Newborn Blocked Tear Duct: Tearing and Eye Discharge

What does the evidence say about blocked tear duct in a newborn?

1. The tear drainage pathway may be incompletely open at birth. Tears can overflow onto the cheek or dry into crusts. An eye examination helps distinguish a drainage problem from infection or another cause of watery eyes. 1
2. Routine newborn erythromycin ointment is directed at gonococcal eye infection. It does not establish that later discharge is harmless. Tell the clinician about new redness, swelling, or discharge even when the baby received prophylaxis at birth. 2
3. Birth eye ointment does not cover chlamydial neonatal eye infection. Maternal screening history and the timing and nature of symptoms can affect assessment. A blocked duct should not be assumed solely because an infant has a sticky eye. 3
4. A warm, wet cloth can gently remove accumulated crusts, and a clinician may recommend massage. Most infant blockages resolve during the first year, but persistent cases may need specialist assessment and a procedure to open the pathway. 1
5. A rectal temperature of 100.4°F (38°C) or higher in a newborn requires immediate medical evaluation. Fever, marked eyelid swelling, or an ill-appearing baby should not wait for a routine tear-duct appointment. 4

How should persistent newborn tearing be followed?

• At the first persistent eye symptoms, ask the pediatric clinician to assess the drainage and eye appearance.
• If conservative care is advised, use the demonstrated cleaning or massage method and monitor changes.
• For persistent blockage or any signs of infection, arrange reassessment and any recommended eye referral.
