Calculated Brain CT Angiography Volumes of Lacrimal Glands in Normal Korean Orbits

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 cm in right orbits and 0.595 cm in left orbits, 0.616 cm in men and 0.625 cm in women. There was a significant difference between right and left (<EM>p </EM>= 0.012) but no difference between men and women (<EM>p</EM> = 0.725). Linear regression analyses revealed that there was an inverse relationship between gland volume and age (Pearson r = -0.433, <EM>p </EM>&lt; 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.&nbsp;J Korean Ophthalmol Soc 2014;55(10):1413-1417
