Graves' ophthalmopathy.

Graves' disease is an inflammatory condition affecting the thyroid gland and the eye. The triad of exophthalmos, goiter, and hyperthyroidism is classic Graves' disease. Each of the signs may appear in an individual patient, although separated by weeks, months, or years. The primary cause of Graves' disease is unknown and cannot be treated satisfactorily; however, the complications may be treated.
