congenital nasolacrimal duct obstruction (cnldo) is a common disease in children. the classic treatment of cnldo is probing that was done around one year old. however, controversy exists regarding the outcome of probing in children older than one year. this study aimed to find the cure rate of initial probing for cnldo and identify factors producing the failure rate in old age. in this retrospe...

A Labrador retriever was evaluated because of chronic mucopurulent discharge from the left eye. A foreign body was identified in the nasolacrimal duct by use of dacryocystorhinography. Attempts to alleviate the inflammation by use of flushing and administration of antimicrobials were unsuccessful. At surgery, the infraorbital foramen was used as a landmark for a skin incision, because the nasol...

PURPOSE To evaluate the efficacy of Palmaz balloon-expandable metallic stents for the maintenance of luminal patency in the treatment of recurrent nasolacrimal duct, obstructions after failed transluminal balloon dilatation. METHODS Metallic stents were implanted in the nasolacrimal duct of four patients with recurrent epiphora. All the patients had already undergone transluminal balloon dila...

The clinical, light microscopic, ultrastructural, and immunohistologic findings of a neurilemmoma encroaching upon the nasolacrimal duct are presented. This is the first reported case of this rare tumour of the nasolacrimal duct where the diagnosis has been confirmed by electron microscopy and immunohistochemical techniques.

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...

BACKGROUND Endoscopic extended maxillary mega-antrostomy (EMMA) is a mucosal sparing technique that allows maxillary drainage by gravity, with a reported symptomatic nasolacrimal duct injury incidence of 0-4%, based on history alone. Injury to the nasolacrimal duct is known to cause epiphora, a complication that is rare but more often seen in this revision surgery. OBJECTIVE The goal of this ...

A wide array of pathogenic factors has been associated with lacrimal drainage system obstruction including inflammatory conditions originating from the eye, conjunctiva, lacrimal mucosa, nose and paranasal sinuses; trauma; congenital abnormalities; radiotherapy and neoplasms. Inflammatory conditions initially cause lac-rimal mucosal swelling but may lead to fibrotic narrowing or obstruction of ...
