Purpose of Study

Thyroid eye disease is an autoimmune disorder affecting approximately 50% of individuals with autoimmune thyroid diseases resulting in enlargement of ocular muscles and may lead to congestion of the eyelids and ocular surface, ocular movement restriction and double vision, and optic nerve compression and loss of vision.

First line medical therapy is oral or intravenous corticosteroids (CS), which several studies have shown results in reduction of soft tissue congestion, but some studies suggesting that ocular restriction or visual loss may still occur in spite of CS therapy.

External beam radiotherapy (XRT) is second line therapy but is controversial, with some studies suggesting benefit in preventing onset of double vision or optic nerve compression while other studies suggest it has no benefit. Most proponents of XRT for TED believe that it is most effective early in the disease evolution. XRT has been shown to be a safe therapy with few side-effects, although retinopathy changes have developed in a small percentage of diabetics and its use is avoided for diabetics.

Combined oral prednisone and XRT has been shown to be more effective in reducing soft tissue inflammation and motility complications than either monotherapy in two different studies.

To date there have been no trials comparing combined XRT and iv CS with iv CS alone for early progressive TED to identify potential benefit in reducing the severity of motility disorders or preventing the onset of dysthyroid optic neuropathy. That is the purpose of this study.
