Introduction
If nasolacrimal duct obstruction is accompanied by infection, it may cause pain in the nasolacrimal area. It may also present with increased local purulent discharge, and may be associated with abnormalities such as headache and decreased vision. After nasolacrimal duct obstruction, epiphora (excessive tearing) occurs, which can affect one or both eyes. Symptoms of epiphora may worsen under stimuli such as cold weather, dust, or wind.
The symptoms of nasolacrimal duct obstruction typically include pain, purulent discharge, and epiphora.
1. Pain
If nasolacrimal duct obstruction is complicated by infection, it may cause pain in the area of the nasolacrimal duct.
2. Purulent Discharge
After nasolacrimal duct obstruction, a mixture of pus and tears may be discharged, resulting in increased local purulent secretions—such as yellowish, sticky eye discharge—leading to crusting of the eyelashes. This commonly occurs when infection is present and may be accompanied by other abnormalities such as headache and decreased vision.
3. Epiphora
When the nasolacrimal duct is obstructed, tears cannot drain properly through the tear ducts and instead overflow from the eyelids, causing excessive tearing. The eyes may constantly appear watery, and as the condition progresses, this can develop into persistent epiphora, affecting one or both eyes. Symptoms may worsen under stimuli such as cold weather, smoke, dust, or wind.
If left untreated, nasolacrimal duct obstruction may lead to complications such as lower eyelid ectropion, dacryocystitis, and canaliculitis.
