Squint Eye Meaning, Causes, Treatment, Surgery

Squint Eye (Strabismus): What is It?

Strabismus, also known as crossed eyes or squint eyes, is a vision disorder that affects a person's ability to align both eyes simultaneously. When someone has strabismus, their eyes do not work together and are misaligned. One eye may look straight ahead while the other eye gets turned inward, outward, upward, or downward. It results in a loss of depth perception and can cause double vision.

Strabismus[1] can occur in one or both eyes and be constant or intermittent. There are different types of strabismus; they depend on the direction in which the eyes are misaligned. For example, esotropia happens when one eye turns inward, while exotropia occurs when one eye turns outward. Hypertropia occurs when one eye turns upward, and hypotropia occurs when one eye turns downward.

While strabismus can develop at any age, it often occurs in infants and young children. If left untreated, strabismus can lead to amblyopia, also known as lazy eye, which can cause permanent vision loss in the affected eye.

Squint Eye (Strabismus): Types

There are different types[2] of strabismus; they depend on the direction in which the eyes are misaligned. Some common types of strabismus include:

Esotropia: inward turning of one or both eyes
Exotropia: outward turning of one or both eyes
Hypertropia: upward turning of one or both eyes
Alternating strabismus: alternating between one eye turning in and the other turning out
Congenital strabismus: present at birth

Strabismus can also be classified based on the frequency and duration of the misalignment. Intermittent strabismus occurs when the eyes are misaligned only some of the time, while constant strabismus occurs when the misalignment is present all the time.

Squint Eye (Strabismus): Symptoms

The symptoms[1] of strabismus can vary depending on the type and severity of the misalignment. Some common symptoms include:

Misaligned eyes
Double vision
Poor depth perception
Eye strain or discomfort
Headaches
Squinting or closing one eye
Tilting the head to one side
Difficulty with tasks that require visual concentration, such as reading or driving

Symptoms may present continuously or only occur during certain activities or times of the day. If you experience any of these symptoms, see an eye doctor for a comprehensive eye exam immediately.

Squint Eye (Strabismus): Causes

Determining the underlying cause[2] of strabismus can help treat and manage the condition properly. Here is a more detailed list of the different causes of strabismus:

Problems with the muscles that control eye movement: Strabismus can occur when the muscles that control eye movement are not working well. It can be due to issues with the muscles or the nerves that control them.
Nerve abnormalities that affect eye movement: Strabismus can also occur due to abnormalities in the nerves that control eye movement. It can be due to conditions such as multiple sclerosis or brain tumors.
Refractive errors: Refractive errors such as nearsightedness, farsightedness, or astigmatism can cause the eyes to become misaligned.
Genetics or family history: Strabismus can run in families, and a genetic component to the condition can be present.
Brain injuries or neurological conditions: Traumatic brain injuries, strokes, and other neurological problems can affect the muscles or nerves that control eye movement and lead to strabismus.
Medical conditions: Certain conditions, such as diabetes, thyroid disease, or myasthenia gravis, can cause strabismus.
Medications: Some medications can affect the muscles or nerves that control eye movement, leading to strabismus.
Prolonged or untreated amblyopia: Amblyopia, also known as "lazy eye," is a condition where one eye has reduced visual acuity. If left untreated, amblyopia can lead to strabismus as the brain tries to compensate for the weaker eye.

Squint Eye (Strabismus): Diagnosis & Test

Here are some diagnostic tests[3] that your doctor may perform for squint eyes or strabismus:

Comprehensive eye exam: An eye doctor will perform a complete eye exam to check for any eye abnormalities or vision.
Cover/uncover test: This involves covering one eye at a time while the person looks at a target. The doctor will observe the uncovered eye to see if it moves to take over fixation from the covered eye.
Alternate cover test: This test is similar to the cover/uncover test but involves quickly switching the cover between the eyes to see how they move with each other.
Prisms and lenses test: This test involves using prisms and lenses to determine the amount and direction of any eye misalignment.
Visual acuity test: This test measures how well a person can see letters or objects at a distance.
Refraction test: This test measures the amount of refractive error, such as nearsightedness, farsightedness, or astigmatism, that a person has.
Eye movement test: This test evaluates the range and quality of eye movements and can help identify any muscle weakness or nerve problems.
Medical history and physical examination: The doctor may ask about the person's medical history and perform a physical exam to check for any underlying conditions causing the strabismus.

Based on the results of these tests, the doctor can diagnose the type and severity of strabismus and develop a treatment plan.

Squint Eye (Strabismus): Treatment & Surgery

The treatment[1] of strabismus, also known as squint eyes, can vary depending on the type and severity of the condition. Treatments can include eyeglasses or contact lenses, eye exercises, prism lenses, Botox injections, vision therapy, and surgery. It's crucial to consult with an experienced eye doctor to determine the most appropriate treatment plan. Here are some treatment options[2] for squint eyes or strabismus:

Eyeglasses or contact lenses: In some cases, wearing corrective lenses can help straighten the eyes and improve vision.
Eye exercises: Special eye exercises can strengthen the eye muscles and improve eye coordination, which can help reduce the severity of strabismus.
Prism lenses: These lenses can help correct double vision caused by strabismus.
Botox injections: Injecting botulinum toxin into the affected eye muscles can help weaken them, reducing the degree of misalignment.
Vision therapy: This type of therapy involves a combination of eye exercises, prism lenses, and other techniques to improve eye coordination and correct strabismus.
Surgery: In more severe cases, surgery may be necessary to correct the alignment of the eyes. During the procedure, the eye muscles get repositioned to improve eye alignment and reduce double vision.

