About this study

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.

  • Acquired lacrimal obstructions
  • Adult patients with

Exclusion criteria

  • No previous lacrimal surgery
  • Congenital lacrimal obstructions

Treatment and study plan

Probing /irrigation of lacrimal passages

Diagnostic Test

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.

Primary outcomes
