BACKGROUND AND PURPOSE Several techniques have been used to image the nasolacrimal system, providing functional (dacryoscintigraphy) or morphologic (dacryocystography, CT dacryocystography [CTD]) information. Using gadopentetate dimeglumine-diluted solution injected into the lacrimal canaliculus or instilled into the conjunctival sac, we compared the sensitivity of MR dacryocystography (MRD) wi...

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...

PURPOSE To evaluate the nasolacrimal duct reconstitution with radio frequency for restoration of lacrimal flow in cases of nasolacrimal duct obstruction. METHODS The procedure was carried out in 16 eyes of 16 patients (13 women and 3 men) by the same surgeon, with monopolar high-frequency device at 450 kHz and 150 W, with local anesthesia under sedation. Inclusion criteria were lower lacrimal...

OBJECTIVE To assess the results of microsurgical endonasal dacryocystorhinostomy with long-term insertion of single or double bicanalicular silicone tubes in canalicular (presaccal) and ductal (postsaccal) stenosis of the nasolacrimal duct system. DESIGN Retrospective follow-up of case series between 1992 and 1996. PATIENTS Thirty-eight patients were included in the study: 19 with ductal st...

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...

The authors report their experience with an infant presenting with an infected nasolacrimal duct mucocele, emphasizing correlation of clinical, CT, and surgical findings. CT is the imaging modality of choice to demonstrate the triad of 1) a cystic medial canthal mass, 2) dilatation of the nasolacrimal duct, and 3) a submucosal nasal cavity mass; findings which are diagnostic of this entity. A b...

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....
