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 To identify and analyze the role of preoperative computed tomography (CT) in patients with tearing symptoms with nasolacrimal duct obstruction (NLDO). METHODS We retrospectively reviewed the medical records and CT results on 218 patients who complained of tearing symptoms with NLDO between January 2014 and December 2014. All patients were recruited from Kim's Eye Hospital's outpatient...

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...

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...

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...
