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...

Observation is a simple and reliable tool with the clinician. The level of tears, position of puncta, lids and eyelashes should be noted. Obstruction of the tear drainage system can be acquired or congenital, it is important to rule out acquired causes of tearing such as corneal, lid or lash abnormalities. Lacrimal obstruction problems can be divided as related to upper (puncta to lacrimal sac)...

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...

PURPOSE To compare conventional and endoscopic probing for congenital nasolacrimal duct obstruction in infants. METHODS Conventional probing was performed in 22 eyes of 18 patients, age range 7-14 months (mean 11.4 months). Probing was done with intranasal endoscopic visualization in 18 eyes of 14 patients, age range 7-13 months (mean 11.2 months). All were primary probing cases. RESULTS Af...

Probing is a reliable surgical intervention for the management of congenital nasolacrimal duct obstruction (CNLDO). However, it is a blind procedure that carries the risk of false passage formation. Moreover, its success rate is variable, with unexplained causes of failure. Recent literature suggests the use of nasal endoscopic-assisted probing to minimize nasal mucosal trauma, decreases the ch...

purpose: to determine long-term outcomes of probing in adult patients with nasolacrimal duct (nld) obstruction. methods: patients older than 20 years admitted in labaffinejad hospital with complete nasolacrimal duct obstruction were studied. the selected patients underwent probing under local anesthesia and cases with successful nld probing enrolled the study. patients were examined during the ...

Introduction Mucoceles are benign expansive cystic formations, composed of a mucus-secreting epithelium (respiratory or pseudostratified epithelium). Nasolacrimal mucocele occurs in a small proportion of children with nasolacrimal duct obstruction and is characterized by a cystic mass in the medial canthus with dilation of the nasolacrimal duct; although dacryocystoceles are rare in adults, the...

Developmental anomalies of the nasolacrimal drainage system typically manifest early in childhood with epiphora and occasionally infection. Although the majority of cases of congenital nasolacrimal obstruction resolve spontaneously with conservative medical management, certain anomalies require operative intervention. Included in this latter group are dacryocystoceles or nasolacrimal duct cysts...
