Hello all Today I had my 6 month Neuro appt. Had ON last March/April, have had a blind spot in same eye since November, saw consultant then and again today and he’s sending me for visual electrophysiology. I’ve found a little of what this is, but not entirely sure what it may find, wonder if anyone has any ideas? I know I should have asked but I didn’t in time. Many thanks, Sam

Sounds like visual evoked potentials. To test how you optic nerve is transmitting the signals from your eye.
