Do your eyes turn outward too? Let's talk about exotropia!

Have you ever noticed that your little one, or perhaps someone you know, has one or both eyes turned slightly outward, towards the earlobes? Or does he or she close one eye while watching TV or when he or she is outside in bright sunlight? Sometimes you may see him or her tilting his or her head to one side. These are some of the symptoms of a condition called ``Exotropia'' that we are going to talk about today. Don't worry, this is something that many people have, and let's talk about it in detail and simply.

Simply put, what is exotropia?

Exotropia (pronounced "ex-so-tro-pee-ya") is a misalignment of the eyes. In medicine, we commonly refer to this condition as "strabismus." You may have also heard the term "crossed eyes," which is what it is.

So, in this `(Exotropia)`, one or sometimes both eyes turn outward, that is, towards the side where the ears are. If only one eye turns outward in this way, we call it `(Monocular Exotropia)`. If both eyes turn outward in this way, it is called `(Bilateral Exotropia)`.

You may have heard of a condition called `(Esotropia)`. It is when the eyes turn inward, that is, towards the nose. This `(Exotropia)` is the opposite of that. Although this condition is most often seen in young babies and children, it can sometimes occur in adults as well.

The most important thing is to seek medical advice immediately if you suspect that your child's eye is turning outward. This is because a child with such an eye can have vision problems, and this appearance can affect the child's self-confidence and social relationships. Therefore, it is best to get a diagnosis and start treatment as soon as possible.

What are the main types of exotropia?

There are also different types of ``Exotropia''. Let's see what the main ones are:

• Intermittent Exotropia: This is the most common type. As the name suggests, it is not always present. It comes and goes. For example, your child may turn their eyes outward when they are very tired, or when they have an illness like a cold, or when they are stressed. This can also be seen when looking at something far away.
• Constant Exotropia: In this type, one or both eyes are constantly turned outward. This condition can be seen when looking both near and far. This is not as common as the previously mentioned Intermittent Exotropia.
• Infantile or Congenital Exotropia: This means that this condition is present at birth or in early infancy.
• Sensory Exotropia: This occurs in an eye that already has poor vision. The eye with poor vision turns outward because it cannot work together with the other eye.
• Alternating Exotropia: This is when both eyes turn outward alternately at different times. This is different from Unilateral Exotropia (where only one eye always turns outward).
• Consecutive or Secondary Exotropia: This type occurs after surgery to treat Esotropia (eyes turning inward).

What are the symptoms of exotropia?

Let's see what common features can be seen in this situation:

• One or both eyes sometimes or always turning outward.
• Squinting.
• Eye strain.
• Headache.
• Double vision or Diplopia.
• Keeping one eye closed when the sun is shining brightly.
• Decreased depth perception.

If you or your child has one or more of these symptoms, be sure to see an ophthalmologist.

Why does this exotropia occur?

There are several reasons for this. Let's see what they are:

• Genetics: In some families, this condition (strabismus) is passed down from generation to generation.
• Eye muscle weakness: This can happen when the muscles that control eye movement do not function properly.
• Convergence Insufficiency (CI): This is when the eyes are unable to focus on a single point when looking at something close.
• Nervous system conditions: Exotropia can also be caused by conditions such as stroke or brain tumors.
• Severely impaired vision: If vision in one eye is very poor, that eye may turn outward.

Sometimes, especially for intermittent exotropia , a specific cause may not be found.

Who is more likely to develop exotropia? (Risk factors)

There are some factors that increase the risk of this condition. They are:

• Neurologic disorders.
• Preterm birth.
• Drug and alcohol use during pregnancy.
• Genetic variations.
• Uncorrected refractive errors (e.g., not wearing glasses) `(Uncorrected refractive errors)`.
• Having someone in the family with the condition `(Strabismus)`.

What happens if treatment is not given? (Complications)

If this `(Exotropia)` condition, especially `(Intermittent Exotropia), is not treated, it can eventually become a `(Constant Exotropia)` condition. Also, if this condition increases during childhood, the child can develop a condition called `(Amblyopia)`. That is, the vision in one eye is weak. Also, the ability to see things in three dimensions by working together with both eyes (Binocular Vision) can be lost.

