Children diagnosed with a squint, or strabismus, typically require clinical reviews much more frequently than once a year, especially during the early stages of treatment. In the UK, the NHS follow-up schedule is determined by the severity of the eye misalignment, the child’s age, and whether a secondary lazy eye (amblyopia) has developed. Because a child’s visual system undergoes rapid changes during the first eight years of life, specialists must monitor eye alignment and visual acuity closely to ensure that treatments such as glasses or patching remain effective. While an annual check may be appropriate for some older children with stable conditions, most younger children are seen every few months to prevent permanent vision loss and to adjust their care plan as they grow.

Standard NHS Monitoring Intervals
For most children in the UK undergoing treatment for a squint, the initial follow-up interval is usually every three to four months. This frequency allows the orthoptist and optometrist to closely monitor how the child’s eyes are responding to intervention. If a child has been prescribed glasses to correct an inward turn, the specialist needs to check if the eyes are straightening as expected. Similarly, if a child is wearing a patch to treat a lazy eye, frequent reviews are necessary to measure improvements in visual acuity and to ensure the “good” eye is not being over-patched.
According to the NHS, children with a squint will need regular follow-up appointments at a hospital eye clinic to monitor their vision and eye alignment. These appointments are essential because a child’s eyes are still developing. If a treatment is not working as intended, a three-month review allows the clinical team to make timely adjustments, such as changing the strength of the glasses or increasing the number of hours the patch is worn. Waiting a full year between checks during this critical period could result in a missed opportunity to correct the vision effectively.
As the condition becomes more stable and the child’s vision reaches its full potential, the gap between appointments may gradually increase. However, the decision to extend the time between checks is always based on the individual child’s clinical progress. Even when a squint appears stable, regular reviews remain a priority to ensure that the eyes continue to work together and that no regression occurs.
Why Age Influences the Frequency of Checks
The age of the child is a primary factor in determining how often their eyes should be checked. The “critical period” for visual development lasts from birth until approximately age seven or eight. During this window, the brain is highly sensitive to the visual input it receives from the eyes. If a squint is present, the brain can very quickly learn to suppress the image from one eye, leading to a lazy eye. Because this process can happen rapidly in toddlers and pre-schoolers, they require more frequent monitoring than an older child whose visual pathways are more established.
In very young children, the refractive state of the eye (the need for glasses) can also change quickly as the eye grows in size. An infant might be significantly long-sighted one year and require a completely different prescription the next. Frequent optometric reviews ensure the child is always wearing the most accurate lenses to support their eye alignment. Once a child reaches the age of nine or ten, the visual system is less “plastic,” and while the squint still needs monitoring, the risk of developing a new lazy eye is significantly reduced.
Clinical guidelines from NICE emphasize that children in the early stages of visual development require more intensive monitoring of strabismus to prevent permanent amblyopia. For these younger patients, the orthoptist acts as a guardian of their long-term sight. By seeing the child frequently, the specialist can ensure that both eyes are being used and that the neurological connections between the eyes and the brain are strengthening correctly.
Adjusting Treatment Through Regular Reviews
Managing a squint is rarely a static process; it is a dynamic treatment that evolves as the child matures. Regular reviews allow the specialist to perform “cycloplegic refractions,” where eye drops are used to reveal the true focus of the eye. This is often done once a year, but the vision is checked at every visit. If the visual acuity in a lazy eye has stopped improving, the orthoptist might decide to change the patching schedule. Conversely, if the vision has reached a normal level, they may start “tapering” the patch to ensure the vision remains stable.
The physical alignment of the eyes can also change. A squint that was previously well-controlled by glasses might start to “break down,” meaning the eye begins to turn even when the child is wearing their spectacles. Regular orthoptic measurements using prisms allow the specialist to detect these subtle shifts. If the angle of the squint is increasing, it may indicate that a different approach, such as eye exercises or a discussion about surgery, is necessary.
These frequent checks also provide a vital opportunity for parental support. Following a patching or glasses routine can be challenging for families. Seeing the orthoptist every few months allows parents to discuss any difficulties they are facing and to receive updated advice on how to encourage their child. This ongoing relationship between the family and the clinical team is a cornerstone of successful squint management in the UK.
Monitoring During Growth and Development
As a child grows, the physical structure of their face and eye sockets changes, which can influence the appearance and severity of a squint. Growth spurts can sometimes affect the balance of the extraocular muscles or the way a child compensates for their misalignment. Regular monitoring ensures that any changes occurring as a result of natural growth are identified and managed. This is particularly important for children who have had squint surgery, as the eyes can sometimes shift slightly as the child gets older.
Furthermore, as children start school, the visual demands on their eyes increase significantly. They begin to spend more time on close-up tasks like reading and writing, which can place additional strain on the visual system. A child whose squint was manageable at home might struggle with the increased focus required in a classroom environment. Frequent reviews during these transition years allow the specialist to ensure the child has the visual comfort and clarity they need to succeed in their education.
NICE evidence suggests that long-term follow-up is necessary for children with strabismus to monitor for recurrence or changes in binocular status during childhood development. This longitudinal care ensures that the child does not “fall out” of the system just as their visual needs are changing. The goal of the NHS is to support the child through these developmental milestones until their vision is stable and they can be safely discharged to community optometry.
Transitioning to Less Frequent Reviews
Once a child’s squint is stable, their vision is equal in both eyes, and they have reached an age where their visual development is mostly complete, the specialist may suggest moving to less frequent reviews. This might mean seeing the orthoptist every six months or once a year. For some older children whose squint is purely cosmetic and whose vision is stable, they may eventually be discharged from the hospital service altogether.
At this stage, the child is often referred back to a high-street optometrist for their annual eye tests. The optometrist then takes over the role of monitoring the child’s vision and the health of their eyes. However, the optometrist will always have the option to refer the child back to the hospital eye department if they notice any changes in the squint or a drop in vision. This integrated approach ensures that the child remains within a safety net of professional care.
The decision to move to annual checks is a positive milestone in a child’s treatment journey. It indicates that the primary goals of treatment—improving vision and alignment—have been successfully met. Parents are encouraged to continue with these regular optician visits throughout the child’s teenage years to ensure that their eye health and prescription remain optimal as they enter adulthood.
Conclusion
Most children with a squint require eye checks more frequently than once a year, often every three to four months during the critical years of visual development. These regular NHS reviews are essential for adjusting treatments like patching and glasses and for monitoring eye alignment as the child grows. As the condition stabilises and the child gets older, the frequency of appointments may gradually reduce to an annual basis. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Why can’t my child just have an eye test once a year?
In the early years, vision can change rapidly; frequent checks ensure that treatments like patching are adjusted in time to be effective.
How long will my child need to keep going to the hospital eye clinic?
Most children are monitored until their vision is stable and they are around nine or ten years old, though some may be seen for longer.
What happens if we miss an appointment?
Missing an appointment can delay necessary changes to your child’s treatment, so it is important to reschedule as soon as possible.
Can an optician do the regular checks instead of the hospital?
While opticians check vision and focus, the specialist management of a squint is usually led by a hospital-based orthoptist.
Does my child need new glasses every time they are checked?
Not necessarily; the specialist will only change the prescription if the refractive state of the eye has changed significantly.
Will my child’s squint get worse if they aren’t checked often?
Without regular monitoring, a lazy eye could develop, or an existing squint could become less stable, making it harder to treat later.
Are these frequent hospital visits free?
Yes, all specialist eye care and follow-up appointments for children are provided free of charge by the NHS.
