As computerised tomography is now accepted as a method of choice for the investigation of suspected orbital masses, measurement of the degree of proptosis (exophthalmos) should be useful in assessing response to therapy. 2,7,8 Exophthalmometry is valuable in diagnosing and treating TAO. Owing to the rigid bony structure of the orbit with only anterior opening for expansion, any increase in orbital contents taking place from the side or from behind will displace the eyeball forward. Naugle exophthalmometer measures the difference in proptosis between the two eyes rather than absolute measure with the Hertel method. Patients should be monitored in intervals tailored to the degree of exophthalmos and complications arising from this ocular malady.
