I was put on Keppera the first of December. Within two weeks my eyelid in my left eye started drooping and I started noticing double vision. I was seen by an Optometrist and tested out to have 3 Diopters of Vertical prism. When I returned to my neurologist and complained about my double vision and eye drooping he ran teat on me thinking I had Myasthenia gravis. The blood test came back negative. He said he still believed that I had MG and put me on an additional medication to treat MG. That was three weeks ago. The new medication is not helping or improving. I went to see a Ophthalmologist and My prism is now over 6 diopters. My doctor swears it could not be the Keppra and refuses to take me off of it.. I really feel it is the Keppera. Just a feeling Any advise?
