We would be most grateful if you would consider helping to recruit patients with active moderate thyroid eye disease to the CIRTED (Combined Immunosuppression and Radiotherapy in Thyroid Eye Disease) double-blind randomised-controlled Treatment Trial. The trial has been running successfully since January 2006. Patients may be referred to any of our study centres listed below. Referring endocrinologists remain the participant's endocrinologist unless requested otherwise. If you have already assisted our recruitment process we would like to take this opportunity to thank you for your support to date, and hope you will continue to support the trial. For further information about the Trial and our recruitment process, please do not hesitate to contact us or refer to our website via the link below or read about our protocol via doi:10.1186/1745-6215-9-6.
