Squint in adults

Adult squint, whether a childhood misalignment that has drifted or a new one from nerve or muscle problems, causes double vision or cosmetic concern, and surgery is effective at any age.

Key points

What matters most, at a glance.

The essentials in plain English - symptoms, when to seek help, who to see and what treatment looks like.

  • New-onset squint with double vision needs medical assessment to find the cause - it is never just cosmetic

  • Long-standing childhood squints can decompensate in adulthood, causing eye strain and intermittent doubling

  • Prisms in glasses manage many symptomatic squints without surgery

  • Squint surgery in adults is safe, effective and available on the NHS - correcting alignment is not merely cosmetic and improves function and wellbeing

  • Specialist: a consultant ophthalmologist with orthoptist support; botulinum toxin is an option for selected cases

Understanding it

About Squint in adults, and what to do next.

Adult misalignment has two broad origins: a controlled childhood squint that breaks through as fusional reserves tire with age, screens or illness, causing aching, intermittent doubling and difficulty concentrating; or a genuinely new deviation from nerve palsies, thyroid eye disease, myasthenia, trauma or sight loss in one eye, which demands a diagnostic work-up. In both, the misalignment also carries a social weight, eye contact matters, and its effect on confidence is well documented.

Orthoptic assessment quantifies the deviation; prisms, exercises for convergence problems, botulinum toxin or adjustable-suture surgery restore alignment, with high satisfaction rates in adults. The old advice that nothing can be done after childhood is simply wrong. Most people start with their GP, who can refer to a consultant ophthalmologist. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks depending on where you live, whereas an initial appointment with a private consultant is typically available within around two weeks.

    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 adults 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.

  • How long does squint in adults 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 adults?

    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 adults, 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.
