Blocked Tear Duct
A blocked tear duct is a blockage of the passage that drains tears from the eye into the nose, causing watering, crusting and infection. In adults it is mostly treated with DCR surgery; in babies with massage and, if needed, probing.
Tear Drainage and Symptoms
Tears are produced constantly, moisten the eye and drain through tiny openings (puncta) at the inner corner of the eyelids into the tear duct and on to the nose. When this passage is blocked you may notice:
- Constant watering
- Crusting or sticky discharge
- Swelling and infection at the inner corner of the eye
Treatment in Adults
- If the blockage is at the punctum, a minor procedure widens the opening.
- In most cases the blockage lies within bone, before the duct opens into the nose. Dacryocystorhinostomy (DCR) surgery then creates a new drainage route into the nose; a tube may be placed in the duct if needed.
Blocked Tear Ducts in Babies
Newborns can also have a blocked tear duct; most open on their own within the first year.
- Tear sac massage is done as shown by your doctor.
- If the blockage persists, probing is usually carried out at around 6–12 months or within the first year.
Frequently asked questions
Will my baby's blocked tear duct clear?
Most clear on their own within the first year. Massage as shown by your doctor helps; probing is done if it persists.
What is DCR surgery?
An operation that creates a new passage through the bone so tears can drain into the nose; it is commonly used for blockages in adults.
