Brief summary

Detect anatomical level of acquired lacrimal passage obstructions among patients with epiphora. They were evaluated and divided into four groups Punctal, Canalicular, Nasolacrimal duct and Mixed groups according to level of obstruction

Detailed description

In a 3 years period adult patients with obstructive epiphora were evaluated clinically by Probing /irrigation of lacrimal passages to detect anatomical level of obstruction. The main site of obstruction was the common canaliculus where 2/3 of patients had canalicular problems. The second common site of obstruction is nasolacrimal duct followed by the puncti.

Interventions

DIAGNOSTIC_TESTProbing /irrigation of lacrimal passages

Probing of the lacrimal passage was done using #00 Bowman's lacrimal probe which can reveal any narrowing (resistance) or obstruction (soft stop) of the canaliculi during its advancement from punctum towards the lacrimal sac.
