Answer

Computed tomography scanning or magnetic resonance imaging (of the orbits) may be necessary in the evaluation of proptosis. If routinely performed, most patients have evidence of ophthalmopathy, such as an increased volume of extraocular muscles and/or retrobulbar connective tissue. These techniques are useful to monitor changes over time or to ascertain the effects of treatment. Careful monitoring is required after using iodinated contrast agents as they may affect ongoing treatment plans.
