PURPOSE: To evaluate dacrycystographic examination in patients with suspicion of lacrimal apparatus obstruction. METHODS: A retrospective study was performed to evaluate dacryocystographies of 100 adults suspected of nasolacrimal duct obstruction at the "Faculdade de Medicina de Botucatu - UNESP". The data were submitted to descriptive statistical analysis and chi-square test. RESULTS: The patients were mainly female, over 60 years old, presenting a low obstruction located at Arlt's sinus, with a grade 2 or 3 lacrimal sac. Lacrimal pathways with normal tear drainage, with or without dilatation and nasal alterations such as concha hypertrophy were also observed. CONCLUSION: Dacryocystographic evaluation was important to show the level of obstruction, the presence of dilatation of the lacrimal sac, as well as alterations in nearby structure. This information might influence the adopted surgical technique and the final treatment results.
