A watering infant can have a serious eye disorder
Photophobia with an enlarged or cloudy cornea suggests childhood glaucoma. A tender inflamed tear sac, spreading lid swelling or a newborn with respiratory difficulty requires urgent assessment.
Action: Arrange same-day ophthalmology or acute paediatric assessment according to the presentation; respiratory compromise needs immediate emergency care. Do not place these children on a routine tear-duct waiting pathway.
Synopsis
Distinguish common infant tear drainage delay from glaucoma, neonatal infection and an obstructing lacrimal cyst, and organise proportionate conservative care or specialist referral.
Tears normally reach the nose through the puncta, canaliculi, sac and nasolacrimal duct.
A persistent distal membrane can cause overflow and intermittent stickiness from early infancy.
Simple obstruction usually leaves the cornea clear and the conjunctiva relatively quiet.
Key red flags
Light avoidance, forceful lid closure or corneal enlargement accompanying epiphora.
Investigation priorities
01
General assessment and eye examinationFirst step
Determine whether observation is safe before assigning a drainage diagnosis.
Management branches
Conservative careA comfortable infant with simple drainage delay
Early watering and crusting occur without corneal, systemic or inflammatory warning signs.
Explain the likely drainage mechanism and expected spontaneous improvement during infancy.
Demonstrate clean lid care and a safe downward lacrimal massage technique away from the globe.
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 7 Sept 2026; clinical approval remains outstanding.
