Myasthenia gravis is a disorder of the connection between the nerve and the muscle. Typical symptoms include double vision (not just blurry vision), difficulty chewing, difficulty swallowing, difficulty breathing, ptosis (droopy eyelids), weak arms and legs. Symptoms are intermittent, waxing and waning. Fatiguing of muscles is a hallmark of the disease. Fixed double vision, that is always the same (meaning not fluctuating and usually with one specific direction), would make me concerned not for myasthenia, but more for another process, such as an oculomotor nerve palsy or another structural lesion. There are many things that can cause fixed constant diplopia; MS is one of these, but that diagnosis must be made in the appropriate context. The MRI of your brain sounds like a good idea.
