PURPOSE To characterize the outcomes of initial and repeated office-based probing as a primary treatment for congenital nasolacrimal duct obstruction (CNLDO) in children. METHODS The medical records of patients who underwent nasolacrimal duct office-based probing for CNLDO between March 2004 and January 2008 were reviewed retrospectively. Nasolacrimal duct probing was performed on 244 eyes fr...

A 31-year-old man with epiphora and mucous discharge from a traumatic lacrimal fistula underwent a computed tomographic dacryocystogram, revealing a fistula extending from the anterior ethmoid air cells through the lacrimal sac to the overlying skin with coexisting nasolacrimal duct obstruction. Endoscopic dacryocystorhinostomy enabled complete marsupialization of the lacrimal sac and agger nas...

The rabbit’s anatomy of the nasolacrimal system is unique, with a single lacrimal punctum and a tortuous nasolacrimal duct. Inflammation of the nasolacrimal duct, dacryocystitis, can be caused by primary infection with bacteria from the respiratory tract, secondary to infectious conjunctivitis or nasolacrimal duct obstruction. The latter can occur due to the rabbit’s anatomy features, the tears...

BACKGROUND Dacryocystorhinotomy (DCR) is a common procedure used to treat nasolacrimal duct obstruction. The modern external DCR, in which the lacrimal sac is opened directly into the nasal cavity, was first described in 1904 by Toti. Since that time, DCR techniques have evolved, including a transnasal endoscopic approach that has gained popularity in parallel with the growth of endoscopic sinu...

Lacrimal scintigraphy (LS) was performed on asymptomatic lacrimal drainage systems and the results were evaluated to understand the physiology of lacrimal drainage. It was found that a physiological obstruction can exist at the level of the nasolacrimal duct in normal asymptomatic individuals, and it is suggested that this obstruction is due to the resistance offered by the valve of Hasner, whi...

PURPOSE To present our initial results in the treatment of nasolacrimal obstruction by placing a polyurethane stent. METHODS 74 nasolacrimal stents were implanted under fluoroscopic guidance in obstructed nasolacrimal systems of 64 patients. Dacryocystography and CT were used to verify the position and patency of the stents. Mean follow-up was 15 months. Clinical examinations were done at the...

A review of endoscopic dacryocystorhinostomy (EDCR) performed in University Hospital from 1998 till early 2001 were carried out. They were reviewed for indication, functional results, complications and other associated factors. Eleven patients (6 female and 5 male) were reviewed. All had unilateral nasolacrimal duct (NLD) obstruction (6 right, 5 left). Their ages range from 6 to 73 years. All 1...

Objective: To study the age and the sex distribution among the primary and secondarily acquired Nasolacrimal duct obstruction . Methods: we conducted a prospective observational study among randomly selected 100 patients presented with epiphora to ENT department during 2year period ie; from march 2013-march 2015. After confirming presence of Nasolacrimal duct obstruction (NLDO) by opthalmologic...

Objective: To compare the results and complications of monocanalicular and bicanalicular Ritleng intubation under endoscopic guidance in patients with congenital nasolacrimal duct obstruction. Methods: This prospective study was performed on 24 patients with congenital NLD obstruction in the age between (2-5 years), divided into 2 groups. Group (A) underwent monocanalicular intubation, while gr...
