Tear Duct Obstruction Details
A blockage in the drainage system of the eye that prevents tears from draining normally.
Book ConsultationWhat is Tear Duct Obstruction?
Tear duct obstruction, also known as nasolacrimal duct obstruction or blocked tear duct, is a condition in which the drainage system for tears is partially or completely blocked. Tears normally drain from the eye surface through tiny openings in the eyelids (puncta), then through small canals into the lacrimal sac and down the nasolacrimal duct into the nose. When this pathway is blocked, tears cannot drain normally, causing watery eyes, irritation, and an increased risk of infection. Tear duct obstruction can affect people of all ages but is particularly common in newborns, affecting up to 20% of infants. In adults, it is often caused by age-related changes, infections, or nasal conditions.
Tear Duct Obstruction Symptoms
- Excessive tearing (epiphora) even when not crying
- Redness of the white part of the eye
- Recurrent eye infections or conjunctivitis
- Swelling and pain near the corner of the eye (lacrimal sac infection / dacryocystitis)
- Discharge of mucus or pus from the eye
- Crusting of the eyelids
- Blurred vision from excess tears
- A feeling of fullness or pressure near the eye
Tear Duct Obstruction Causes
- Congenital blockage — a thin membrane at the end of the tear duct that doesn't open at birth (common in infants)
- Age-related narrowing or closure of the tear duct
- Infections or chronic inflammation of the tear drainage system
- Nasal polyps or tumors obstructing the duct
- Facial injuries or trauma affecting the tear drainage pathway
- Previous nasal or sinus surgery
- Certain medications such as topical glaucoma eye drops
- Radiation therapy to the face
- Sarcoidosis or other granulomatous diseases
Treatment for Tear Duct Obstruction
- Massage of the lacrimal sac in infants (often resolves spontaneously by age 1)
- Warm compresses to relieve swelling and discomfort
- Antibiotic eye drops or ointments for infections
- Oral antibiotics for dacryocystitis (lacrimal sac infection)
- Probing of the tear duct — a thin wire is passed through the duct to open the blockage
- Balloon catheter dilation to widen a narrowed tear duct
- Intubation with silicone stents to keep the duct open
- Dacryocystorhinostomy (DCR) surgery to create a new drainage pathway into the nose
- Conjunctivodacryocystorhinostomy (CDCR) with Jones tube for severe blockages
When to See a Doctor
Consult an eye doctor if you have persistent watery eyes, recurrent eye infections, or swelling and tenderness near the inner corner of your eye. For infants, most blocked tear ducts clear on their own by 6-12 months of age. However, if tearing persists beyond the first year, or if there is significant discharge, redness, or swelling, the child should be evaluated by a pediatric ophthalmologist. Adults with symptoms of tear duct obstruction should seek evaluation, as treatment can provide significant relief and prevent recurrent infections.
