Oncocytoma of the lacrimal sac is a rarely encountered clinical entity. We report the case of a 72-year-old female patient who was diagnosed to have bilateral nasolacrimal duct obstruction during a pre-cataract surgery screening. Subsequently, she underwent bilateral dacryocystectomy. Histopathological examination of the left lacrimal sac revealed a tumour composed of acini lined by oncocytic c...

Probing is a reliable surgical intervention for the management of congenital nasolacrimal duct obstruction (CNLDO). However, it is a blind procedure that carries the risk of false passage formation. Moreover, its success rate is variable, with unexplained causes of failure. Recent literature suggests the use of nasal endoscopic-assisted probing to minimize nasal mucosal trauma, decreases the ch...

AIM It appears from the literature that no standardised examination exists for patients with functional nasolacrimal duct obstruction. The role of dacryocystography and lacrimal scintigraphy was compared in the diagnosis and management of these patients. METHOD Patients who were clinically diagnosed as having unilateral or bilateral functional nasolacrimal duct obstruction were prospectively ...

PURPOSE To evaluate the effect of the shape of Bowman probes on the success of primary probing for congenital nasolacrimal duct obstruction. MATERIALS AND METHODS Records of 42 nasolacrimal duct obstructions in 37 children who underwent probing with straight Bowman probes (group A) and 128 nasolacrimal duct obstructions in 110 children who underwent probing with Bowman probes manually bent to...

The long term results of probing for congenital nasolacrimal duct obstruction were reviewed using a parental questionnaire issued to both treated and age-matched control groups. On follow up 4-13 years after probing in childhood 30% of patients still had symptoms of epiphora or discharge. Surprisingly, a similar high symptom rate was found in the controls, such that there was no statistically s...

Dacryocystorhinostomy allows by-passing saccal and post-saccal stenoses and has traditionally been performed via an external approach, namely, external dacryocystorhinostomy. Over the past two decades, advances in endoscopic equipment have led to the widespread use of the endoscopic transnasal approach to the lacrimal pathway. A retrospective evaluation has been made of personal success rates i...

background and objectives: primary acquired nasolacrimal duct obstruction (pando) is a common ocular problem. clinical presentation can range from simple tearing to a life-threatening condition. the exact pathophysiology of obstruction is not completely understood. in this study, therelationship between pando and nasal mucosal goblet cells was investigated.  materials & methods: in this ca...

OBJECTIVE To determine the usefulness of "routine" lacrimal sac biopsy to evaluate unsuspected neoplasm or systemic disease in patients with acquired nasolacrimal duct obstruction. DESIGN Noncomparative, interventional case series with histopathologic correlation. PARTICIPANTS Review of charts revealed histopathologic reports on 302 specimens from 258 patients who had undergone routine dacr...
