Visual Evoked Potentials
A visual evoked potential (VEP) test evaluates the visual pathways in your brain.
During the test, you watch a video monitor with a moving pattern.
Watching the moving pattern produces electrical activity in your brain that is measured by several electrodes attached to your head.
It is used if you are experiencing:
- double vision
- blurred vision
- loss of part or all of your vision
- eye injuries
- head injuries, or
- weakness of eyes, arms, or legs
