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

Condition or disease Intervention/treatment
Lacrimal Apparatus Diseases Diagnostic Test: Probing /irrigation of lacrimal passages

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.

Group/Cohort Intervention/treatment
Adult patients suffering from watering of the eye included in the study to detect level of obstruction
Diagnostic Test: Probing /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.

Primary Outcome Measures :
  1. Level of obstruction of lacrimal system [ Time Frame: 3 years ]
    The level was detected either Punctal, Canalicular, Nasolacrimal duct or Mixed