How is exotropia accurately diagnosed? (Diagnosis)

You may notice that your child's eyes are turning outward. Or your family doctor may notice this. (Sometimes the person with exotropia doesn't even realize it.) They may refer you to an ophthalmologist or optometrist.

Your child's doctor will ask about your family's medical history and your child's medical history. Then they will do an eye exam. This exam will look at how your child's eyes move and focus. These tests may include:

• Visual Acuity Test: Having children read letters from a chart, or in the case of young children, testing how they see things.
• Refraction Test: A test that measures how light is focused in the eyes by having them look through a series of different lenses. Children do not need to speak or answer these tests.
• Eye alignment and focus testing: These tests check how well the child's eyes are aligned and how clearly they can see.
• Dilating the pupil of the eye to check the health of the structures inside the eye.

What are the treatments for exotropia?

Treatment varies depending on the severity of the condition. Sometimes, intermittent exotropia is not that severe, or it may get better on its own over time. Treatment options include:

• Eye patching: This involves covering the better-seeing, stronger eye with a patch and making the weaker eye work harder to strengthen it.
• Eye drops: This is a medical procedure that, like applying eye patches, provides more stimulation to the weak eye.
• Corrective lenses: The doctor may recommend glasses or contact lenses.
• Visual therapy: If your child has the aforementioned convergence insufficiency, eye exercises may help.
• Botulinum Toxin (Botox®): Injecting Botox® into the eye muscles can help realign the eyes.
• Surgery: The doctor may perform surgery to tighten or loosen the muscles in one or both eyes.

Can this exotropia be prevented?

There is no way to prevent this condition from occurring. However, if you are pregnant or planning to become pregnant, it is a good idea to talk to a genetic counselor about the risk of passing this condition on to your child.

What is the future for those with this condition? (Recovery)

Exotropia can get better over time, but most types never completely go away. Non-surgical treatments can help control the condition, but many people have a chance of the condition recurring.

When should my child see a doctor?

Always see a doctor if your child has any symptoms that worry you. These may include:

• Eye pain.
• Double vision.
• Blurred vision.
• Headache.
• The appearance of the eye turning outward.

What should I ask my child's doctor?

Here are some questions you can ask your doctor:

• What type of exotropia does my child have?
• What treatment options do you recommend?
• Does my child need surgery?
• If I have surgery, what are the benefits and risks?

Can exotropia cause blindness?

If left untreated, exotropia can lead to a condition called "lazy eye" (amblyopia), which is the loss of vision in one eye. If left untreated, binocular vision can be lost and distance vision can be impaired. However, complete blindness is not usually the case.

Does exotropia get worse with age?

If left untreated, `(Exotropia)` tends to get worse over time. It can be controlled, but it may never go away completely. Some researchers believe that the permanent solution to `(Intermittent Exotropia)` is to repair the brain, but this is not currently possible.

If your child has ``(Exotropia),'' the condition can affect their self-esteem. It can also make it difficult to build and maintain relationships with others. When someone talks without making eye contact, they may seem inattentive or preoccupied with something else.

That's why it's so important to see an eye specialist as soon as you notice this problem. Especially for children, it's essential to get an eye exam to make sure all eyes are healthy and seeing well. While you can't prevent this from happening, you can take action and get treatment early.

Let's remember the most important things (Take-Home Message)

Okay, so let's summarize the most important things to remember from what we've talked about:

• Exotropia is the turning of one or both eyes outward (towards the ears). This is a type of strabismus, or cross-eye.
• Although this is most commonly seen in children, it can also occur in adults.
• Early detection and treatment can minimize vision problems and the impact on a child's self-confidence.
• Treatments include eye patches, eye drops, glasses, eye exercises, Botox® injections, and surgery.
• If you have any concerns about your child's eyes, see an ophthalmologist without delay.
• This condition can be controlled, but may not be completely cured. However, with proper management, you can live a good life.

I hope this information is helpful to you. If you have any further questions, please consult a doctor.
