Strabismus, commonly known as crossed eyes or squint eyes, is an eye condition in which both eyes do not align properly when looking at an object. One eye may look straight ahead while the other turns inward, outward, upward, or downward.
This condition can affect children and adults. In some cases, strabismus is present from early childhood, while in others, it develops later due to medical conditions, nerve problems, or changes in eye muscle control.
If you are searching for the best treatment for strabismus in India, understanding the underlying cause is essential.
Modern ophthalmology offers several treatment options, including prescription glasses, prism lenses, selected orthoptic exercises, botulinum toxin injections, and eye muscle surgery.
Nayan Vision, an ophthalmic pharmaceutical division of Arlak Biotech Pvt. Ltd., shares this educational guide to the causes, symptoms, diagnosis, and available treatments for crossed eyes.
What Is Strabismus?
Strabismus occurs when the eyes point in different directions instead of working together to focus on the same object.
Normally, the eye muscles coordinate to keep both eyes aligned. When this coordination is disrupted, one eye may turn away from the intended direction of gaze.
Strabismus may be constant or intermittent and can affect either eye or alternate between both eyes.
Types of Strabismus
Type | Eye Alignment |
|---|---|
Esotropia | Eye turns inward |
Exotropia | Eye turns outward |
Hypertropia | Eye turns upward |
Hypotropia | Eye turns downward |
Intermittent strabismus | Misalignment occurs only at certain times |
Alternating strabismus | Either eye may become misaligned |
In children, untreated strabismus can sometimes contribute to amblyopia, commonly called lazy eye.
Common Causes of Strabismus
Several factors may contribute to crossed eyes.
1. Eye Muscle Coordination Problems
Strabismus may occur when the muscles responsible for eye movement do not work together properly.
2. Refractive Errors
Significant farsightedness can contribute to accommodative esotropia, particularly in children.
Appropriate prescription glasses may improve alignment in these cases.
3. Family History
Children with a family history of strabismus may have an increased likelihood of developing the condition.
4. Neurological Conditions
Certain nerve disorders, strokes, and neurological diseases can affect the muscles controlling eye movement.
5. Eye Injuries
Trauma involving the eye socket, muscles, or nerves may lead to eye misalignment.
6. Reduced Vision in One Eye
Poor vision caused by certain eye conditions may interfere with normal binocular alignment.
Important: Newly developed strabismus in an adult, particularly with double vision, headache, or neurological symptoms, requires prompt medical evaluation.
Symptoms of Strabismus
The symptoms depend on age, severity, and type of misalignment.
Common signs include:
One eye turning inward or outward
Eyes appearing to look in different directions
Double vision
Difficulty judging depth
Eye strain
Closing one eye in bright sunlight
Head tilting or turning to see clearly
Difficulty focusing during reading
Young children may not complain of double vision because the brain can suppress the image from the misaligned eye.
Therefore, parents should not ignore visible eye misalignment.
Best Treatment for Strabismus in India
The most effective treatment depends on the patient’s age, the type of strabismus, the underlying cause, and whether amblyopia or double vision is present.
The following are commonly used treatment approaches.
1. Prescription Eyeglasses
Prescription glasses are an important treatment for certain types of strabismus associated with refractive errors.
For example, children with accommodative esotropia may experience inward eye turning because of excessive focusing effort.
Correcting farsightedness can reduce this effort and improve eye alignment.
Benefits
Non-surgical treatment
Corrects associated refractive errors
May improve alignment in suitable cases
Supports clearer vision
However, glasses do not correct every type of strabismus.
2. Prism Glasses
Prism lenses alter the direction of light entering the eyes.
They may help reduce double vision in selected patients with relatively small or stable deviations.
Benefits
Non-surgical option
Can improve visual comfort
May reduce double vision
Useful for certain adult patients
Prisms do not necessarily straighten the eyes or treat the underlying cause of misalignment.
An ophthalmologist or qualified eye-care specialist determines whether they are appropriate.
3. Eye Patching for Associated Amblyopia
Patching is commonly used to treat amblyopia when one eye has reduced vision.
During patching treatment, the stronger eye is covered for a prescribed period to encourage the brain to use the weaker eye.
Benefits
Helps improve vision in the amblyopic eye
Particularly useful during childhood
May be combined with glasses or other treatments
Important: Patching treats amblyopia rather than directly correcting eye alignment.
The treatment schedule should be determined by a pediatric ophthalmologist.
4. Atropine Penalization for Amblyopia
Atropine eye drops may be prescribed in selected children with amblyopia.
They temporarily blur near vision in the stronger eye, encouraging greater use of the weaker eye.
Benefits
Alternative to patching for selected patients
May improve vision in the amblyopic eye
Can be useful when patching is difficult
Atropine penalization is not a general treatment for crossed eyes and does not reliably straighten misaligned eyes.
It requires professional supervision.
