Nice to meet you and I'm happy that you decided to post after reading for a while. What you are describing, if it's MS related, could be something called optic neuritis. It's typically something that an opthamologist would find whether you are having problems or not, but if it's something that is very recent it could be possible for it not to show up and the eye to appear normal. You could ask your doctors about that possibility, see what they say.
We do have quite a few people here with ON and I'm sure you'll be hearing from some of them soon. Welcome to the forum, and please feel free to share, vent, or ask any questions you might have. We'll do our best to help. Take care and I hope it's something that resolves quickly for you.
