here is a website that describes what the VER is (it's also called a VEP):
It seems to me -- but I am NOT a doctor, and NOT familiar with this test -- that if there was a difference in perception between your eyes, it would be noted by your doctor. He'd have to explain to you what the difference is, and what relevance it might have to a diagnosis.
The test is designed just for that reason --to discern if there is a difference in transmission of signals between the brain and each eye...but I don't know if what you experienced demonstrates that or not.
...I am not a doctor, nor health professional, and don't pretend to be one, here.....
