment of Acute Visual Loss After Facial Trauma.

Injury to the orbital region represents a significant proportion of emergency department attendances and it is a common injury in patients with multisystem trauma. To date, trauma remains a leading cause of monocular blindness.Traumatic optic neuropathy may be caused by direct trauma to the optic nerve and from compression caused by foreign bodies and bone fragments. Indirect trauma can lead to visual loss from transmitted force to the optic canal by blunt facial trauma without associated fractures. Occasionally traumatic optic neuropathy is due to reversible changes, such as edema or contusion.High-dose intravenous steroids and surgical decompression of the optic canal have been advocated for the management of acute traumatic optic neuropathy, but the efficacy and safety of these treatments have been questioned.The authors present 3 patients with traumatic optic nerve injury, 1 due to a gunshot wound to the face and 2 caused by blunt facial trauma, where fragments of bone intrude into the orbit leading to compression of its content. These injuries where successfully treated with both preoperative intravenous steroids followed by acute surgical decompression of the orbit with return of visual function.
