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, ...

This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in Japanese infants treated with conservative management within the 1st year of age. Thirty-five lacrimal ducts in 27 patients diagnosed with CNLDO were included in the study. During the observational period, lacrimal ducts were massaged. As well, antibiotic eye drops, to be admin...

OBJECTIVES The aim of this study was to assess the concomitant perioperative procedures, the causes of nasolacrimal duct obstruction, the success rate, and the complications associated with endonasal dacryocystorhinostomy (ENDCR). METHODS In this single-center retrospective study, 98 patients underwent 104 ENDCRs between January 1994 and February 2006. There were 78 patients with 84 nasolacri...

The current study aimed to determine the efficacy of probing with adjunctive mitomycin C (MMC) as a treatment for nasolacrimal duct obstruction (NLDO) in adults and to study the association of probing success with demographic and obstruction characteristics. This was a prospective, randomized, double-blind, placebo-controlled trial including 140 patients (each with a unilateral NLDO) scheduled ...

We established a chronic dacryocystitis model by injecting of 0.05, 0.1, and 0.15 ml self-curing resin via the lacrimal punctum in rabbits. Animals were randomized into four groups (n = 11 animals/group). The control group received 0.15 ml normal saline. Within three months postinjection, epiphora and eye discharge were observed. At the 90th day postlacrimal passage irrigation, CT dacryocystogr...

OBJECTIVE To assess the impact of the rate of spontaneous resolution of congenital nasolacrimal duct obstruction on the relative cost-effectiveness of deferred nasolacrimal duct probing in a surgical facility (DFPS) compared with an immediate office-based probing surgery (IOPS). METHODS Data from the literature, Medicare 2009 fee schedule, and consensus assumptions were combined to populate a...
