I too had lesions on MRI scan and vision was not good and the opthamologist did all kinds of tests on my eyes
and could not find a thing wrong. It wasnt until I did IV abx my second round of IV abx my eyes were not painful
or sensitive to light after that. I still get fuzz like vision, and it feels like I have sleepies in my eyes. But found out
that I do have allergies that cause dryness and itching and sometime watery.
But the neuro said that my lesions were caused by Lyme disease. There are other things that a neuro can do to
determine MS without a spinal. If you are willing they are willing to take your insurance money.
Good Luck hope everything works out for you.
