MS in the prodromol stage (before dx) is notoriously difficult to pin down. People who appear in a neuro's office with a lack of clinical symptoms (Babinski's, L'hermitte's, hyperreflexia, spastic responses in various muscles, visual problems, and so on), but do have suggestive lesions of the brain and/or spinal cord on MRI can be suspected of having one of several problems, including stroke. Doctors also like to to have some sort of clinical history (preferably a pattern of relapsing remitting symptoms) before dxing MS. There is no definitive empirical test for MS. Dx is generally made using MRI, evoked potentials, spinal tap, and clinical history. Even then, the dx can be called into question.

I'd take the blind query with a grain of salt. Vision problems and optic neuritis are common in MS, but actual blindness is comparitively rare, and then usually in the end stages. A fairly uninformed (being kind) and ignorant (being harsh) comment by this neuro, IMO.

It's hard to swallow your fear and be patient, I know. But you're going to have to be. And persistent. If lesions have shown up on your MRI, you need to find out what they are. A piece of unsolicited advice? If this neuro patronizes you again, either politely put him in his place or fire his *** and find another. Good luck. Though I'm glad to meet you I sincerely hope you don't have MS.
