I used to believe I had answers, but then I got MS! It attacks our nerves and bodies in so many different ways and degrees that it is hard to have any concrete guidleines as to what is "normal" for MS patients or not. I am starting to believe that the best answer is simply "what effects you is what effects you". Confused? Me too!!
I am currently having a second bout of optic neuritis. My first was three years ago when I was diagnosed with MS due to right eye problems. This time, my left eye is having the difficulty. I just finished IV steroids and am now taking oral prednisone. My vision is improving, but I would swear my right eye is starting to be affected as well, only to a much lesser degree. Cripes.
So back to the clinician in me: yes, ON can occur in both eyes simultaneously, but it is more common in only one at a time. Any damage to the optic nerve will affect vision, be it peripheral or central/reading vision. Back to HarryZ's question, optic nerve damage has likely resulted from bouts of ON in the past. If you have ON attacks, a certain amount of permanent damage is done even in remitting/relapsing MS when the function comes back. I should think it is safe to assume that this continual damage may have caught up with your wifes vision, and even though she has no active inflammation currently, she does have some permanent damage. I like Loobie's optic cable analogy, and with apologies to Loobie, I will probably steal that and us it with patients
