Mary is absolutely correct when she comments that oral steroids are NOT recommended
for the treatment of a relapse of
Optic Neuritis. A long study, (about 15 years) called the
Optic Neuritis Treatment Trial, found that use of oral steroids appeared to put the patient at risk for more episodes of ON. Neither IV steroids, oral steroids nor no treatment at all had any effect on the ultimate outcome - loss of vision, so the treatment is for symptomatic use only.
