Nonthyropathic exophthalmos.

Although most cases of bilateral exophthalmos and many cases of unilateral exophthalmos are related to hyperthyroidism, there are numerous other diagnostic possibilities. These include tumors, hemorrhage, vascular anomalies and infections. Exophthalmometric measurements are useful in diagnosis and follow-up. The determination of a nonthyroidal etiology for exophthalmos may require sophisticated radiologic and other techniques, as well as a team approach.
