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...

. PURPOSE Dacryocystorhinostomy (DCR) is the standard surgical treatment for adult nasolacrimal duct obstruction. There have been relatively few studies of closed nasolacrimal duct intubation in adults. The aim of this study was to determine rates of anatomic patency following this procedure. METHODS The authors carried out a survey of all patients undergoing closed nasolacrimal duct intuba...

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...

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...

The eye has two sets of structures that produce tears. Smaller tear glands help maintain a baseline level of moisture on the surface of the eye. Unfortunately, inflammatory conditions like rheumatoid arthritis, Sjogrens disease as well as aging and menopause lead to decreased tear production. As tear production diminishes, the surface of the eye starts to dry out. Further, inflammation of the o...
