Traumatic Optic Neuropathy
The optic nerve may be damaged by trauma to the head, orbit, or globe. Vision loss is usually immediate and severe with a relative afferent pupillary defect present. Initially, the optic nerve appears normal, but it becomes atrophic within 1–2 months of injury. Management is controversial and may include high-dose intravenous steroids and optic canal decompression.
