Brief Summary

Autoimmune ophthalmopathy is clinically evident in one third of Graves' disease cases. In most cases it is mild; however, in 3 to 5% of cases it has a severe presentation. At present, the treatment is directed to identify vision threatening which requires aggressive intervention, usually with glucocorticoids. For mild cases the treatment is limited to the normalization of hyperthyroidism and support measures. Preliminary data show that pentoxifylline and bromocriptine may have a favorable effect in the course of ophthalmopathy by inhibition of the synthesis of TNF-α, VEGF, glycosaminoglycan production, and lymphocyte infiltration. Therefore, the aims of this study were to evaluate the effect of bromocriptine and pentoxifylline on the clinical course and quality of life of patients with mild to moderate ophthalmopathy associated to Graves´disease. Methods. Patients with mild to moderate ophthalmopathy, with less than one year of evolution, and naive to treatment were randomized to receive treatment during 12 months with either 1) bromocriptine (5 mg twice a day) + methimazole (30 mg/day), 2) pentoxifylline (400 mg twice a day) + methimazole (30 mg/day), or 3) methimazole only (30 mg/day). They completed 10 visits to evaluate proptosis and clinical activity score (CAS). In addition, in the first and last visit the quality of life questionnaire specific for Graves' ophthalmopathy(GO-QOL) was applied.
