Ocular treatment of thyroid eye disease

Abstract

Thyroid eye disease is an autoimmune disease affecting ocular and orbital tissues. The inflammation may or may not parallel systemic thyroid conditions such as Graves disease. Disease manifestations result from tissue remodeling within the orbit. The abnormal stimulation of immune cells and orbital fibroblasts is probably involved. Our current understanding of the pathophysiology of the disease is limited and few rational therapies have been designed that target the underlying disease process. Treatment strategies vary depending on disease severity and activity. Recent small-scale studies have shown some promise with B-cell-depleting drugs such as rituximab, but this therapy requires further evaluation. The testing of new treatments is hindered by the lack of a reliable animal model of thyroid eye disease. © 2010 Expert Reviews Ltd.
