Abstract
Based on the role of oxidative stress in the pathogenesis of Graves’ hyperthyroidism
and Graves’ orbitopathy, the use of the antioxidant agent selenium has been proposed
and several studies on the subject have been conducted, both in vitro and in vivo.
Whereas a true benefit related to the use of selenium in patients with Graves’ hyperthyroidism
has been questioned, its use in patients with mild Graves’ orbitopathy is generally
believed to be beneficial because of which selenium has entered in the clinical practice
for this eye condition.
Key words
