Hello, my neurologist saw inflammation behind my eye and suspects ms ( due to other symptoms and my mri. i have no pain when moving my eyes so i dont know if it could be optic neuritis. what else related to ms could cause inflammation behind the eye?

Besides multiple sclerosis, optic nerve inflammation (optic neuritis) can occur with other conditions, including infections or immune diseases, such as lupus. Rarely, another disease called neuromyelitis optica causes inflammation of the optic nerve and spinal cord.

Dr Le points out some of the more likely causes, and indeed, several other disorders, besides MS, need consideration. A series of blood tests should be done, lumbar puncture may be of value. Spinal cord imaging is likely necessary.
