title: Delayed recovery from indirect optic nerve injury. A report of two unusual cases.
abstract: Two patients with indirect optic nerve injury are reported. In one, head injury was minor, while in the second, the head injury was severe. Both the patients had immediate type of optic nerve injury with complete visual loss. CT scans for the orbit and optic canal were normal. Visual evoked potentials (VEP) repeatedly performed in the first 6-8 weeks were absent in both the patients. Onset of visual recovery was very late, in first case it was noticed after 12 weeks and in the second case visual recovery started after 8 weeks. Both the patients had partial visual recovery.
