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...

purpose: to determine the frequency of otolaryngological disorders in patients with congenital nasolacrimal duct obstruction (cnldo) as compared to controls. methods: in this case-control study, 80 children with cnldo (cases) and 80 children without cnldo (controls) were examined for ophthalmological and otolaryngological dosirders. data analysis was performed using pearson chi-square and fishe...

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...

purpose : to present a case of orbital cellulitis secondary to dacryocystitis case report : a 48-year-old postmenopausal lady was referred with a prominent proptosis of the right eye in addition to external ophthalmoplegia. she had one year history of lacrimation. orbital computed tomography (ct) revealed an extraconal infiltration near the medial and inferior orbital wall consistent with orbit...

External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of nasolacrimal duct obstruction (1). Since its introduction by Gibbs in 1967, intubation with silicone tubes has been widely used in lacrimal duct surgery (2). However, effect of silicone intubation on patency of lacrimal system during external DCR in cases of primary nasolacrimal duct obstruction (N...

purpose : to report a patient with retained broken probe tip in the false passage site after nasolacrimal duct (nld) probing case report : a 18-month-baby with epiphora and a nontender mass in the site of lacrimal sac was visited in clinic. she had a history of probing six months ago by another ophthalmologist. the probing was repeated successfully but the mass size didn’t change. the mass was ...
