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...

BACKGROUND AND PURPOSE Epiphora, or tearing due to primary acquired nasolacrimal duct obstruction (PANDO), is increasingly being treated with balloon dilatation. The cause of PANDO is unknown, but a small diameter of the bony nasolacrimal canal might be one of the etiologic factors. The purpose of this study was to determine the normal distribution of diameters of the bony canal and to ascertai...

PURPOSE To investigate the diagnostic effectiveness of dacryoscintigraphy in children with tearing; to evaluate tear clearance rate as a diagnostic factor of dacryoscintigraphy in children with tearing; and to analyze the results of treatment according to dacryoscintigraphic findings in children with tearing. METHODS Between January 2010 and April 2014, 176 eyes of 88 children with tearing (4...

Dacryocystorhinostomy (DCR) is the standard procedure for treatment of acquired nasolacrimal duct obstruction (NLDO), which can be performed with an external or endonasal approach. Numerous variations DCR have been described in literature that report varying rates success. The aim this study to describe approach and success rate DCR, nasal mucosa, bone lacrimal mucosa are sequentially removed.

Background and Objectives: Primary acquired nasolacrimal duct obstruction (PANDO) is a common ocular problem. Clinical presentation can range from simple tearing to a life-threatening condition. The exact pathophysiology of obstruction is not completely understood. In this study, therelationship between PANDO and nasal mucosal goblet cells was investigated.  Materials & Methods: In this case-c...

PURPOSE The aim is to compare the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN DCR) with external DCR (EXT-DCR) in the treatment of nasolacrimal duct obstruction (NLDO) in children. METHODS A retrospective, comparative chart analysis of all consecutive children <16 years after EXT-DCR or NEN-DCR between June 2012 and February 2016. RESULTS Seventy-one children (79 eyes) und...
