After 15 years+ with MS, I have just had my first attack of optic neuritis even though I progressed into SPMS 6 years ago. I guess my O.N. was comparatively mild as O.N. goes. I have always thought that the usual treatment was intravenous steroids for 3 days. My primary neuro doc told me, as did the 2 neuro opthamologists that he sent me to, that unless the attack is really bad, as in loss or partial loss of eye sight, then they usually let it resolve itself. That is what I did and it did resolve itself. However, it must resolve within two weeks or intravenous steroids are then used. Also, I read that oral steroid treatment is not recommended and probably does not in any help with O.N.. My neuro docs are associated with the MS Research Clinic which is in turn a part of Dalhousie University Medical School here in Halifax, Nova Scotia, Can. These docs are very knowledgable and very compassionate people. Is this the standard practice in the U.S.? I have checked with other MS clinics throughout Canada, and it seems to be prevalent practice in many parts of this country. I would love to hear your thoughts and/or experiences on O.N. treatment. Thanks all. Look forward to hearing from you.
