A constantly watery or sticky eye in a baby is very common. Most often it is caused by a tear duct that has not fully opened—and, reassuringly, most improve naturally as your child grows.
Tears normally drain through tiny openings at the inner corners of the eyelids, into the tear sac and then down the nasolacrimal duct into the nose. In some babies, a thin membrane at the lower end of this duct has not opened completely at birth. Tears then collect or overflow, and mucus may cause the lashes to become sticky—particularly after sleep or during a cold.
This is called congenital nasolacrimal duct obstruction, often simply described as a blocked tear duct. It may affect one or both eyes and does not usually harm sight.
Most blocked tear ducts open as the drainage system develops. Around 8 in 10 have resolved by the first birthday in a large population-based study. Even among babies whose watering remained at 6–10 months, a PEDIG multicentre study found that 66% resolved without surgery during the following six months.
Improvement can continue during the second year of life. A prospective UK study of children whose obstruction had persisted into their second year found that 60% of the eyes observed without a procedure resolved before age two. Taken together, the evidence supports telling parents that around 9 in 10 or more affected children are likely to improve naturally by age two, although estimates vary between studies and a persistent blockage becomes less likely to clear as a child gets older.
Wash your hands, then gently wipe away tears or mucus with clean cotton wool or a soft pad moistened with clean water. Use a fresh pad for each wipe and a separate pad for each eye. Pat the surrounding skin dry.
A sticky eye does not automatically mean infection. If the white of the eye remains white and your child is otherwise well, antibiotic drops are generally not needed. They do not open the blocked duct. Seek advice if the eye itself becomes red or inflamed.
Do not massage a hot, tender or acutely swollen tear sac; seek urgent medical advice instead.
Dacryocystitis is a rare but potentially serious infection of the tear sac. Look for:
This needs urgent same-day assessment. Please contact your local NHS eye service or attend the appropriate local NHS urgent-care/A&E service. Do not wait for a routine private appointment. Do not perform Crigler massage over an acutely inflamed swelling.
A blocked tear duct is by far the more common cause of watering in a baby. Very rarely, however, persistent watering can be a sign of childhood glaucoma, in which pressure inside the eye is too high. Prompt diagnosis is important to protect sight.
Please seek an urgent assessment through your local NHS eye service if watering is accompanied by any of the following:
If the eye looks cloudy, enlarged or painful, or your baby is very light-sensitive, do not wait for a routine private appointment. Contact your local NHS eye department urgently or attend the appropriate NHS urgent-care/A&E service.
Watering with prominent itching, rubbing or redness may be caused by allergy or another form of eye irritation rather than a blocked tear duct. Read more about red eyes and eye allergies in children.
Although a blocked tear duct is the commonest explanation, watering is a symptom rather than a diagnosis. We assess your child in an age-appropriate, child-friendly way to:
You will leave with a clear explanation, practical home-care advice and an individual plan for review or referral.
If troublesome watering and discharge persist, a procedure to open the tear duct may be considered. The usual first procedure is probing and irrigation under a short general anaesthetic. Depending on the child’s age, symptoms, examination and whether the drainage pathway appears more complex, other techniques such as silicone intubation may sometimes be recommended.
Spire Southampton does not provide general anaesthesia for children under three years of age. If a procedure is needed below this age—or if your child is likely to need more specialised lacrimal treatment—we will advise on onward referral to an experienced paediatric lacrimal specialist in an appropriately equipped children’s hospital. This gives your child access to the most suitable expertise and aims to maximise the chance of success while minimising the need for repeat procedures.
For children aged three and over whose needs are suitable for Spire, we can discuss treatment within its dedicated paediatric surgical pathway, including paediatric anaesthetic and nursing care.
A child-friendly assessment can confirm the cause, check vision and provide a clear plan.