5. Orthoptic Exercises and Vision Therapy
Specific eye exercises may help certain binocular vision disorders.
For example, supervised convergence exercises can be effective for symptomatic convergence insufficiency.
However, exercises do not correct every form of strabismus.
Potential Benefits
May improve convergence in suitable patients
Can reduce selected near-work symptoms
Supports binocular coordination for specific diagnoses
Patients should avoid relying on unverified online exercises as a substitute for professional treatment.
6. Botulinum Toxin Injections
Botulinum toxin may be injected into selected eye muscles to temporarily weaken their action.
This can change eye alignment and may be considered for particular types of strabismus.
Potential Benefits
Less invasive than conventional eye muscle surgery
May help selected patients
Sometimes used as an alternative or adjunct to surgery
The effects can be temporary, and repeat treatment may be required.
Possible complications include temporary eyelid drooping or unwanted changes in eye alignment.
7. Strabismus Surgery
Strabismus surgery is an established treatment for eye misalignment.
During surgery, an ophthalmologist adjusts the position or tension of one or more eye muscles to improve alignment.
When Is Surgery Recommended?
Surgery may be considered when:
Eye misalignment is significant
Glasses do not adequately correct alignment
Double vision affects daily activities
Abnormal head posture develops
Alignment affects binocular visual function
Benefits
Can improve eye alignment
May reduce double vision in selected patients
May improve head posture
Can support binocular function in suitable cases
Some patients require more than one procedure, and surgery does not guarantee perfect alignment or normal binocular vision.
8. Treatment of Underlying Medical Conditions
When strabismus develops because of a neurological disorder, injury, thyroid eye disease, or another medical condition, treatment must address the underlying cause.
Management may involve ophthalmologists, neurologists, endocrinologists, or other specialists.
Correct diagnosis is especially important when eye misalignment begins suddenly in adulthood.
Comparison of Strabismus Treatment Options
Treatment | Best Suited For | Important Considerations |
|---|---|---|
Prescription glasses | Refractive or accommodative strabismus | Effective only for suitable types |
Prism glasses | Selected cases with double vision | May not correct the underlying deviation |
Eye patching | Associated amblyopia | Improves vision, not alignment directly |
Atropine penalization | Selected childhood amblyopia | Requires prescription and monitoring |
Orthoptic exercises | Specific binocular vision disorders | Not suitable for all strabismus |
Botulinum toxin | Selected muscle deviations | Effects may be temporary |
Strabismus surgery | Persistent or significant misalignment | May require additional procedures |
Underlying-condition treatment | Secondary strabismus | Depends on the cause |
Is Strabismus the Same as Lazy Eye?
Strabismus and amblyopia are related but different conditions.
Feature | Strabismus | Amblyopia |
|---|---|---|
Meaning | Misalignment of the eyes | Reduced vision due to abnormal visual development |
Main Problem | Eyes point in different directions | One eye, or occasionally both, develops reduced visual acuity |
Can Occur Together? | Yes | Yes |
Common Treatments | Glasses, prisms, surgery, selected exercises | Glasses, patching, atropine penalization |
Not every child with strabismus develops amblyopia, and amblyopia can occur without visible eye misalignment.

Can Eye Drops Cure Strabismus?
A common question is whether eye drops can straighten crossed eyes.
There is no standard eye drop that directly corrects most forms of strabismus.
Eye drops may be used for associated conditions or specific treatment purposes.
For example:
Atropine may be prescribed for selected cases of childhood amblyopia.
Lubricating eye drops may relieve dry-eye symptoms.
Prescription medicines may treat certain accompanying eye conditions.
However, lubricating, antibiotic, or anti-allergic eye drops do not correct eye muscle alignment.

How Is Strabismus Diagnosed?
An ophthalmologist evaluates eye alignment, visual development, and eye movement.
The examination may include:
Visual acuity testing
Refraction to identify spectacle power
Cover and alternate-cover tests
Eye movement assessment
Binocular vision testing
Examination of eye structures
Additional investigations when a neurological cause is suspected
Children may require a dilated examination and cycloplegic refraction to accurately identify refractive errors.
Can Strabismus Be Treated in Adults?
Yes. Strabismus treatment is not limited to children.
Adults may benefit from prism glasses, selected exercises, botulinum toxin, surgery, or treatment of an underlying condition.
The appropriate approach depends on the type and duration of misalignment, symptoms, and overall eye health.
Although earlier treatment is important for childhood visual development, adults can still experience meaningful improvements in alignment and visual comfort.
When Should Parents Consult an Ophthalmologist?
Parents should arrange an eye examination if a child:
Frequently appears cross-eyed
Tilts or turns their head to focus
Closes one eye while looking at objects
Has difficulty tracking objects
Shows signs of reduced vision
Develops persistent or intermittent eye misalignment
Persistent crossing after early infancy should not be assumed to be normal.
Early assessment helps identify conditions that could interfere with visual development.
