Hello! I have been having problems with double vision since February 2013, with a suspected, but as yet unconfirmed diagnosis of MG. Bloodwork panel for MG came back negative, so my neurologist is now sending me to a neuro ophthalmologist for 4 hours of testing...! I have been getting told a lot of things by people about what exactly is involved in the testing, such as inserting needles into the eyes or surrounding muscles, etc, and am getting more nervous about it as time goes on. Can anyone here please tell me what the testing really entails? Thanks!
