Computed exophthalmometry is an accurate and reproducible method for the measuring of eyeballs' protrusion

In some patients with intact lateral orbital rims the results of computed exophthalmometry correlated with the measurements from the Hetrel exophthalmometer. The analysis of the triple measurements with computed exophthalmometry revealed no significant difference in the value of standard deviation of the results in patients with intact and pathological orbits. In comparison with the Hertel-type exophthalmometry, the proposed method demonstrated very low variability and high repeatability of the measurements. The difference of 0.10-0.87 mm in the eyeballs protrusion should be considered as normal. Computed exophthalmometry is an accurate and reproducible method, which can be used for the measurements of eyeballs' protrusion.
