There is significant variation in how ophthalmologists treat children with congenital obstructions of the nasolacrimal ducts. In the United States, some perform an in-office probing procedure on infants, whereas many prefer to wait until after 1 year of age when more than 90% of the obstructions will have resolved spontaneously. Whether or not to instruct parents to massage the lacrimal sac and...

Lacrimal duct obstruction is a common eye disease, and obstruction of the nasolacrimal duct accounts for over 50% of these cases. Nasolacrimal duct obstruction is usually treated surgically. Lacrimal retrograde catheterization is a novel surgical approach with a high success rate and a relatively high recurrence rate. In this study, we examined the postoperative pathological changes in the lowe...

Oncocytoma of the lacrimal sac is a rarely encountered clinical entity. We report the case of a 72-year-old female patient who was diagnosed to have bilateral nasolacrimal duct obstruction during a pre-cataract surgery screening. Subsequently, she underwent bilateral dacryocystectomy. Histopathological examination of the left lacrimal sac revealed a tumour composed of acini lined by oncocytic c...

PURPOSE To define the incidence, clinical characteristics, and outcomes following treatment of symptomatic acquired lacrimal outflow obstruction (SALOO) in Olmsted County, Minnesota, from 1976 to 2000, and to test the hypothesis that the incidence of this disorder increased over this interval. METHODS In this retrospective, population-based study, the Rochester Epidemiology Project was used t...

AIM It appears from the literature that no standardised examination exists for patients with functional nasolacrimal duct obstruction. The role of dacryocystography and lacrimal scintigraphy was compared in the diagnosis and management of these patients. METHOD Patients who were clinically diagnosed as having unilateral or bilateral functional nasolacrimal duct obstruction were prospectively ...

PURPOSE To report the prevalence of amblyopia risk factors in children with congenital nasolacrimal duct obstruction. METHODS A retrospective review of records of children with the diagnosis of congenital nasolacrimal duct obstruction (NLDO), who underwent probing from January 2009 to October 2011, was done. All of them underwent a complete ophthalmic evaluation including cycloplegic refracti...

PURPOSE To assess the results of our protocol of repeated probing for the treatment of congenital nasolacrimal duct obstruction in various presentations. METHODS A total of 1600 patients (1748 eyes) with congenital dacryocystitis (850 boys, 750 girls; age range, 1 month to 48 months [mean 16.54 +/- 12.21 months]) were included. Diagnosis was confirmed by history of tearing, crusting of lids, ...
