Have you ever noticed something different when you look at your little one's eyes? Maybe one eye looks a little strange, or their vision seems a little blurry? If you see something like that, don't take it lightly. Today we're going to talk about a problem that might come to your mind at such a time, and that is a condition called Coats Disease . This is a rare eye disease that usually affects young children, especially boys.
What is Coats Disease? Let's understand it very simply.
Simply put, Coats Disease is a condition that occurs when the blood vessels inside your child's eye do not develop properly. This specifically affects the retina, which is the back of the eye. Think of it this way: if our eye is like a camera, the retina is like the film inside it. When light enters the eye, it detects images and sends messages to the brain through this retina.
So, in Coats Disease, the tiny blood vessels in the retina become swollen and twisted, and they start to leak or leak fluids like plasma . This is like a water pipe that has a hole in it and is leaking water. Although it may not cause much damage right away, over time, this leakage can damage the retina and affect vision.
This disease usually affects one eye. However, it can rarely affect both eyes at the same time. Although it is most often diagnosed in young children and adolescents, it can occur at any age. This can lead to vision loss, serious complications such as retinal detachment, and eventual blindness in that eye. Therefore, it is important to see a doctor immediately if you notice any changes in your child's eyes or vision.
What are these symptoms? How do you recognize them?
Coats Disease may not cause any symptoms in the early stages. However, as the disease progresses, the child may show symptoms such as:
- Vision is gradually decreasing: Your child may feel like they can't see clearly in one eye. You may notice things like moving closer when watching TV or squinting when reading a book.
- Strabismus: One eye appears to be turned in a different direction than the other.
- Eye pain: Some children may also complain of eye pain.
- Leukocoria: This is a somewhat unusual symptom. When you look at the pupil of your child's eye , or take a photo, it may appear to be white or silvery. This is sometimes called "cat's eye." If you see this sign, you should definitely see a doctor immediately.
Imagine, when your son is playing, you notice that he can't see clearly with one eye, or when you take a photo at night, there's a white spot in the black iris of one eye. That's what could be happening here.
What are the stages of Coats Disease?
Coats Disease is divided into several stages, depending on how it progresses, which is like a staircase.
- Stage 1: This is the most basic stage. Here, the ophthalmologist can see that the child has abnormal blood vessels inside the eye, but the child has not yet experienced any discomfort or symptoms due to them.
- Stage 2: This is where fluid begins to leak from the abnormal blood vessels, which can often affect the child's vision.
- Stage 3: When the disease reaches this stage, the child's retina begins to detach (Retinal Detachment). This is a slightly more serious condition.
- Stage 4: In the fourth stage, the child's eyes may develop glaucoma , a disease in which the pressure inside the eye increases.
- Stage 5: This is the most severe and final stage of Coats Disease. At this point, the affected eye may become completely blind.
The most important thing is that no matter what stage the disease is in, the sooner it is diagnosed and treated, the greater the chance of preserving the child's vision.
Why does Coats Disease occur?
In fact, experts still have not been able to find a cause for Coats Disease (idiopathic ). That is, it often occurs spontaneously, without any specific cause.
Another important thing is that Coats Disease is not a genetic disorder . That is, it is not a hereditary disease that is passed down from generation to generation. Even if no one in your family has had it, your child can still develop it. Also, just because one of your children had it, there is no need to worry that other children will also develop it.
Who is more likely to develop this? (Risk factors)
Although anyone can develop Coats Disease, some people are at higher risk.
- It has been found that boys are about three times more likely to develop this disease than girls.
- Looking at age:
- Doctors often diagnose this in children and young adults under the age of 16 .
- Very rarely, some babies can be born with this condition, or it can appear a few months after birth.
- It is also reported that about one-third of people with Coats Disease are adults over the age of 30 .
How does a doctor recognize this? (Diagnosis)
When you see a doctor, especially an ophthalmologist , after noticing something different in your child's eyes, the first thing he or she will do is thoroughly examine the child's eyes.
- He examines the child's eyes from the outside as well as inside using special instruments.
- A visual acuity test is performed to check the child's vision. This involves measuring vision by showing them letters and pictures and having them read them.
In addition, one or more of the following special imaging tests may be performed to confirm Coats Disease:
- Optical Coherence Tomography (OCT) scan: This takes a picture of a cross-section of the retina.
- Angiography test: This involves injecting a special dye into a vein in your arm and taking pictures as it passes through the blood vessels in your eye . This allows you to clearly identify any leaks.
