Blocked Nasolacrimal Duct

A blocked nasolacrimal duct is the blockage of the small canal that drains tears from the eye into the nose. When that duct becomes clogged, tears do not flow normally and build up.

Common symptoms:

• Excessive and constant tearing
• Discharge or crusting, especially upon waking
• Redness or irritation at the inner corner of the eye

Common causes: It may be present from birth in babies, or appear in adults due to inflammation, infections, or age-related changes.

Which specialist treats it? The ophthalmologist is the one who evaluates the tear duct and guides management; in young children, the first visit may be with the pediatrician or the general practitioner. If tearing or discharge persists, it is advisable to have it reviewed by an eye care professional.
