2. Nasolacrimal duct obstruction - Wikipedia

   en.wikipedia.org/wiki/Nasolacrimal_duct_obstruction

   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. [7]

3. Nasolacrimal duct - Wikipedia

   en.wikipedia.org/wiki/Nasolacrimal_duct

   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 ...

4. Schirmer's test - Wikipedia

   en.wikipedia.org/wiki/Schirmer's_test

   Schirmer test = 0,00 in Sjögren's syndrome. The test works by the principle of capillary action, which allows the water in tears to travel along the length of a paper test strip in an identical fashion as a horizontal capillary tube. The rate of travel along the test strip is proportional to the rate of tear production.

5. Dacryoscintigraphy - Wikipedia

   en.wikipedia.org/wiki/Dacryoscintigraphy

   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 nasolacrimal ...

6. Oculoplastics - Wikipedia

   en.wikipedia.org/wiki/Oculoplastics

   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. [8] [10]

7. Epiphora (medicine) - Wikipedia

   en.wikipedia.org/wiki/Epiphora_(medicine)

   Causes of epiphora are any that cause either overproduction of tears or decreased drainage of tears, resulting in tearing onto the cheek. [2] This can be due to ocular irritation and inflammation (including trichiasis and entropion) or an obstructed tear outflow tract, which is divided according to its anatomical location (i.e., ectropion, punctal, canalicular or nasolacrimal duct obstruction).

8. Oculoplasty - Wikipedia

   en.wikipedia.org/wiki/Oculoplasty

   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 ...

   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 ...
