  • Abstract
  • Look Inside

We examined 17 cases (22 lesions) with stenosis or obstruction in the lacrimal drainage system with the use of computerized tomography (CT). In idio pathic cases, the site of obstruction was located either in the upper nasolacrimal duct or at the junction of the lacrimal sac and the naso-lacrimal duct. In post-traumatic cases, it was located in the lower nasolacrimal duct.

The obstructed areas appeared as homogenous in CT image with CT values ranging between +60 and +80. These findings were suggestive of granula-tion tissue. The stenosed areas appeared, on the other hand, as areas of unequal density. Lacrimal passage appeared to be maintained through the low-density portion. The CT values of the lacrimal sac was around +40 in dacryocystitis and around +20 to +30 other cases.
