Is your little one's eyes 'lazy'? Let's talk about Amblyopia!

Your little one may not tell you anything about the way he sees. But, have you ever felt like he doesn't use one eye as well as the other, like it's a little "lazy"? This is what we medically call amblyopia, or "lazy eye." Don't be alarmed when you hear this, because this is what we're going to talk about today, very simply.

What exactly is Amblyopia?

Simply put, amblyopia is a condition in which a child's vision in one or both eyes does not develop properly . This is caused by a malfunction in the eye and brain. It's like a team that works well together, but one person doesn't cooperate properly. Often, children get used to this vision problem, so they don't tell their parents about it. This can sometimes go undiagnosed for years. But the best thing is, there is a treatment for it. Seeing an eye doctor can go a long way in correcting this condition. It's important to start treatment early. If it's too late or not diagnosed properly, it can lead to permanent vision loss later on.

What actually happens in amblyopia?

Think of it this way: the connections between a child's eyes and their brain are like little roads. These roads are well-developed from the day they are born until they are about 8 years old. At this time, the child's vision should be transmitted clearly from both eyes to the brain. Now, if for some reason, what is seen in one eye or both eyes becomes blurry, or if something obstructs it, the roads between that eye and the brain do not develop properly. Then the brain cannot properly recognize the image coming from one eye. After a while, the brain starts to ignore the 'unclear' image coming from the eye. Then that eye gradually becomes "lazy", which means that the acuity of vision in that eye decreases. That eye is what we call an "amblyopic eye".

What are the causes of Amblyopia?

There are several reasons that can disrupt this normal connection between the eye and the brain and cause amblyopia. Let's take a look at what they are.

1. Strabismus (crossed eyes)

This is the most common cause. You may have seen some babies whose eyes don't look in the same direction. One eye may be turned inward (that's what "cross-eyed" means), outward, up, or down. When the eyes are not aligned like this, the eye that is straight is dominant. The vision in the straight eye is normal because the connection between that eye and the brain is working properly.

But that misaligned eye doesn't focus properly on an object. Then the brainWhat you do is ignore the signal coming from that eye. Over time, that eye becomes "lazy", which means that amblyopia develops.

2. Deprivation Amblyopia

Not all children with amblyopia have a deviated septum. Sometimes this can be caused by an anatomical problem within the eye. For example:

• Droopy eyelid (ptosis): This prevents the eye from opening properly, obstructing vision.
• Cataract : If a condition such as cataract develops at a young age, it can also cause blurred vision and amblyopia.

Things like this prevent the eyes from seeing clearly.

3. Refractive Error

This is another major cause. Amblyopia can also occur due to certain vision deficiencies.

• Severe far-sightedness (Hyperopia): Near objects appear clear, but distant objects appear blurry.
• Severe nearsightedness (Myopia): Objects that are far away can be seen clearly, but objects that are close up are blurred.
• Astigmatism : This is when light entering the eye is not focused properly, causing blurred vision.

Due to such vision impairments, blurred, unclear images are sent to the brain. Then the brain never gets used to seeing a clear image. This can lead to amblyopia in one or both eyes. Another thing is that the vision of the two eyes is different (Anisometropia). That is, one eye sees better than the other eye. Then the brain "forgets" the eye that sees blurry.

What are the symptoms of Amblyopia? How do you recognize it?

Often, young children with amblyopia don't talk about their vision problems. They get used to it and think it's normal. However, sometimes a parent or a school teacher may notice that their child is having trouble with their vision. Here are some things you might notice:

• The eyes appear to be crossed.
• He squints a lot.
• Tilts head to one side to see better.
• Some children have a clear weakness in judging distance (depth perception) . For example, they have difficulty catching a thrown ball, or they seem a little clumsy when going up and down stairs.

This is why it is so important to have children's eyes checked regularly (regular vision screenings).These types of problems are often identified through tests performed by doctors.

How is Amblyopia treated?

The good news is that there is a treatment for amblyopia! The main goal of treatment is to give the "lazy" eye a task to do and force the brain to focus on the images coming from that eye. This will strengthen the vision in that eye. There are several methods used for this:

1. Glasses

If amblyopia is caused by the refractive errors we discussed earlier, or by a difference in the power of vision between the two eyes (anisometropia), the first thing to do is to wear two glasses. These glasses send clear, focused images to the brain. The brain can then "turn on" the weaker eye. This helps the two eyes work together and develop normal vision.

2. Eye Patches

Often, children with amblyopia need to wear an eye patch on their good, strong eye. This patch needs to be worn for 2-6 hours a day, while the child is awake. Depending on the situation, this may take several months or even years. Of course, it is not easy to tell a young child to keep their eye closed like this. They may not like it at first. But most children get used to it after a while, and it becomes a part of their day. Distracting them, giving them a new toy, taking them to the park, or letting them play outside can help them forget that they are wearing the patch. Just imagine, they can feel like a superhero with one eye closed for a while!

3. Atropine drops

Just as a patch covers the good eye, atropine drops temporarily blur the vision in the good eye. This forces the brain to recognize images coming from the weaker eye. This method works well for mild to moderate amblyopia, but may not be as effective for severe cases.

4. Surgery

If amblyopia is caused by strabismus and cannot be corrected with glasses, patches, or eye drops, eye muscle surgery may be performed. Similarly, if amblyopia is caused by a droopy eyelid or cataracts, surgery may also be performed. This surgery involves loosening or tightening the muscles that are causing the strabismus. This type of surgery usually does not require a hospital stay.

What else do we need to know?

Children's vision is fully developed (visual maturity) around the age of 8. After that, it can be a little more difficult to treat vision problems. Therefore,The sooner amblyopia is diagnosed and treated, the greater the chance of improving vision and preventing permanent vision damage. Therefore, it is important not to panic or panic, but to seek medical advice as soon as possible.

Let's also remember about eye exams for young children.

Sometimes there are no outward signs of a vision problem. That's why it's so important for young children to have a vision screening at least once a year, either through their pediatrician or at school. These tests should start in the toddler and preschool years. This can help catch problems before your child's vision is fully developed. It's also recommended that you get a comprehensive eye exam from an ophthalmologist or optometrist, who specializes in children's eyes.

If you have any questions or concerns about your child's vision, it's always best to talk to your doctor.

Take-Home Message

Okay, so here are some of the most important things we've talked about today to help you remember:

• Amblyopia is a condition that can be successfully treated if identified at an early age.
• If your child is squinting, tilting their head, or you notice any changes in their vision, seek medical advice immediately.
• Treatment options include glasses , eye patches , atropine drops, and sometimes surgery. Your doctor will decide which treatment is best for your child.
• It is very important to start treatment before the child turns 8 years old.
• Getting your child's eyes checked at regular intervals will help prevent serious problems in the future.

Don't worry, with the right understanding we can cope with this situation well!
