    Description / Table of Contents: Résumé Les récents progrès en ophtalmologie tels que la dilatation par ballonnet, la pose de sondes, les traitements au laser, l'endoscopie du système lacrymal accroissent la nécessité d'une connaissance anatomique précise de ce système ; dans cette étude morphométrique, les mesures du système de drainage lacrymal ont été réalisées par tomodensitométrie en coupes fines (CT); l'étude portait sur 147 patients indemnes de toute pathologie du système de drainage lacrymal. La longueur moyenne du conduit lacrymal était de 11,2±2,6 mm (limites : 6–21 mm) ; le diamètre le plus réduit était de 3,7±0,7 mm (limites : 2–7 mm). La longueur moyenne du sac lacrymo-nasal était de 11,8 mm±2,5 mm (limites 6–18 mm) ; la largeur du sac n'excédait pas 4 mm, en dehors d'un remplissage par l'air. La présence d'air a été décelée dans le sac ou le conduit chez 43 sujets (29,3 %). La connaissance de la morphométrie du système de drainage lacrymal permet à l'ophtalmologiste de planifier avec précision une intervention sur le système en évitant des manœuvres intempestives.
    Notes: Summary Recent developments in ophthalmology such as balloon dilatation, stent implantation, laser therapy and endoscopy of the lacrimal drainage system raise the need for a detailed anatomical knowledge of this system. In this study morphometric measurements of the lacrimal drainage system were performed with thin-section axial computed tomography (CT) examinations in 147 patients with no signs of pathology related to the lacrimal drainage system. The mean length of the nasolacrimal duct measured 11.2±2.6mm (range: 6–21 mm), the narrowest diameter was 3.7±0.7 mm (range: 2–7 mm). The mean length of the nasolacrimal sac was 11.8±2.5 mm (range: 6–18 mm). The width of the nasolacrimal sac did not exceed 4 mm unless filled with air. In 43 (29.3%) of the subjects air was visible within the nasolacrimal sac or duct. The knowledge of the morphometry of the lacrimal drainage system enables the ophthalmologist to plan intervention on the lacrimal drainage system precisely and avoid unnecessary manipulations.
