A prospective study of the effects of radioiodine therapy for hyperthyroidism in patients with minimally active graves' ophthalmopathy.

Context: Radioiodine is an effective and safe treatment for hyperthyroidism but has been implicated as a risk factor for deterioration or new presentation of Graves' ophthalmopathy (GO). Prophylactic glucocorticoids appear to prevent this effect.

Objective: The objective of this study was to document the course of GO after radioiodine therapy.

Multi-center study on the characteristics and treatment strategies of patients with Graves' orbitopathy: the first European Group on Graves' Orbitopathy experience.

Unlabelled: To improve management of patients with Graves' orbitopathy, a multi-center collaborative approach is necessary in order to have large enough sample sizes for meaningful randomized clinical trials. This is hampered by a lack of consensus on how to investigate the eye condition. The European Group on Graves' Orbitopathy aims to overcome this and has designed a preliminary case record form (CRF) to assess Graves' orbitopathy patients.
