abstract

  • CT 3-dimensional volumetric software can be used to accurately measure the nasolacrimal duct volume in patients with obstruction. Both the absence of a significant difference in patient's and control's nasolacrimal duct volumes and the overlap in range between the 2 groups imply that the volume of the tear duct is likely not related to the etiology of obstruction. The increase in volume seen in females with obstruction may be due to expansion of the bony canal during the postmenopausal years. The exact etiology of primary nasolacrimal duct obstruction requires further investigation.
