[Catie,

Mine is purely Ocular and all my tests came back negative for MG, including blood work except for the Single Fiber EMG. They stick a needle in the muscles around the eye and you are hooked up to some machine where they can tell whether or not messages are getting through from the brain to the eye. I had already had an EEG, which showed the brain working normally. I had already had my eyes examined and the results were my eyes were healthy. So, what was causing the double vision? An MRI discounted many diseases. The SFEMG showed a weak case of it. Of course, like the dr. said, he could do the test on any given day and it could show mild to severe depending on the symtoms that day. Hope this helps. I too at times think I am imagining my legs and arms being weaker. In fact, I am going to MUSC in a couple of weeks to have the SFEMG repeated and this time in the arm as well. Take care! Kathie Glenn
