This study is aimed to investigate the effect of hydroxychloroquine in patients with mild Graves' orbitopathy (GO).

Inclusion: Mild GO according European Group on Graves' orbitopathy (EUGOGO) guidelines diagnosed by endocrinologist and ophthalmologist; No previous treatment of GO except for eyedrops; Euthyroidism (normalized free T4 and TSH) for at least 2 months.
