BACKGROUND Controversy exists regarding the treatment of infants with symptomatic nasolacrimal duct obstruction. One philosophy advocates "early" nasolacrimal duct probing, generally in the office. An alternate strategy advocates medical management until the infant is approximately 12 months old to allow for spontaneous resolution, with those with persistent nasolacrimal duct obstruction usuall...

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...

251 Dacryocystorhinostomy (DCR) for the treatment of nasolacrimal duct obstruction (NLDO) has been practiced for over a century. First described by Addeo Toti in 1904,[1] primary external DCR has traditionally been considered the gold standard technique demonstrating success rates that approach 98% in patients with primary acquired NLDO.[2,3] Caldwell first described the endonasal (non‐endoscop...

Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...

BACKGROUND Contamination of the conjunctiva in association with nasolacrimal duct obstruction is by all accounts a risk factor for infectious endophthalmitis post-cataract surgery. METHODS All patients who underwent cataract day surgery routinely received nasolacrimal duct syringing with normal saline at the Wakayama Medical University Hospital, Japan, from 2011 to 2013. The microorganisms is...

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...
