duct obstruction--Also referred to as dacryostenosis.
Clinical and histological effects of the temporary occlusion of the rabbit nasolacrimal
duct and point using cyanoacrylate adhesives.
* Outflow dysfunction (obstructive) due to nasolacrimal
duct, punctal, or rarely, canalicular stenosis
Furthermore overzealous removal of the bone anterior to the natural ostium may result in injury nasolacrimal
duct or more superior extension accounts for a high rate of orbital complications.
In this study, we aimed to assess the etiologies of proximal nasolacrimal
system obstruction and compare the results of conjunctivodacryocystorhinostomy (CDCR) and/or conjunctivorhinostomy (CR) performed by two different tear drainage tubes, thereby assessing the relative advantages and disadvantages of each tear drainage tube, postoperative problems, and solutions thereof.

No inferior turbinate involvement or nasolacrimal
duct extension was present.
Exematous keratoconjunctivitis was found in 17 patients (22.08%), 19 (24.67%) having chronic allergic rhinitis with transient nasolacrimal
duct obstruction due to allergic edema.
duct obstruction (NLDO) is the most common lacrimal abnormality in infants and children, occurring in 2% to 30% of newborns, most commonly secondary to incomplete canalization of the distal nasolacrimal
duct, specifically the valve of Hasner.
Under the new procedure, one drop each of Cyclopentolate and Phenylephrine is instilled into both eyes of the baby and pressure is applied to the tear duct for one minute following instillation, minimising absorption of the medication through the nasolacrimal
