Effect of orbital radiotherapy on the outcome of surgical orbital decompression for thyroid-associated orbitopathy (TAO): a retrospective study in 136 patients.

Purpose: In patients with moderate to severe thyroid-associated orbitopathy (TAO), orbital radiation therapy (ORT) can prevent disease progression. In the sequelae stage, orbital decompression surgery can be useful in case of functional discomfort. The aim of this study was to evaluate the effect of orbital ORT on the outcomes of decompression surgery.
