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.

OBJECTIVE To determine the outcome of late Nasolacrimal Duct (NLD) probing in children 2 years and above and to identify the cause of failure in these children. STUDY DESIGN Quasi- experimental. PLACE AND DURATION OF STUDY Shri Ganapati Netralaya, Jalna, India, from January 1999 to June 2003. PATIENTS AND METHODS Clinical diagnosis of Congenital Nasolacrimal Duct Obstruction (CNLDO) was d...

A total of 585 infants and children, with 802 con­ genital nasolacrimal duct obstructions, were treated during a ten year old period, from June 1985 at StMichael's and St.Anne's hospitals in Colombo. All patients were initially treated medi­ cally (massage), and failures were subjected to probing, and when probing failed, to dilatation. Resolution with medical therapy was 86% in pa­ tients unde...

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...
