Comparison of clinical examination with orbital MRI evaluation in patients with thyroid orbitopathy - do we need imaging and when?

The frequency of Graves’ orbitopathy (GO) in patients with Graves’ disease (GD) depends on the method of assessment. Diagnosis based on clinical symptoms is made in about 30-50% patients, more often (70%) after ophtalmological examination with evaluation of intraocular pressure, whereas MRI reveals GO in up to 90%. Proper identification of active phase of the disease is crucial.
