Do your eyes turn inward? Let's talk about Esotropia!

Have you ever noticed that some people, especially young babies, have one or both eyes that are slightly turned inward, towards the nose? Some people also call this "cross-eyed." This is what we medically call esotropia . This is actually a minor problem with the position of the eyes. There is nothing to worry about, and if you are aware of this and get the right treatment, it can be cured to a large extent. Shall we talk more about this?

So, what is Esotropia?

Simply put, Esotropia is when one or both of your eyes turn inward, toward your nose. This is actually a condition called Strabismus . Strabismus is when your eyes are not aligned properly, but rather turn in different directions. Some people also call it "cross-eyes." Esotropia can be monocular (eye twitching) or binocular (eye twitching).

Normally, the muscles and nerves that control our eyes work together very skillfully to point our eyes in the same direction. But in someone with esotropia, this coordination is not working properly. Think of it like the wheels of a car not turning in the same direction. Esotropia means the eyes turn inward, while the opposite of this, which is when the eyes turn outward, is called exotropia .

Although this condition can occur at any age, it is most common in young babies and children. This can affect not only the child's vision, but also their social and emotional development. Some children experience low self-esteem and embarrassment due to this appearance. That is why it is very important to seek medical advice, get a diagnosis, and start treatment as soon as you notice these symptoms.

Are there different types of esotropia?

Yes, there are different types of esotropia. Let's see what they are:

• Intermittent esotropia: In this type, the inward turning of the eyes does not always occur. Sometimes the eyes are straight, and sometimes they turn inward. It's like a light going on and off.
• Constant esotropia: In this case, the eye turns inward all the time.
• Infantile or congenital esotropia: This can be present at birth , or it can develop within the first few months of life.
• Alternating esotropia: In this, both eyes are affected, but only one eye turns inward at a time. Sometimes the right eye, sometimes the left eye.
• Accommodative esotropia: This type can often be corrected by wearing glasses or contact lenses. It often occurs in people with farsightedness.
• Nonaccommodative esotropia: This type is difficult to treat with glasses alone. Surgery may be necessary.
• Pseudoesotropia: This is not actually esotropia, but it looks like it. This is because babies have flat noses and extra skin ( epicanthal folds ) at the inner corners of their eyes. This does not require treatment, and the appearance will go away on its own as the baby grows.

What are the symptoms of Esotropia?

The main symptom is one or both eyes turning inward toward the nose. If you have this, you may not notice it. It is often noticeable to others. In addition, you may have these symptoms:

• The eyes do not move together in the same direction.
• Squinting, squinting, and turning your head to one side to see clearly can cause eye strain.
• Problems with depth perception. This means that it is difficult to accurately understand how far away or close something is.
• Diplopia (double vision).
• Amblyopia - This is also called "lazy eye".

What are the causes of Esotropia?

The main cause of esotropia is a lack of coordination between the muscles in your eyes. Normally, the muscles in our eyes work together as a team to help us see the same thing with both eyes (the binocular system). This is why we can tell how close or far something is. It is very important for both eyes to work together when riding a bicycle, driving a car, or reading a book.

Young children with esotropia are often farsighted. This means that they see distant objects more clearly than close objects. Sometimes, esotropia can also be a sign that they need glasses to correct this farsightedness.

Sometimes esotropia is genetic. Other blood relatives in your family may also have eye strain problems.

Additionally, esotropia can also be a symptom of other medical conditions. For example:

• A problem inside one or both eyes, such as a cataract , a problem with the retina, or an issue with the optic nerve .
• A problem affecting your brain. For example, increased intracranial pressure or a brain tumor .
• Conditions related to the nervous system, for example, nerve damage due to stroke or diabetes .
• Eye injuries.
• Thyroid conditions .

What are the risk factors for Esotropia?

There are several risk factors that can contribute to the development of esotropia:

• Preterm birth .
• Someone in the family has strabismus .
• Drug or alcohol use during pregnancy.
• Genetic variations .
• Neurologic disorders .
• High farsightedness.
• Other health conditions, such as hyperthyroidism and diabetes .

What are the possible complications of Esotropia?

Esotropia makes it difficult for your eyes to work together. This can lead to complications such as:

• Double vision .
• Peripheral vision problems - that is, a decrease in the range of vision to the sides when looking straight ahead.
• Loss of 3-D vision and binocular vision.
• Blurry vision .
• Decreased vision in one eye ( Amblyopia ).

Most importantly, these cosmetic concerns can lead to low self-confidence in many people, which can lead to social anxiety and reduced performance in schoolwork and other activities.

How is Esotropia diagnosed?

If you or your child has any of these symptoms, your family doctor will refer you to an eye specialist ( ophthalmologist ) or optometrist . The doctor will ask you about your family and medical history, then perform an eye exam. The following tests may also be done:

• Visual acuity test - to see how clearly you can see.
• Refraction test - measuring how well the eyes focus light with the correct lenses.
• Alignment and focus tests.
• Pupil dilation (widening) test - Check the health of the structures inside the eye.

What are the treatments for Esotropia?

Some cases of esotropia may resolve on their own. However, if they do not, your eye doctor may recommend one or a combination of these treatments:

• Glasses or contact lenses.
• Amblyopia treatment (covering the eye with a strong patch or using dilating eye drops to blur the vision in the strong eye).
• Prisms - These are a special type of lens that is attached to glasses.
• Botulinum toxin (Botox® ) injection - This temporarily weakens the eye muscles.
• Strabismus surgery .

Important: If you have esotropia as a symptom of another medical condition, your doctor will treat the underlying condition. Usually, controlling the underlying condition will also help the esotropia resolve.

Can Esotropia be prevented?

Esotropia cannot be completely prevented, but you can help manage the condition by taking your child for regular eye exams as soon as you notice any changes in their eyes or vision.

What is the outlook for someone with esotropia?

If you are receiving treatment for esotropia, such as wearing glasses, using contact lenses, or having surgery, your prognosis is very good. The most important thing is to follow your treatment plan exactly and see your doctor regularly for checkups.

When should my child see a doctor about esotropia?

If your child is having trouble with their eyes – meaning they are constantly squinting, or if you notice they are moving their eyes from side to side to see things clearly – see a doctor immediately. This is also true for you.

If your or your child's eyes suddenly change or look different, especially after an accident, see a doctor immediately. It's especially important to get help quickly after an accident.

What questions should I ask my child's doctor?

You can ask your child's doctor questions like these:

• What type of esotropia does my child have?
• What treatment options do you recommend?
• Does my child need surgery?
• What should I do to prevent Esotropia from recurring?
