Background: Obstruction of the nasolacrimal duct is the most common abnormality of the lacrimal system in childhood leading to epiphora. It is found in about 20% of newborns. If not treated in time, it may be complicated by recurrent conjunctivitis, chronic dacryocystitis, and lacrimal abscess formation. Objectives: To study the outcome and complications of probing for congenital nasolacrimal d...

Probing of the nasolacrimal duct is a common procedure in children with congenital stenosis. Although simple probing of the nasolacrimal duct is successful in a majority of patients, a number of failures occur. In those temporary intubation of the nasolacrimal duct with a silicone drain may solve the problem. We performed silicone intubation in 11 infants under nasal endoscopic control. By this...

ObjectiveRadiological and anatomical study of the Lacrimal apparatus system in one-humped camel of Iran (Camelus Dromedarius) DesignProspective study AnimalsFive heads (cut above the third cervical vertebra) of adult Dromedary camels' cadavers were collected from the slaughterhouse of the Najafabad area of Isfahan Province, Iran. ProceduresThe anatomy of the nasolacrimal duct of onehumped camel...

AIM To evaluate a new approach of recanalisation of nasolacrimal duct obstruction (RC-NLDO) in the treatment of the nasolacrimal duct obstruction (NLDO) and chronic dacryocystitis. METHODS 583 patients with 641 eyes suffering from NLDO and chronic dacryocystitis were enrolled in this study. The RC-NLDO was performed in 506 eyes, with 135 eyes undergoing external dacryocystorhinostomy (EX-DCR)...

PURPOSE To determine whether the lining epithelium of the human lacrimal sac and nasolacrimal duct synthesizes TFF peptides (formerly P-domain peptides, trefoil factors), a family of mucin-associated secretory peptides. METHODS Expression of TFF peptides in human lacrimal sac and nasolacrimal ducts was monitored by reverse transcription-polymerase chain reaction and Western blot analysis. Ant...

PURPOSE To evaluate the effect of the shape of Bowman probes on the success of primary probing for congenital nasolacrimal duct obstruction. MATERIALS AND METHODS Records of 42 nasolacrimal duct obstructions in 37 children who underwent probing with straight Bowman probes (group A) and 128 nasolacrimal duct obstructions in 110 children who underwent probing with Bowman probes manually bent to...

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...

5584 Background: To evaluate the outcomes of dacryocystorhinostomy (DCR) in patients with head and neck tumors. METHODS The clinical records of all 31 patients with head and neck tumors who underwent DCR for nasolacrimal duct blockage at M.D. Anderson Cancer Center between 1999 and 2003 were retrospectively reviewed for outcome and complications of DCR. RESULTS Nasolacrimal duct blockage wa...
