Health condition
Squint in children
A squint - one eye turning in, out, up or down - affects a small but significant number of children, and early treatment matters: the developing brain switches off the wandering eye, and the window to restore vision (treating amblyopia) closes in childhood.

Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Any constant squint, or any squint persisting after 3 months of age, needs referral - babies' eyes may drift occasionally in the first weeks, but a fixed turn is never normal
-
The urgency is amblyopia: the brain suppresses the squinting eye, and untreated, that eye's vision is permanently reduced
-
Treatment involves glasses (long-sightedness commonly drives squints), patching the stronger eye to force the weaker one to work, and surgery to realign the eyes where needed
-
Specialist: a consultant paediatric ophthalmologist with an orthoptist team; a newly noticed squint should also always have the red reflex checked
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
Children do not grow out of true squints, and the stakes are higher than cosmetic: when the two eyes point in different directions, the child's brain - unlike an adult's - simply suppresses the image from the deviating eye to avoid double vision, and vision in that eye stops developing. This is amblyopia, and the younger the child, the faster it sets in and the better it responds to treatment; left until later childhood, the vision loss becomes permanent. Hence the rule: any constant eye turn, at any age, and any intermittent turn persisting beyond three months, warrants referral.
Diagnosis and treatment routes
Assessment by the orthoptic and ophthalmology team measures the turn, tests vision in each eye separately, examines the eye's interior to exclude rare but critical causes (a white pupil reflex is an emergency referral), and checks for the long-sightedness that drives many childhood squints. Treatment is layered: glasses alone straighten a proportion of squints; patching or atropine drops for the stronger eye rebuild vision in the weaker; and squint surgery on the eye muscles realigns the eyes where a turn persists - delivering the best results for binocular vision when the whole pathway starts early. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant paediatric ophthalmologist and orthoptist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.

Frequently asked
Common questions about Squint in children.
Quick, plain-English answers to what people ask us most.
-
What does squint in children mean?
Squint in children is a medical condition that can affect people differently depending on severity, underlying cause and overall health. A clinician can confirm the diagnosis and explain what it means specifically for you.
-
What are the risk factors for squint in children?
Causes vary and can include genetic, environmental, lifestyle and other health-related factors, and in some people no single clear cause is found. Your clinician can help identify anything relevant to your own case.
-
What are the symptoms of squint in children?
Symptoms vary between individuals and depend on which body systems are affected and how significant the underlying problem is. Keeping track of what you notice, and when, helps your clinician assess it accurately.
-
Is squint in children serious or dangerous?
Severity varies from mild and self-limiting to more significant, depending on the underlying cause and how it's managed. A clinical assessment is the best way to understand what it means in your specific situation.
-
Is squint in children hereditary or genetic?
This depends on the specific condition — some cases have a genetic or familial component, while others are linked more to environmental, lifestyle or other health factors. If you have a relevant family history, it's worth mentioning to your clinician.
-
Can squint in children be cured, reversed or prevented?
Many cases can be effectively treated or managed, and prevention strategies exist for some causes, though this depends on the specific underlying reason in your case. Your clinician can explain what's realistic for you.
-
What treatment options are available for squint in children?
Treatment is tailored to the underlying cause and severity, and can range from simple lifestyle or self-management measures to medical or specialist intervention.
-
How long does squint in children last, or take to recover from?
This varies depending on the underlying cause, how early it's identified, and how well it responds to treatment — your clinician can give a more specific expectation once assessed.
-
When should specialist referral be considered for squint in children?
Specialist referral is worth considering if symptoms persist, are getting worse, or aren't responding to initial treatment — your GP can help decide the right pathway and urgency.
-
When should I see a doctor about squint in children, and how quickly can I be seen privately?
See a doctor if symptoms are persistent, worsening, or affecting your daily life — earlier assessment generally leads to better management. NHS routine referrals for this kind of concern often take 20–45 weeks or longer depending on the area, while a private consultant can typically see you within about 2 weeks, with faster access to scans and specialist opinion.
