What Is Squint & Pediatric?
Squint is a condition where the eyes do not align properly. One eye may turn in, out, up, or down, while the other eye looks straight ahead.
It can occur in one or both eyes and may be constant or intermittent.
Strabismus can result in double vision, difficulty with depth perception, and in some cases, amblyopia (commonly known as “lazy eye”), where the brain starts to ignore the misaligned eye.
The term Pediatric refers to the branch of medicine that deals with the care and treatment of children, from birth to adolescence.
Pediatric care includes not only general health, but also addressing specific childhood conditions, including pediatric strabismus or squint.
When we combine both terms, Pediatric Squint refers to the diagnosis and treatment of squint (strabismus) in children. Pediatric ophthalmologists are the specialists who treat these conditions in young patients.
Types of Squint & Pediatric
Here’s an overview of some of the most common Squint & Pediatric Type:
Esotropia
The eye turns inward.
Exotropia
The eye turns outward.
Hypertropia
The eye turns upward.
Hypotropia
The eye turns downward.
Causes of Squint & Pediatric
Squint (or strabismus) in children can arise from a variety of causes, ranging from genetic factors to neurological issues. When we talk about pediatric squint, we focus on the underlying causes and conditions that may affect a child’s eye alignment. Here are some of the primary causes:
Family history: A family history of squint or other eye disorders can increase the likelihood of a child developing strabismus.
Refractive Errors (Vision Problems): Children with uncorrected farsightedness may develop esotropia (inward turning of one or both eyes). Their eyes may cross as they strain to focus.
Neurological Disorders: Some children with cerebral palsy may develop strabismus as part of the neurological dysfunction that affects muscle control.
Congenital Strabismus: A type of squint that occurs at birth or in early infancy. This is often associated with a misalignment of the eyes, usually esotropia (eyes turning inward).
Muscle Weakness or Imbalance: If the muscles around the eyes are weak or fail to work together in a coordinated way, strabismus can occur.
Vision Loss or Amblyopia (Lazy Eye): In some children, strabismus can result from or lead to amblyopia (lazy eye), where the brain starts to ignore one of the eyes.
Symptoms of Squint & Pediatric
Prompt attention to these symptoms can help in the early treatment of strabismus, which can significantly improve the child’s quality of life and visual development.
- Misaligned eyes (inward, outward, up, or down).
- Intermittent or constant eye turning.
- Double vision or blurred vision.
- Head tilting or turning to compensate for eye misalignment.
- Squinting or closing one eye, especially in bright light.
- Difficulty judging depth or seeing in 3D.
- Frequent eye strain or complaints of tired eyes.
- Reduced vision in one eye (amblyopia).
- Clumsiness or difficulty with tasks requiring coordination.
Treatment
Corrective Lenses: If refractive errors like farsightedness are the cause, glasses or contact lenses may help to align the eyes.
Patching Therapy: If amblyopia is present, patching the stronger eye may encourage the brain to use the weaker, misaligned eye.
Vision Therapy: Eye exercises and other therapeutic measures can help strengthen the eye muscles and improve coordination between the two eyes.
Surgery: In more severe cases, surgery to realign the muscles of the eyes may be necessary.
Botox Injections: In certain cases, Botox injections may be used to temporarily paralyze an overactive eye muscle, which can help with alignment.

FAQs
How can I tell if my child has squint?
Symptoms of squint in children include:
- Eye misalignment: One or both eyes may appear turned in, out, up, or down.
- Head tilting: A child may tilt their head to focus or compensate for misalignment.
- Squinting or closing one eye: Especially in bright light.
- Complaints of double vision or difficulty with depth perception.
- Clumsiness or difficulty catching balls: Problems with judging distance.
At what age can squint be detected in children?
Squint can be detected as early as 2-3 months of age, especially in cases of congenital esotropia (inward eye turning). However, some types of squint may only become noticeable when the child is older (e.g., exotropia), often in preschool years.
How is squint diagnosed in children?
A pediatric ophthalmologist will:
- Conduct a comprehensive eye exam to check for misalignment.
- Perform tests such as the cover-uncover test to assess how the eyes work together.
- Screen for refractive errors like farsightedness (hyperopia) or astigmatism.
- Evaluate the eye muscles and nerve function.
- In some cases, imaging tests may be ordered if a neurological cause is suspected.
Can squint be treated?
Yes, squint can often be treated. Treatment options include:
- Corrective lenses: Glasses can address refractive errors that cause squint.
- Patching: If amblyopia is present, patching the stronger eye encourages the brain to use the weaker eye.
- Vision therapy: Exercises to improve eye muscle coordination and alignment.
- Surgery: In cases where other treatments do not work, surgery on the eye muscles may be necessary to correct the alignment.
- Botox injections: Used in some cases to temporarily weaken overactive eye muscles.
What is amblyopia (lazy eye), and how is it related to squint?
Amblyopia is a condition where one eye has reduced vision because the brain starts to ignore the signals from that eye, often due to strabismus. If left untreated, squint can lead to amblyopia, which can cause permanent vision loss in the affected eye. Early detection and treatment of squint are crucial to prevent amblyopia.
How can I prevent squint in my child?
While many causes of squint are genetic or congenital, there are some preventive steps:
- Regular eye exams: Early detection of refractive errors or misalignment can help prevent squint.
- Correct refractive errors: If your child has farsightedness or other vision issues, glasses may prevent strabismus.
- Avoiding eye strain: Encourage breaks from close-up work (reading, screen time) to reduce strain on the eyes.
- Ensuring proper prenatal and postnatal care: Reducing risks associated with prematurity or low birth weight.
Can squint go away on its own?
In some cases, especially with intermittent strabismus, the condition may improve as a child grows. However, most types of squint require treatment to fully resolve, particularly to prevent complications like amblyopia. Early intervention is key to successful treatment.
Is squint hereditary?
Yes, strabismus can run in families. If a parent or close relative has had squint, there may be a higher risk of it occurring in a child. However, squint can also occur in children with no family history of the condition.
Will my child need surgery for squint?
Surgery is usually a last resort if other treatments, like glasses or patching, don’t correct the misalignment. The surgery involves adjusting the muscles around the eye to improve alignment. However, not all children with squint will need surgery, and many cases are successfully managed with non-surgical treatments.
How long does treatment for squint take?
Treatment duration varies depending on the severity of the squint and the chosen method:
- Glasses: May be worn continuously and checked regularly for adjustments.
- Patching therapy: Often required for several hours a day over a few months or longer, depending on the child’s response.
- Vision therapy: Exercises are typically performed for weeks or months.
- Surgery: Recovery from eye muscle surgery usually takes a few weeks, though improvement in alignment can be immediate.
Can squint affect my child’s education?
Squint can affect a child’s vision, making activities like reading or writing difficult. Poor depth perception or double vision can also cause frustration in school tasks. Early treatment and corrective measures, such as glasses or vision therapy, can improve the child’s ability to perform academically.
How often should my child have eye exams if they have squint?
Children with squint should have regular eye exams to monitor the alignment of the eyes, particularly during treatment. Initially, visits may be more frequent (every 6-12 months), but once treatment is stable, exams may be spaced out. Follow-up visits are important to track the progress of vision therapy or post-surgery results.
What are the risks of untreated squint?
If left untreated, strabismus can lead to several complications, including:
- Amblyopia (lazy eye): Permanent vision loss in the misaligned eye.
- Double vision: If both eyes are not aligned, it can lead to difficulty focusing and seeing clearly.
- Social and emotional effects: Children with visible squint may experience teasing or self-esteem issues.
