Involutional stenosis is probably the most common cause of nasolacrimal duct obstruction in older people. It affects women twice as frequently as men. Although the inciting event in this process is unknown, clinicopathologic study suggests that compression of the lumen of the nasolacrimal duct is caused by inflammatory infiltrates and edema.
When considering the possible causes for spontaneous NAION, the list includes other conditions like arteritic anterior ischemic optic neuropathy (associated with inflammation of arteries), optic neuritis (inflammation of the optic nerve), infiltrative and compressive types of optic neuropathy (where the optic nerve is invaded or pressed upon by ...
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture. During an ear infection, excess mucus may drain through the nasolacrimal duct in the opposite way tears drain. [citation needed] In humans, the tear ducts in males tend to be larger than the ones in ...
Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of the lacrimal sac. [1] The term derives from Greek dákryon 'tear' cysta 'sac' and -itis 'inflammation'. [2] It causes pain, redness, and swelling over the inner aspect of the lower eyelid and epiphora.
Canaliculodacryocystostomy is a surgical correction for a congenitally blocked tear duct in which the closed segment is excised and the open end is joined to the lacrimal sac. [33] [36] Canaliculotomy involves slitting of the lacrimal punctum and canaliculus for the relief of epiphora [33] A dacryoadenectomy is the surgical removal of a ...

In each eye, there are two puncta [59] – little openings that drain tears into the tear ducts. [4] There are methods to partially or completely close the tear ducts. [16] This blocks the flow of tears into the nose, and thus more tears are available to the eyes. [13] Drainage into either one or both puncta in each eye can be blocked.
