Newborn and infant eyes worry parents. The eyes do not always appear perfectly aligned. The whites of the eye sometimes turn red. The eyes water and become sticky. None of these are necessarily abnormal, but distinguishing what can be observed from a distance from what requires prompt professional attention matters.
The stakes are higher in early infancy than in older children: some eye conditions that are easily treated if caught early become significantly harder to treat once the visual system has had months to develop around the abnormality.
Healthbooq (healthbooq.com) covers newborn and infant health through the early months.
Normal Findings
Subconjunctival haemorrhage is a bloodshot area in the white of the eye, bright red and sometimes looking alarming. It is caused by small vessels breaking during the pressure of delivery. It is painless, does not affect vision, and resolves within one to three weeks without treatment.
Intermittent eye crossing (intermittent esotropia or exotropia) is common in the first three months. The visual system is immature and the eyes are not yet reliably coordinated. Occasional crossing or wandering of one eye during the first weeks of life is normal. By three to four months, the eyes should be consistently aligned when the baby is looking at something.
Watery or sticky eyes in the first months of life are very commonly caused by nasolacrimal duct obstruction: a blocked or narrow tear duct that prevents tears from draining properly into the nose. Tears overflow and become sticky, sometimes forming a film over the eye. Treatment involves cleaning the eye with cooled boiled water and gentle massage of the inner corner (over the duct). Most blocked ducts open spontaneously by twelve months. If they do not, a minor procedure (probing) to open the duct can be done, usually around twelve to eighteen months.
Findings That Need Assessment
A white or cloudy appearance in the pupil (leukocoria) is the most urgent finding in an infant's eye. It may indicate congenital cataract (a clouding of the lens), retinoblastoma (a rare but serious eye tumour), or other serious conditions. It is the reason the red reflex is checked at the newborn examination: in a healthy eye with clear media, the pupil appears red-orange in a photograph or when light shines in it (like the red-eye effect in photos). A white or absent red reflex requires same-day ophthalmology referral.
Parents may notice an unusual reflection in a baby's eye in photographs. A white or bright reflection from the pupil rather than a red one in a photograph is worth seeking urgent medical assessment for.
Persistent squint: if one or both eyes are consistently turned in or out beyond three to four months of age, assessment by an ophthalmologist is needed. Squints do not go away on their own after this age and can lead to amblyopia (lazy eye), in which the brain suppresses input from the misaligned eye and it loses visual acuity. Early treatment (glasses, patching, occasionally surgery) prevents this.
Nystagmus: rhythmic, repetitive involuntary eye movements (jelly-like movements of the eyes). This is not normal at any age and requires ophthalmology assessment.
A very red, painful eye with discharge in a newborn requires same-day assessment as it may represent neonatal conjunctivitis from gonorrhoea or chlamydia, which can damage vision if not treated promptly.
The Newborn Eye Examination
At the routine newborn examination within the first 72 hours, and at the six-to-eight-week check, the examining clinician checks the red reflex, looks for signs of congenital eye conditions, and assesses eye movements. This is a brief but important screening step.
Parents who notice any unusual appearance in a baby's or infant's eyes between scheduled checks should contact their GP or health visitor rather than waiting for the next routine appointment.
Key Takeaways
Several eye findings in newborns and young infants are entirely normal and do not need treatment. Intermittent eye crossing in the first three months, subconjunctival haemorrhage (red blood visible in the white of the eye) from birth, and nasolacrimal duct obstruction (blocked tear duct) causing watery or sticky eyes are all common and usually resolve without intervention. A persistent squint (present all the time, or still present after three to four months), a white or cloudy appearance in the pupil, nystagmus (jelly-like eye movements), or a very red painful eye with discharge in a newborn all need urgent assessment. The newborn eye examination at the first check screens for serious conditions including cataracts and retinoblastoma.
