Epiphora implies to overflowing of tears due to impairment lacrimal drainage.

OR due to a disruption in the balance between tear

production and tear loss.

17

Anatomical tests

These tests helps in localization of obstruction

Syringing / irrigation

Diagnostic probing

Dacryocystography

CT/MRI

18

Functional tests

To access functioning of lacrimal apparatus under physiologic conditions

Performed only when there is no evidence of obstruction in anatomical tests

Flourescein dye disappearance test Jones dye test (jones primary and secondary )

Canaliculi

Depends on the site and degree of obstruction

Intubation Anastomosis of the patent part of the

canaliculus into the lacrimal sac and intubation

24

Nasolacrimal duct

Massage of the lacrimal sac increases the hydrostatic pressure and may rupture membranous obstruction

Probing of the lacrimal system

25

Lacrimal surgery

Dacryocystorhinostomy (DCR) Indicated for obstruction beyond the medial

opening of the common canaliculus Anastomosing the lacrimal sac to the nasal mucosa

of the middle nasal meatus Procedure is performd under general hypotensive

anaesthesia

Conclusion

Diagnosis of the condition and ruling out the cause is important.

Treatment of the cause will depend on the cause of watering.

Optometrist should treat the causes to anterior segment disease.

Cases requiring surgery should be referred to ophthalmologist.

Cases of systemic disease should be referred to physician.
