Chronic dacryocystitis results very often from obstruction to the nasolacrimal duct. It manifests as epiphora or watering of the eyes. The lacrimal sac gets expanded and also the wall of the sac gets thickened as a result of collection of mucopus due to obstruction of the nasolacrimal duct. Treatment of chronic dacryocystitis is by a surgical approach which consists of making an opening between...

Lacrimal duct obstruction is a common eye disease, and obstruction of the nasolacrimal duct accounts for over 50% of these cases. Nasolacrimal duct obstruction is usually treated surgically. Lacrimal retrograde catheterization is a novel surgical approach with a high success rate and a relatively high recurrence rate. In this study, we examined the postoperative pathological changes in the lowe...

PURPOSE We report a very good outcome in a 44-year-old woman in whom cancer was missed as the cause of nasolacrimal duct obstruction and dacryocystitis and which was deemed inoperable after spreading to the cavernous sinus. CASE REPORT The patient was referred to our unit 12 months following uneventful right dacryocystorhinostomy for nasolacrimal duct obstruction. This had been complicated by...

The long term results of probing for congenital nasolacrimal duct obstruction were reviewed using a parental questionnaire issued to both treated and age-matched control groups. On follow up 4-13 years after probing in childhood 30% of patients still had symptoms of epiphora or discharge. Surprisingly, a similar high symptom rate was found in the controls, such that there was no statistically s...

purpose: to compare success rates of external dacryocystorhinostomy (dcr) with and without bicanalicular silicone intubation for management of primary acquired nasolacrimal duct obstruction. methods: in a randomized clinical trial study, 52 patients with primary acquired nasolacrimal duct obstruction underwent external dcr. patients were randomly enrolled into two groups. in the 1st group, exte...

Here we report a case of nasolacrimal obstruction resulting from rice grains ingested over many years that had formed an obstructive mass. This is a hitherto unreported cause of nasolacrimal obstruction. We exclusively treated the obstruction safely with repeated irrigation with physiological saline. Although there have been various reports on new techniques such as the blind insertion of a bou...

PURPOSE This prospective study was designed to establish whether it is more effective to treat symptomatic congenital nasolacrimal duct obstruction by probing, or high-pressure irrigation, or both. METHODS During the period February 1991 to January 1999, 228 infants (300 nasolacrimal ducts) were examined (132 males, 96 females, age range 12-13 months). These patients were divided into three g...

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)...
