So, Abby, did you video tape yourself?? I cannot see my eyes doing this -- but, it MIGHT be happening. I remember in the "early days"....................one of the neuros (professor) was showing a resident "something". He had me look up for a couple of minutes -- my eyes got VERY tired. And then, he said, "See! That is a SIGN of MG!" I never knew what he meant. This was the same guy who did a teaching lesson to the resident about double vision. I was having left-sided double vision and the resident was dubious. My eyes looked FINE to him. So the professor turned off all of the lights in the examination room and turned on a pin light. He told the resident to look at the place the pinlight HIT my eyes in respect to my iris. On one eye, it was directly ON the iris -- on the other eye, it was off to the side of the iris. So the resident could then SEE that I was INDEED having DV. Wonderful professor. I've had some good docs!
