  • Abstract
  • Look Inside

 We tried to identify the optimal depth of insertion of lacrimal probe and that of intranasal endoscope to examine the nasolacrimal opening. A total of 26 cases of nasolacrimal obstruction and 2 sides of cadavers were subjected to the study. We used a hard endoscope with a diameter of 2.7mm and visual field opening of 30 degrees. The distance from the lacrimal punctum to the nasolacrimal opening ranged from 29mm to 40mm. It was necessary to insert the endoscope for 3cm to examine the nasolacrimal opening and for 4cm to reach the opening.
