A silastic tube or stent may be employed along with probing to maintain tear duct patency. [6] A systematic review comparing immediate probing with deferred probing found that in children with unilateral nasolacrimal duct obstruction, immediate probing resulted in a higher success rate of treatment compared to deferred probing.

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 ...
External or Endoscopic Dacryocystorhinostomy (DCR) for nasolacrimal duct obstruction [9]; Canalicular trauma (canalicular laceration) repair; 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.
Tear Duct Surgery: When tear ducts are blocked or damaged, it can cause chronic tearing or infections. Tear duct surgery, such as dacryocystorhinostomy (DCR), aims to create a new drainage pathway for tears to alleviate these issues. Orbital Surgery: Orbital surgery deals with problems within the eye socket, or orbit. This can include the ...
DSG allows quantification of tear turnover and drainage. [4] Various quantification models have been developed, which must account for the variable drainage of asymptomatic systems. [ 5 ] Some drugs administered to the eye via eye drops , such as beta blockers for glaucoma , can be hazardous if quickly drained and absorbed through the ...
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 ...
Dacryocystorhinostomy (DCR) is a surgical procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function. [ 1 ] Process
