Had these today. Am curious especially about the Visual Evoked Potentials test. I experienced the test very differently with each eye: with the right eye, the moving black and white checkerboard pattern on the second test run soon began to grey out, losing almost all contrast so that it was all more or less grey; In addition it became very difficult to spot the yellow centre square which also faded at the edges. With my left eye, these things did not happen at all and the moving checkerboard remained at constant contrast and sharpness. I still dont know if the fading was 'real' or meant to happen or if it was just my perception, as the tester evaded answering my query mid test.
Also on the leg test, my little left toe would not start to twitch until the dial was turned up to a high level and I couldnt feel the pulse unless it was somewhat higher than for the other leg. Anyone know how these tests work, particularly the visual one and what these things signify if anything?
Sorry if this appears multiple times, it is not posting normally for some reason which is driving me nuts.
