What kind of trauma causes optic nerve damage?
The optic nerve is vulnerable to indirect and direct trauma causing functional impairment of vision. Optic nerve injuries occur in the setting of head injury which is often a consequence of road traffic accidents or falls.
Can you recover from traumatic optic neuropathy?
Outcome and Prognosis Patients with no light perception (NLP) likely have little to no recovery in vision. However, studies show that up to 50% of patients with traumatic optic neuropathy (TON) can have some improvement in vision, with or without treatment, although most of the time improvement is minimal.
Is traumatic optic neuropathy permanent?
Traumatic optic neuropathy (TON) is an uncommon but often devastating cause of permanent visual loss after blunt or penetrating injury.
Can optic neuritis be caused by trauma?
It is caused by a penetrating injury to the area of optic nerve. Indirect TON is caused by acceleration/deceleration forces due to the blunt head or closed globe trauma.
What are the symptoms of traumatic optic neuropathy?
Symptoms of Traumatic Optic Neuropathy
- Partial or complete vision loss.
- Blurred vision.
- Decreased color vision.
- Afferent pupillary defect (abnormal response by a pupil when exposed to light)
What would happen if the optic nerve was damaged?
