[Thyroid orbitopathy, an overview with special attention to the role of radiotherapy]

Abstract

Thyroid orbitopathy is the most prevalent non-thyroid symptom in Graves' syndrome. It has a high incidence and particularly affects young women. Smoking is clearly involved in its development and progress, and in its response to different treatments. This autoimmune condition usually has a benign course, independent from hyperthyroidism, but its severe, progressive forms represent a major therapeutic challenge. Clinical evaluation poses great difficulties, as there is no truly objective rating scale representing disease activity. New molecular or inflammation markers may prove to be useful in this regard. This review reports new findings about its pathophysiology and the different techniques used for treatment over time. Discussion particularly focuses on the immunomodulatory role of radiotherapy, as well as on its role together with corticosteroids.
