Optic Nerve

A variable degree of optic atrophy can become apparent a few weeks after a contusion injury. Blunt injuries to the eye can cause bleeding into the optic nerve sheath or tearing of the tiny pial blood vessels that supply the nerve, both resulting in complete, irreversible loss of vision on the affected side. Attempts have been made to relieve the situation by emergency decompression of the optic nerve, nerve sheath fenestra-tion, use of hyperbaric oxygen and highdose steroids. No treatment has shown a clear benefit except optic nerve decompression in specific circumstances.
