Gravesʼ Orbitopathy: Current Concepts for Medical Treatment

Abstract

Background The therapy of severe manifestations of Gravesʼ orbitopathy (GO) is still a challenge and requires good interdisciplinary cooperation. It is especially important to use stage-adapted anti-inflammatory therapy to avoid irreversible damage.

Material and Methods Discussion of the latest results of multicentre randomised therapy studies on anti-inflammatory treatments for Gravesʼ orbitopathy, as well as new therapeutic concepts.

Results Mild cases of GO can be treated with only selenium supplementation and a watchful waiting strategy. In the moderate-to-severe active form of GO, primary therapy consists of i. v. steroids (cumulative 4 – 5 g) in combination with orbital irradiation in patients with impaired motility. In patients with insufficient therapeutic response after 6 weeks, treatment should be switched to other immunosuppressive agents. In severe sight-threatening disease, bony orbital decompression is usually necessary. As basic research has improved our understanding of the underlying pathophysiology of GO, it has been possible to develop targeted therapies for GO. Teprotumumab, an IGF-1 receptor antibody, was effective in treating GO patients in a phase III trial and should soon be awarded approval for Europe.

Conclusion The current therapy concept for Gravesʼ orbitopathy is as follows: first anti-inflammatory therapy then surgical correction of the permanent defects. This may soon be modified, due to the use of targeted therapies.
