PURPOSE This prospective study was designed to establish whether it is more effective to treat symptomatic congenital nasolacrimal duct obstruction by probing, or high-pressure irrigation, or both. METHODS During the period February 1991 to January 1999, 228 infants (300 nasolacrimal ducts) were examined (132 males, 96 females, age range 12-13 months). These patients were divided into three g...

BACKGROUND AND PURPOSE Epiphora, or tearing due to primary acquired nasolacrimal duct obstruction (PANDO), is increasingly being treated with balloon dilatation. The cause of PANDO is unknown, but a small diameter of the bony nasolacrimal canal might be one of the etiologic factors. The purpose of this study was to determine the normal distribution of diameters of the bony canal and to ascertai...

BACKGROUND To report the clinical experience and success rate with Ritleng intubation system in patients with congenital nasolacrimal duct obstruction. METHODS Twenty-four patients (32 eyes) with congenital nasolacrimal duct obstruction treated with the Ritleng intubation system were enrolled in this study. The mean age was 20.1+/-9.6 months. The technique involved introduction of a Prolene m...

Aim: To investigate the efficacy of probing in adults with epiphora due to nasolacrimal duct obstruction. Patients and methods: A retrospective study was conducted to investigate the efficacy of probing and irrigation of 72 lacrimal systems in 60 adults with nasolacrimal duct obstruction where epiphora was the only symptom. At follow-up, the procedure was considered successful if the epiphora h...

PURPOSE To compare the success rate of monocanalicular versus bicanalicular silicone intubation of the nasolacrimal duct for congenital nasolacrimal duct obstruction (CNLDO). METHODS In a prospective randomized clinical trial, 70 eyes of 57 children with CNLDO underwent either monocanalicular silicone intubation (MCI) (n = 35 eyes) or bicanalicular silicone intubation (BCI) (n = 35 eyes). All...

OBJECTIVE To determine the success of probing for congenital nasolacrimal duct obstruction in children aged under 10 years. DESIGN A retrospective study. MATERIAL AND METHOD The medical records of all children aged under 10 years diagnosed with congenital nasolacrimal duct obstruction between 1997 and 2007 who underwent probing and irrigation under general anesthesia were reviewed. Successf...
