Does your little one often bump into objects like a chair or table that are on one side? Or does he tilt his head to one side while watching TV, reading a book, or playing? Have you ever noticed that he looks with one eye slightly closed? When you see these things, some parents may think that these are things that the child does for fun. But this can actually be a sign of a serious problem with the child's vision. Today we are talking about such a condition, 'Amblyopia', which is common among young children.
What is Amblyopia?
Simply put, amblyopia is a condition in which a child's vision in one of their eyes is weaker than the other, causing the brain to gradually "forget" that weaker eye.
Imagine there are two people in a team, but only one does all the work. The other person just sits around. What happens after a while? The one who works gets stronger, and the one who just sits around gets weaker and weaker. This is what happens to our eyes and brain in amblyopia. When the brain receives a clear image from one eye and a blurry image from the other eye, the brain always chooses the clear image. Over time, the brain ignores the eye that sends the blurry image. This causes the vision in that eye to deteriorate further.
Although many people call this 'Lazy Eye' , that is not a very accurate name. Because the child is not lazy, his eyes are not lazy either. This is a developmental problem that occurs without the child's control, in the connection between the brain and the eyes. This is the main cause of vision loss in young children. But the best thing is that if identified early, it can be completely cured .
How do I know if my child also has this condition?
The biggest challenge here is that parents often don't recognize this easily. Because young children don't understand how to say, "Mommy, I can't see with this eye." That's why most children are diagnosed with this condition only after going to the doctor for a routine checkup.
But you can also keep an eye out for these symptoms at home.
| Characteristic | Think about this for a moment. |
|---|---|
| Crashing into things | Do you often bump into objects on the same side of your body, especially when walking or running? This means you may not be able to see things coming from that side properly. |
| Tilting the head to one side | When watching TV, drawing, or looking at a toy, do you turn your head to one side and focus your good eye in that direction? |
| Closing or narrowing one eye (squinting) | Do you cover one eye with your hand when trying to see something clearly? Or do you squint? |
| Eyes not looking in the same direction | The condition we call 'strabismus'. When one eye looks straight ahead, does the other eye turn inward, outward, up, or down? |
| One eye drop | Is one eyelid lower than the other, and is part of the eye covered by the black ring? |
Why do young children develop amblyopia?
The main reason for amblyopia is that, for some reason , the vision in one eye of a child is different from the other. There are several main factors that affect this.
Refractive Errors
This is a condition where vision becomes blurred due to natural changes in the shape or function of the eye. If this defect is more pronounced in one eye, a blurry image is sent to the brain from that eye.
- Myopia: Nearsightedness: Seeing things up close clearly, but seeing things in the distance as blurry.
- Nearsightedness (Hyperopia): Difficulty seeing things up close (such as reading books) clearly, even though you can see clearly in the distance.
- Astigmatism: A condition in which the shape of the cornea of the eye is not perfectly spherical, but rather oval, like an egg, causing objects at any distance to appear distorted or blurred.
Strabismus (eyes not looking in the same direction)
We usually call this 'strabismus' . This is when both eyes are not looking at the same direction at the same time, but one eye is turned in a different direction. When this happens, the brain receives two different images. The brain then selects only the clear image and "forgets" the image coming from the strabismus eye. Over time, that eye becomes weaker.
Structural Eye Conditions
Sometimes, a problem inside the eye can prevent light from entering the eye properly.
- Ptosis: If one eyelid droops to the point where the eye cannot be opened properly, it can interfere with vision.
- Cataracts: This is not something that only happens to older people. Some children can be born with cataracts. When the lens of the eye becomes cloudy, vision becomes blurry.
- Corneal problems: There is some opacity or problem with the transparent part of the front of the eye (the cornea).
The important thing is, whatever the cause, the result is the same. The brain ignores the weak eye. Therefore, treating the cause is the best way to cure amblyopia.
Who is most likely to develop this condition?
Any child can develop amblyopia, but some children are at higher risk.
- If anyone in the family (mother, father, siblings) has amblyopia, strabismus, or severe vision problems.
- If the child has any developmental delays.
- Premature babies (before 37 weeks).
- Low birth weight (birth weight less than 2500 grams).
What happens if left untreated?
This is the most important thing we all need to be aware of. If amblyopia is not treated in a timely manner, it can lead to permanent vision loss in that eye. That is, it can lead to blindness in that eye. This is because the connection between the eyes and the brain is strengthened during the first 7-8 years of a child's brain development. After that time, it is very difficult for the brain to retrain the weak eye.
But don't worry! The good news is that if it's caught early, it can be almost completely cured .
What are the treatments for amblyopia?
The main goal of treatment is to somehow "force" the brain to use the weaker eye. It's like giving someone a job and making them stronger. Your doctor may suggest various methods for this.
| Treatment method | Simply put... |
|---|---|
| Wearing an Eye Patch | This is the most common method. What is done here is that the good eye is closed for a few hours a day. Then the child is forced to work, play, and look, using the weak eye. This strengthens the connection between that eye and the brain. |
| Wearing glasses (Eyeglasses) | If the cause of amblyopia is a vision defect, the first thing to do is to give the child a pair of glasses that are correct for it. Sometimes, just putting on glasses will solve the problem and the brain will start using both eyes. |
| Medicated Eye Drops | Sometimes, the doctor may prescribe a type of eye drop, such as atropine, to be put in the good eye . This medicine temporarily blurs the vision in the good eye. Then, just like a patch, the brain has to use the weaker eye. |
| Surgery | This is not necessary in most cases. It is only done if there is a structural problem that needs to be corrected surgically, such as cataracts, a deviated septum, or squint. |
This treatment can be a little difficult for both you and your child. Your child may cry and try to remove the patch. But you need to patiently and lovingly explain the importance of this. Encourage him by giving him small gifts and letting him play a game he likes (drawing, coloring, playing a video game) while wearing the patch. It is very important to do this treatment exactly as your doctor tells you.
When should I get my child's eyes checked?
Regular eye and vision exams are the best way to catch these problems early. From the day your child is born, your doctor will check your child's eyes during their well-child visits. It's a good idea to have your child's eyes checked at least once a year or two after they start school.
If you have any concerns about your child's vision, see your doctor immediately. He or she will refer you to an eye care specialist if necessary.
Take-Home Message
- Amblyopia is a serious condition that needs to be identified and treated at an early age.
- Always be aware of changes in your child's behavior (head tilting, bumping into things, closing one eye). If you notice these, tell your doctor.
- If treatment is started early, a child's vision can be almost completely restored. Don't delay.
- Follow the treatment methods (eye patch, glasses) exactly as the doctor says, without being lazy. Encourage the child to do so.
- Never skip your child's routine medical checkups. Eye exams are a very important part of this.
