Not so new. Been around awhile. Dr. Calibresi (Head of Johns Hopkins MS Center) has been working with it for years. He DXed me in 02 at UMM. A neurologist at JH scanned me but seems PPMSers are not good for this technology. He moved away. My current neurologist at JH is involved in ON and eye scanners, but not the technology for me. Good doctors, but nothing they can do for me. Went to a neurological ophthalmologist way back when looking for answers. He said "I can't cure you, but I can do magic tricks for you" and he did.
