purpose: to determine long-term outcomes of probing in adult patients with nasolacrimal duct (nld) obstruction. methods: patients older than 20 years admitted in labaffinejad hospital with complete nasolacrimal duct obstruction were studied. the selected patients underwent probing under local anesthesia and cases with successful nld probing enrolled the study. patients were examined during the ...

INTRODUCTION Acquired nasolacrimal duct obstruction is a common disorder affecting adults. Its pathogenesis is not known. We hypothesize that facial and bony asymmetry can contribute to the unilaterality of the nasolacrimal duct obstruction. MATERIALS AND METHODS Retrospective study was done on all patients with acquired nasolacrimal duct obstruction who presented to our practice from January...

purpose: to evaluate the nature of obstruction in difficult irrigation after probing for congenital nasolacrimal duct obstruction (cnldo). methods: in a prospective interventional study, the nature of obstruction in 75 eyes of 68 children aged between 12 and 23 months with cnldo who had difficult irrigation after probing was evaluated. all patients underwent monocanalicular silicone intubation....

PURPOSE To evaluate the results of nasolacrimal polyurethane stent implantations for the treatment of primary acquired nasolacrimal duct obstruction, and to determine the effects of various surgical procedures, including stent removal, in subsequent nasolacrimal duct obstruction. METHODS This study included 15 patients who had nasolacrimal polyurethane implantations for the treatment of prima...

Congenital Nasolacrimal Duct Obstruction is a frequent occurrence in newborns. This article discusses the incidence, etiology and management of congenital nasolacrimal duct obstruction. Though surgical intervention may be needed at times, a conservative approach is often

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20141230-04 It is remarkable that what appears as a straightforward ocular condition, congenital nasolacrimal duct obstruction, lacks consensus among pediatric ophthalmologists in many aspects of its management. This was clearly demonstrated in the survey by Dotan and Nelson in this issu...

purpose:  to determine the safety and efficacy of mitomycin-c injection into the lacrimal duct for treatment of partial nasolacrimal duct obstruction in adults. method: this is a before-after clinical trial performed on 20 patients with partial primary acquired nasolacrimal duct obstruction. we injected 1.5 ml of mitomycin-c 0.2 mg/ml into the lacrimal duct and repeated it with concentration of...

Developmental anomalies of the nasolacrimal drainage system typically manifest early in childhood with epiphora and occasionally infection. Although the majority of cases of congenital nasolacrimal obstruction resolve spontaneously with conservative medical management, certain anomalies require operative intervention. Included in this latter group are dacryocystoceles or nasolacrimal duct cysts...
