Optic nerve trauma with prolonged blindness followed by visual-evoked potential
Summary
A radio antenna injury caused immediate blindness but preserved optic nerve electrical activity, detected by visual-evoked potentials (VEP). VEP changes predicted eventual visual recovery, highlighting its diagnostic value in optic nerve trauma.
Area of Science:
- Ophthalmology
- Neuroscience
- Trauma Medicine
Background:
- Optic nerve damage from penetrating orbital trauma can cause severe vision loss.
- Initial clinical and imaging findings may not fully predict visual outcome.
