My sister is detected with myasthenia gravis. She is having problem of double vision and put on steroids. Currently she is having severe pain in her left eye (same eye which is having problem of double vision). She was suggested for eye muscle exercise by one of the eye specialist but other eye specialist refused to assist in muscle exercise by machines because of myasthenia gravis. We don't know what to do. Can any of you please help in this case. Thanks.
