congenital nasolacrimal duct obstruction (cnldo) is a common disease in children. the classic treatment of cnldo is probing that was done around one year old. however, controversy exists regarding the outcome of probing in children older than one year. this study aimed to find the cure rate of initial probing for cnldo and identify factors producing the failure rate in old age. in this retrospe...

purpose: to evaluate the nature of obstruction in difficult irrigation after probing for congenital nasolacrimal duct obstruction (cnldo). methods: in a prospective interventional study, the nature of obstruction in 75 eyes of 68 children aged between 12 and 23 months with cnldo who had difficult irrigation after probing was evaluated. all patients underwent monocanalicular silicone intubation....

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...

Congenital Nasolacrimal Duct Obstruction is a frequent occurrence in newborns. This article discusses the incidence, etiology and management of congenital nasolacrimal duct obstruction. Though surgical intervention may be needed at times, a conservative approach is often

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20141230-04 It is remarkable that what appears as a straightforward ocular condition, congenital nasolacrimal duct obstruction, lacks consensus among pediatric ophthalmologists in many aspects of its management. This was clearly demonstrated in the survey by Dotan and Nelson in this issu...

Background: To report the clinical experience and analysis of our results with Ritleng intubation system in patients with congenital and acquired nasolacrimal duct obstruction. Methods: Silicone intubation with the Ritleng lacrimal system was performed in 17 patients (20 eyes) from March 2001 to March 2003 to relieve nasolacrimal duct obstruction following the failure of nasolacrimal duct probi...

DOS Times Vol. 12, No. 10 April, 2007 Congenital nasolacrimal duct obstruction is the most common cause of epiphora in children. In the majority of cases, it is due to an obstruction at the lower end of the NLD. The Ophthalmologist should have the throrough understanding of the developmental anatomy, abnormalities of the nasolacrimal system and other congenital disorders for appropriate diagnos...

1. A mucocele of the lacrimal sac, or 2. Chronic dacryocystitis or conjunctivitis due to lacrimal sac obstruction, or 3. Congenital nasolacrimal duct obstruction that cannot be cured by probing (members should be over 1 year of age), or 4. Epiphora (excessive tearing) due to acquired obstruction within the nasolacrimal sac and duct, or 5. Lacrimal sac infection that must be relieved before intr...
