Thyroid-associated ophthalmopathy (TO) is the most common extra thyroid manifestation and the most important of autoimmune thyroid disease. The use of oral or intravenous steroids administration is one of the strategies for treating. This review evaluates the effect of intravenous steroid administration versus orally administered in the treatment of TO. Clinical trials were identified in the literature from January 1980 to November 2013. Studies were selected independently by the reviewers. We found four clinical trials comparing the use of intravenous versus oral steroid in the management of TO. All patients receiving steroid regardless of method of administration have improvement with respect to their condition before the start of treatment. Three studies show statistically significant differences in the improvement of the parameters evaluated in favor of receiving the steroid intravenously. Steroids are generally well tolerated, but adverse effects are more frequent in patients receiving oral therapy (p˂0,0001). Three of the studies used the same doses and schedule for administration of intravenous methylprednisolone. For oral administration each study presents a different scheme. We conclude that the evaluation of patients who receive steroids for the management of thyroid ophthalmopathy should be comprehensive and multidisciplinary. Those who have most benefit are those who present with moderate or severe classified as OT, and with a scale score of activity >4. TO patients receiving intravenous methylprednisolone therapy, compared to those treated with oral prednisone or methylprednisolone have a greater percentage of improvement in the TO, and this improvement was also observed earlier and with fewer adverse events.
