Squint Evaluation, Orthoptics & Treatment at Anand Eye Centre
Squint, also called strabismus, is a condition where both eyes do not look in the same direction. It may be present in children or adults, may occur constantly or intermittently, and may affect appearance, depth perception, binocular vision or cause double vision.
What is squint or strabismus?
Squint is a condition where the two eyes are not aligned together. One eye may turn inward, outward, upward or downward. It may affect one eye, alternate between both eyes, appear occasionally or remain constant.
Squint may be present from childhood or may develop later due to refractive error, muscle imbalance, nerve palsy, eye disease, injury, systemic illness or neurological causes. A detailed eye and orthoptic evaluation helps identify the type, cause and treatment pathway.
Inward turn
One eye may turn inward towards the nose. This is often called esotropia.
Outward turn
One eye may drift outward, especially during tiredness, daydreaming or distance viewing.
Vertical deviation
One eye may appear higher or lower than the other and may need detailed movement assessment.
Why early evaluation is important in children
Childhood squint should not be ignored. In some children, the eye only appears misaligned because of facial structure, known as pseudo-squint. In others, true squint may be present and can affect visual development.
A child with squint may need vision testing, glasses assessment, lazy eye evaluation, binocular vision testing and periodic follow-up. Early treatment can help reduce the risk of long-term visual weakness.
Some children are born with eye misalignment or develop it in early infancy.
Long-sightedness or uncorrected spectacle power can contribute to squint in some children.
If one eye is not used properly, amblyopia may develop and needs timely treatment.
Hereditary factors, childhood illness or nerve-related causes may need evaluation.
When should squint be checked?
Squint can be obvious, subtle or intermittent. Children may not always complain, so parents should watch for eye misalignment, closing one eye, abnormal head posture or poor visual attention.
Eye turning inward or outward
Visible eye deviation, even if occasional, should be evaluated.
Double vision
Adults or older children may report seeing two images, especially in sudden-onset squint.
Head tilt or face turn
Some children adjust head posture to compensate for eye alignment or movement problems.
Closing one eye
Closing one eye in sunlight or while focusing may suggest intermittent squint or double vision.
Poor depth perception
Difficulty judging distance may occur when both eyes are not working together properly.
Reduced vision in one eye
Squint may be associated with lazy eye, refractive error or other eye conditions.
How squint is assessed at Anand Eye Centre
Squint assessment is more than checking whether the eyes look straight. It includes measuring the deviation, checking vision in each eye, assessing eye movements and understanding whether both eyes work together.
History and symptom review
The doctor reviews age of onset, frequency, double vision, head posture, family history, previous glasses, trauma or neurological symptoms.
Vision and refraction assessment
Each eye is tested separately. Spectacle power is checked because refractive error can contribute to squint in some patients.
Orthoptic evaluation
Orthoptic tests help measure type and amount of squint, binocular vision, fusion, eye movement and fixation pattern.
Fundus and eye health check
The retina, optic nerve and overall eye health may be examined to rule out associated eye disease.

The treatment plan may include glasses, patching, exercises, prism, observation, surgery or referral depending on type and cause.
How can squint be treated?
Treatment depends on age, cause, vision in each eye, type of squint, amount of deviation, presence of lazy eye and whether double vision is present. Not every squint requires surgery, and not every squint can be managed with exercises alone.
Some squints improve when appropriate spectacle correction is prescribed and used regularly.
Patching or other amblyopia therapy may be advised in children where one eye is weaker.
Exercises may help selected eye coordination problems but are not suitable for every type of squint.
Surgery may be considered when alignment cannot be adequately corrected by non-surgical methods.
Treatment may be planned for:
- Improving eye alignment
- Reducing or managing double vision
- Supporting binocular vision development in children
- Treating lazy eye where possible
- Improving head posture where linked with squint
- Improving functional comfort and appearance
- Monitoring nerve-related or paralytic squint
What to know about squint surgery
Squint surgery adjusts the position or tension of eye muscles to improve alignment. It is an external eye muscle procedure and does not remove the eye from its socket. Suitability, timing and expected outcome depend on clinical findings.
Usually planned after measurement
The amount and type of squint are measured before deciding the surgical plan.
May need fine-tuning
Some large or complex squints may require more than one procedure or staged treatment.
Follow-up remains important
Eye redness, drops, review visits and healing instructions are part of the post-operative care plan.
Squint care connects with wider eye care
Squint may overlap with refractive error, lazy eye, neuro-ophthalmology, retina concerns, cataract in adults or general eye health. These related pages help patients understand the complete pathway.
Concerned about eye misalignment, lazy eye, double vision or childhood squint?
A structured squint and orthoptic evaluation can help identify the type, cause and appropriate treatment pathway. Early evaluation is especially important in children because vision development can be affected.
Helpful details to share
- When the squint was first noticed
- Whether it is constant or occasional
- Whether one eye turns inward, outward, upward or downward
- Any double vision, headache or eye movement restriction
- Previous glasses or patching history
- Old prescriptions, photos or eye reports if available
Frequently asked questions on squint and orthoptics
These answers are general and do not replace personal medical advice. The final treatment plan depends on clinical examination and orthoptic assessment.
Can squint be corrected at any age?
Many types of squint can be treated in children and adults, but the goal and expected outcome differ by age, duration, cause, lazy eye status and binocular vision development.
Is squint only a cosmetic problem?
No. Squint may affect binocular vision, depth perception, visual development in children and may cause double vision in adults. It can also be linked with eye or nerve-related conditions.
Can glasses correct squint?
In some children and adults, spectacle correction can reduce or control squint, especially when refractive error contributes to the deviation. Other cases may need additional treatment.
What is lazy eye or amblyopia?
Lazy eye is reduced vision in one eye due to abnormal visual development. It may occur with squint, unequal spectacle power or other causes and is usually treated more effectively when detected early.
Are eye exercises useful for squint?
Eye exercises may help selected binocular vision or convergence problems, but they cannot correct every type of squint. The doctor will advise whether exercises are suitable after evaluation.
Is squint surgery painful?
Squint surgery is generally performed with anaesthesia. Some redness, watering, foreign body sensation or discomfort may occur during recovery, and medicines are prescribed as advised by the doctor.
Will more than one squint surgery be needed?
Some patients, especially those with large, complex or long-standing squints, may require more than one procedure or staged correction. This is discussed during treatment planning.
When is adult squint urgent?
Sudden squint with double vision, headache, drooping eyelid, unequal pupils, weakness, vomiting or eye movement restriction should be evaluated promptly because nerve-related causes may need urgent attention.
