Oral steroids work pretty well for me, and they cost me about $5 (or a little more) at Walgreens when the doctor calls in a Rx for me.

IVSM is expensive and I have to go to the outpatient infusion center to get them. (I've tried to get them to Rx them for home use...my dad's a nurse and so is my aunt, but nope...no go on that yet)

Oral steroids are not good to have for vision related problems. Something about the oral steroids making you more susceptible to a re-occurance of another optic neuritis flare.

IVSM worked great on me the one time I had it for vision issues. (other time I had IVSM was because I was having a flare that was affecting my walking and it scared me. IVSM worked great that time too)