- Ultrasound scan: This can look at the inside of the eye.
- An MRI (Magnetic Resonance Imaging) scan.
- A CT scan (Computed Tomography scan).
These tests allow the doctor to know exactly what is happening inside the eye, the extent of damage to the blood vessels, and whether fluid is leaking.
What are the treatments?
The treatment for Coats Disease depends on the stage of the disease in the child. For example, if the disease is detected very early (stage 1 or early stage 2) , the child may not need any treatment at all. In such cases, the ophthalmologist will regularly examine the child's eyes and look for changes in the blood vessels in the retina.
However, if the child has severe symptoms, or if the disease is in a more severe stage, there are treatments such as:
- Cryotherapy: This involves using extreme cold to freeze and destroy the abnormal blood vessels, which then stops them from leaking fluid.
- Drug Treatment: An ophthalmologist can inject an anti-VEGF (Anti-vascular endothelial growth factor) drug directly into the child's retina. This medication helps stop fluid from leaking from those blood vessels and prevents retinal detachment.
- Surgery: If the child is in a severe stage of the disease, or if a condition such as retinal detachment has developed, surgery may be required to repair the damage.
What can I expect if my child has Coats Disease?
The impact that Coats Disease has on a child's eyes and vision depends on when the disease is diagnosed and how well the eye responds to treatment. Studies have found that the older a child is when the disease is diagnosed, the less likely it is to progress to a more severe stage .
If Coats Disease is diagnosed early (stage 1 or 2), the child is less likely to have serious, long-term effects. However, even with treatment, the affected eye may still have some degree of vision loss (low vision).
If the disease has progressed to a more severe stage, there is a higher risk of blindness in the affected eye. That is why we recommend that you see a doctor as soon as possible, even if you notice the slightest change.
What other complications can this cause?
During the course of Coats Disease, a child is at increased risk of developing other eye conditions, such as:
- Glaucoma
- Cataracts
- Uveitis ( inflammation of tissue inside the eye)
- Neovascularization
Therefore, it is very important to follow the doctor's instructions carefully and to go for tests on time.
Can Coats Disease be prevented?
Because this disease occurs very randomly, without any specific cause, there is really nothing we can do to prevent Coats Disease.
However, once the disease is diagnosed, it is essential to have regular follow-up eye exams as recommended by an ophthalmologist to monitor changes in the child's retina. This will help identify any worsening of the disease and take necessary steps.
When should I see a doctor?
If you notice any changes in your child's eyes or vision, see a doctor or ophthalmologist right away. Don't delay.
Also, if you experience any of these symptoms, go to a hospital emergency department immediately :
- Sudden loss of vision.
- Severe eye pain.
- It can be described as seeing flashes of light or seeing floaters in front of the eyes.
What questions should you ask the doctor?
When you go to see the doctor, you might want to ask questions like these:
- What stage of Coats Disease is my child in?
- How often do I need to come for follow-up exams?
- Does the child need treatment?
- What kind of treatment does he need?
- How much will Coats Disease affect his vision?
Ask questions like these and clear all your doubts. The doctor will explain everything to you.
What is the difference between Coats Disease and Retinoblastoma?
Coats Disease and Retinoblastoma are two conditions that affect the retina of young children.
- Coats Disease is a condition in which the blood vessels in a child's retina develop abnormally, causing fluid to leak into the eye.
- Retinoblastoma is a rare type of cancer that develops in the retina. Although it is a cancer, if the tumor has not spread outside the eye, most children can live cancer-free after treatment.
The early symptoms of both diseases are very similar. In particular, the white appearance of the black iris (leukocoria) can be seen in both. Therefore, if you notice any changes or symptoms in your child's eyes, it is essential to see an ophthalmologist immediately to find out exactly what it is. The doctor can perform tests and tell you exactly which of these two diseases it is.
Take-Home Message
Coats Disease is a rare condition that affects the small blood vessels in the retina, the back of your child's eye. This causes fluid to leak from those blood vessels, damaging vision.
The most important thing to remember is that the best way to reduce the impact this disease has on a child's eyes and vision is to catch the disease in its early stages.
So, if you notice even the slightest change in your child's eyes or the way they see things, don't ignore it and see a doctor or an ophthalmologist immediately. If detected early, there is a much greater chance that your child's vision can be saved with treatment. Don't worry, doctors are there to help you and your child.
