What are normal limits in a VER test

[figuerpa]

Does anyone know what the normal limits in a VER test are? I have been googling forever and can't find the answer.

Thank you

I don't know what the implications are if the time lapse is less than 100 milliseconds. My guess is that this would be a good thing. It certainly doesn't indicate a problem with the optic nerve.

Probably, natural variance allows for the same deviation backwards as forwards in healthy individuals. It seems impossible that nerve conduction speed could exceed a certain threshold, at any rate.

The problem for ON/MS purposes is slowness, not speed. If your level was 96.9, that sounds perfectly healthy.

Thanks Wobbly,

I am confused. Mine was 96.9 so I am guessing that is normal?

Thanks Ess,

I will check the site you mentioned. How low can the number be before it is abnormal in that sense?

Thank you

Please see http://www.mult-sclerosis.org/VisuallyEvokedResponse.html

The 'normal' response time is 100 milliseconds, though a certain amount of deviation from this standard is also considered normal. Therefore, up to 115 milliseconds falls into the normal range. At 115 or more, the test result is abnormal.

Hope this helps.

is this like a VEP test for vision?  if so, maybe check that one??  
good luck
