Nasolacrimal Duct Oncocytoma: An Unusual Cause of Chronic Epiphora

Diagnosis of epiphora and management of acquired nasolacrimal duct obstruction

Microbiology of primary acquired nasolacrimal duct obstruction: simple epiphora, acute dacryocystitis, and chronic dacryocystitis

PURPOSE The aim of this study was to determine the microbiology of primary acquired nasolacrimal duct obstruction (PANDO) and its antimicrobial susceptibilities. METHODS Ninety-three patients (100 eyes) diagnosed with PANDO, categorized as acute, chronic dacryocystitis, or simple epiphora, were prospectively enrolled. Lacrimal sac contents were cultured for aerobic and anaerobic bacteria and ...

Cystic dilation of the distal end of the nasolacrimal duct: underrated cause of epiphora in adults and its endoscopic treatment.

Epiphora is a frequent reason for ophthalmologic consultation. Among the multiple causes, obstructions of the lacrimal excretory system are common. Sacal and postsacal obstructions are much more frequent than presacal obstructions. Obstruction at the level of the Hasner's valve is rare and likely underestimated. The authors report the clinical history and the imaging of 3 patients with a cystic...

CONGENITAL NASOLACRIMAL DUCT OBSTRUCTION: An Optometric Perspective

Congenital Nasolacrimal Duct Obstruction is a frequent occurrence in newborns. This article discusses the incidence, etiology and management of congenital nasolacrimal duct obstruction. Though surgical intervention may be needed at times, a conservative approach is often
