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.
