It has everything to do with
your vision, however - if you have white spots, black spots or flaring colored spots in
your eyes, that indicates damage to the optic nerve. I have damage both to the optic nerve and to the retinal nerve fiber layer.
I certainly don't want to rain on your parade. I personally had changes to my face as a result of muscle weakness. My mouth on the right side sagged, as well as the right eyelid. The weakness didn't cause bagginess, however.
