I get a lot of the visual type disturbances you mentioned, especially the shimmering. I have found that they are not as bad as long as my head is level and I am looking straight ahead. If I tilt my head or look to the side, things go wonky. I have a lot of double vision as well. I always attributed all the vision issues to the MG. The mestinon does improve the vision for a while and letting my eyes rest. Ice packs also help a lot. The pregnisone has not improved my eye symptoms.

I hope you find some answers. I had a very good experience with the neuro-optomologist. I am still pursuing more serious generalized weakness due to MG. Most days, my vision is the least of my troubles. They did note an enlarged optic nerve on my more troublesome eye.