The treatment approach will depend on the type and severity of strabismus, as well as the age and overall health of the patient. Different treatment combinations may be necessary to achieve the best results for some people.

Squint Eye (Strabismus): Surgery Cost

The cost of strabismus surgery in India can vary depending on several factors, including the type and severity of the condition, the surgeon's expertise, the hospital or clinic where the procedure gets performed, and the location within India. However, to give an idea of the average cost, here are some rough estimates:

The cost of strabismus surgery can range from around INR 25,000 to INR 1,50,000, depending on the factors mentioned here.
The cost may be higher for complex cases that require more extensive surgery.
The cost may also vary depending on the type of procedure, as different surgical techniques can get used to treat strabismus.

It's important to note that these estimates are just a general guideline, and actual costs may vary depending on individual circumstances. Patients should consult with a qualified eye doctor to get a fair idea of the expected costs for their specific case.

Squint Eye (Strabismus): Surgery Age Limit

There is no specific age limit for strabismus surgery. The decision to perform surgery depends on the individual case and the severity[3] of the condition. In some cases, surgery may be recommended at a young age to prevent vision problems and to help develop normal visual pathways in the brain. In other cases, surgery may get recommended later in life if the individual is experiencing double vision or has cosmetic concerns.

However, it's important to note that strabismus surgery is generally not recommended for infants under six months, as their visual system is still developing, and the condition may resolve eventually. Ultimately, you should consult an experienced eye doctor before getting strabismus surgery and the surgery timing.

Squint Eye (Strabismus): Surgery Recovery Time

The recovery time[2] for strabismus surgery can vary depending on the individual case and the extent of the surgery. Generally, the recovery period lasts for several weeks. During this time, it is common for the eyes to be red and swollen and for the individual to experience some discomfort or mild pain. Eye drops or ointments may get prescribed to help reduce inflammation.

The following are some general guidelines for the recovery period after strabismus surgery:

The individual may need to wear an eye patch or shield for some time after the surgery.
Avoid strenuous activity, including heavy lifting, for at least a week after surgery.
It is important to avoid rubbing or touching the eyes during recovery.
Follow-up appointments with the eye doctor will be necessary to monitor the healing process and ensure it was a successful surgery.

Overall, the recovery time for strabismus surgery is relatively short, and most individuals can resume their normal activities within a few weeks.

Squint Eye (Strabismus): Surgery Side Effects

While strabismus surgery is generally considered safe[3], there are potential side effects that individuals should be aware of. These can include:

Double vision or blurry vision: Some individuals may experience double vision or blurriness after the surgery, which can last a few days to a few weeks. It is usually temporary and should resolve on its own.
Infection: As with any surgery, there is a risk of infection. Signs of infection include redness, swelling, and discharge from the eye. If these symptoms occur, seek medical attention right away.
Bleeding: There may be some bleeding in the eye after the surgery, which can cause temporary vision problems.
Recurrence of strabismus: In some cases, the strabismus may recur after the surgery, requiring further treatment.
Under- or over-correction: The surgery may result in under- or over-correction of the eye alignment, which can cause persistent or recurring double vision or strabismus.
Loss of vision: In rare cases, strabismus surgery can result in a loss of vision in the affected eye.

It is vital to discuss any potential risks or complications with an eye doctor before undergoing strabismus surgery.

Squint Eye (Strabismus): Surgery Success Rate

The success rate of strabismus surgery can vary depending on the individual case, the severity of the strabismus, and the specific surgical technique used. However, in general, strabismus surgery has a high success rate.

It is important to note that while strabismus surgery can improve the alignment of the eyes, it may not necessarily improve vision or correct any underlying vision problems. An eye doctor can provide more information on the expected outcomes of strabismus surgery in individual cases.

Squint Eye (Strabismus): Problems That Can Occur If A Squint Is Not Treated

If left untreated, a squint (strabismus) can cause several problems[4], including:

Amblyopia (lazy eye): If the brain begins to favor one eye over the other due to the misalignment of the eyes, the other eye may become underused and not develop properly, leading to vision problems.
Double vision: When the eyes are misaligned, the brain may receive two different images, leading to double vision and difficulty seeing clearly.
Depth perception issues: One's ability to perceive depth often gets affected by a squint, making tasks such as driving or playing sports more challenging.
Social and emotional issues: Children with a squint may experience teasing or bullying, affecting their self-esteem and emotional well-being.

It is vital to seek treatment for a squint as early as possible to prevent these complications from occurring.

Squint Eye (Strabismus): Exercise

Exercises for squint eyes get designed to improve the alignment and coordination of the eyes. Here is a list of some that an eye specialist may recommend:

Pencil push-ups:- Hold a pencil at arm's length and slowly bring it closer to your nose. Focus on the pencil until you see double, then try to merge the two images into one image. Repeat this exercise several times a day.
Eye tracking exercises:- Place two objects at different distances and move your eyes between them without moving your head. It can help improve eye movement and coordination.
Brock string exercises:- These exercises involve using a string with several beads tied to it. These beads are arranged at different distances, and the patient gets instructed to focus on each bead. It can help improve depth perception and eye coordination.
Computer programs:- There are several computer programs available that can help improve eye tracking and coordination. You can perform these under the guidance of an eye specialist.
Vision therapy:- This is a customized program of exercises and activities designed to improve specific vision problems, including squint.

It is important to note that exercises alone may not be sufficient to correct a squint and surgery or other treatments may be necessary in some cases. Always consult an eye specialist before beginning any exercises or treatment for a squint.
