Tear-duct blockage occurs when the small ducts responsible for draining tears from the eyes become obstructed, preventing tears from draining properly. This can lead to symptoms like watery eyes, frequent eye infections, or a constant feeling of discomfort in the eyes. The blockage can be congenital (present at birth) or develop later in life due to conditions like infections, injury, or aging. Treatment may involve massages, medications, or, in some cases, surgical procedures to clear the duct and restore normal tear drainage. Early intervention can help prevent recurring infections and improve comfort.
What Is a Tear-Duct Blockage?
A tear duct blockage occurs when the small tube that drains tears from the eyes becomes blocked, preventing tears from draining properly. Tears are made by glands under the eyelids to keep the eyes moist and clean, but when the duct is blocked, tears can’t flow out as they should. Many babies are born with this condition, and it often resolves on its own by the time they turn 1 year old.
Signs & Symptoms of a Tear-Duct Blockage: A child with a blocked tear duct may show:
- Excessive tearing, even without crying
- Crusting on the eyelashes
- Mild redness or irritation around the eyes
An infection can develop in a blocked duct, causing symptoms like:
- Yellow or green discharge
- Redness of the eye
- Swollen eyelids
Causes of Tear-Duct Blockages: In babies, a tear-duct blockage is usually due to underdeveloped tear ducts, which may be too narrow or blocked by tissue. Older children can develop blockages from nasal polyps, cysts, tumors, or injuries.
Diagnosis & Treatment: A doctor will perform an exam and may use a dye test to check tear drainage. Blocked ducts often clear on their own, especially in babies younger than 6 months. Doctors may recommend gentle massage to help open the blockage. If the blockage persists or infections occur, an ophthalmologist can perform procedures like probing the duct, placing tiny tubes, or using a balloon catheter to open the duct.
How Parents Can Help: If you notice excessive tearing or signs of infection, contact your child’s doctor for guidance.
