Objective: Detailed anatomical information about the nasolacrimal duct elucidates the etiology of primary acquired nasolacrimal duct obstruction (PANDO) and contributes to the clinic for effective treatment. This study aims to present norm data and determine differences between genders by examining the morphometry of the nasolacrimal duct in the Turkish population consisting of healthy individuals. Methods: Computed tomography images taken in a healthy Turkish population of 150 people, 79 women and 71 men, were included in the study retrospectively. Images were modeled and analyzed using 3D Slicer version 5.2.2. The volume, surface area, vertical and horizontal length of the right and left side nasolacrimal duct at the starting point, and the distance between both nasolacrimal duct were evaluated. The data were analyzed with the SPSS package program. Results: In this study, the average volume of the right nasolacrimal duct was 219.28±77.53 mm³ in male and 193.82±75.71 mm³ in female. The average volume of the left nasolacrimal duct was 213.14±73.82 mm³ in male and 190.34±82.54 mm³ in female. In both genders, vertical and horizontal length were statistically larger on the right side compared to the left side, but other parameters did not differ significantly for both genders when comparing the right and left sides (p<0.05). There was a statistically significant high positive correlation between the volume and surface area of the right nasolacrimal duct in male and female gender (p<0.05, r=0.961, r=0.957). There was a statistically significant high positive correlation for the left nasolacrimal duct only in male gender (p<0.05, r=0.954). Conclusion: Differences between genders were detected in nasolacrimal duct morphometry. These findings allow the differentiation and understanding of acquired obstructions and safe surgical approaches.
