Diagnosis of Exophthalmos
Exophthalmos may be suspected from the appearance of the eyes. You may be referred to an eye specialist (ophthalmologist) for clarification. Normally you will have a blood test to see if your thyroid gland is functioning properly.
The ophthalmologist may check to see if you can look upwards without moving your eyebrows and measure the degree of eyeball protrusion with an instrument called an exophthalmometer.
A CT (computed tomography) scan may be used to examine the orbit (eye socket). An MRI (magnetic resonance imaging) scan may be used to examine the eye socket. This will show up any abnormalities such as a tumour.
