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 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...

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...

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 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 ...

Objective: To study the age and the sex distribution among the primary and secondarily acquired Nasolacrimal duct obstruction . Methods: we conducted a prospective observational study among randomly selected 100 patients presented with epiphora to ENT department during 2year period ie; from march 2013-march 2015. After confirming presence of Nasolacrimal duct obstruction (NLDO) by opthalmologic...

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...

1. A mucocele of the lacrimal sac, or 2. Chronic dacryocystitis or conjunctivitis due to lacrimal sac obstruction, or 3. Congenital nasolacrimal duct obstruction that cannot be cured by probing (members should be over 1 year of age), or 4. Epiphora (excessive tearing) due to acquired obstruction within the nasolacrimal sac and duct, or 5. Lacrimal sac infection that must be relieved before intr...
