Abstract

PURPOSE
To determine the size range of lacrimal glands calculated from Brain CT angiography.
METHODS
A retrospective review of 107 CT scans of 214 orbits was performed. Aquaris Intuition Viewer software was used to calculate the volumes.
RESULTS
The mean volume of the lacrimal gland was 0.655 cm3 in right orbits and 0.595 cm3 in left orbits, 0.616 cm3 in men and 0.625 cm3 in women. There was a significant difference between right and left (p = 0.012) but no difference between men and women (p = 0.725). Linear regression analyses revealed that there was an inverse relationship between gland volume and age (Pearson r = -0.433, p < 0.001).
CONCLUSIONS
This is the first study to report the normal volume range of Korean lacrimal glands as measured by CT scans. A difference was detected in the volume between right and left lacrimal glands. The volume of the lacrimal gland decreased with age, and there were no gender differences.
