This was clearly demonstrated in the survey by Dotan and Nelson in this issu...

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...

purpose: to evaluate refractive state in patients with unilateral congenital nasolacrimal duct obstruction. methods: in this descriptive prospective study, patients with unilateral congenital nasolacrimal duct obstruction scheduled for surgery were enrolled over a period of two years (2007-2009). cycloplegic refractive error in both eyes was measured under anesthesia before surgery (probing, si...

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 ...

purpose: primary acquired nasolacrimal duct obstruction (pando) is an acquired disease characterized by persistent symptoms such as tearing, mucus secretion, recurrent conjunctivitis and eye irritations. different etiologies such as conjunctival infections, and nasal and sinus diseases have been proposed. pathological studies have revealed inflammation, vascular congestion and edema in the earl...

purpose: to compare the success rate of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for the management of primary acquired nasolacrimal duct obstruction. methods: in this study, 51 eyes from 50 patients who were diagnosed with primary acquired nasolacrimal duct obstruction underwent external dcr. patients with history of trauma and/ or surgery in the ...

introduction: this study was done to determine the site of obstruction in lacrimal drainage system in asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. methods:dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99mtc) in 34 patients suffering from unilateral or bil...

Background: To report the clinical experience and analysis of our results with Ritleng intubation system in patients with congenital and acquired nasolacrimal duct obstruction. Methods: Silicone intubation with the Ritleng lacrimal system was performed in 17 patients (20 eyes) from March 2001 to March 2003 to relieve nasolacrimal duct obstruction following the failure of nasolacrimal duct probi...
