Have you ever noticed that the white part of some people's eyes, that is, the white sclera, has become a little blue? Perhaps you have noticed this change in your own eyes. This is quite common in young babies. So, in medicine, when the white part of the eye takes on a blue, gray or purple color, we call it 'Blue Sclera'. Most of the time, this is nothing to worry about. However, sometimes this can be a symptom of another medical condition inside our body. So today, let's talk about everything in a simple way.
What exactly is 'Blue Sclera'?
Simply put, the white part of our eye is called the sclera. It is actually a thick covering made up of strong connective tissue fibers. Its main function is to protect the eye and maintain its shape.
Imagine, what happens if this white wall called the sclera becomes a little thinner for some reason? At that time, the dark tissue (uvea) and the color of the blood vessels underneath it become visible through this thin white wall. It's like when you put something blue under a thin white cloth, you can see the blue color on top. That's why we call it Blue Sclera . Usually, this condition does not cause eye pain or other symptoms.
Is this always a serious condition?
No, most of the time it's not. The severity of this depends on the cause of the blue eyes.
- Young babies: The sclera of newborns and young babies is naturally a little thinner. So it's normal for the whites of their eyes to look a little blue. As the baby grows, this sclera thickens, and the blue color disappears.
- Adults: This condition can occur due to simple reasons such as iron deficiency in some adults.
But remember, sometimes this can be a symptom of a serious medical condition. Therefore, if you notice any changes in your or your child's eyes, it's best to see a doctor without ignoring it. Your doctor will likely perform an eye exam, blood tests, or genetic testing to determine the exact cause.
What are the main causes of blue eyes?
The causes of Blue Sclera can be divided into several categories. Let's look at them in a table, so it's easier to understand.
| Cause Category | Examples and Details |
|---|---|
| Genetic Conditions | These are congenital conditions that can be passed down through generations.
|
| Other Diseases & Conditions |
|
| Medications and other external causes |
|
What are the treatments for this?
It is very important to understand this. Blue Sclera is not a disease, but a symptom. Therefore, doctors do not treat the blue color of the eyes, but the underlying disease that caused the blue eyes.
- If you suspect iron deficiency , your doctor may recommend iron supplements or iron-rich foods. Once your iron levels return to normal, the blueness in your eyes may gradually disappear.
- Cause of Osteogenesis ImperfectaIf it's a genetic disease, like Down syndrome, treatment is focused on managing the disease. This may require the help of a team of specialists.
- If it's caused by a medication, the doctor will consider changing or stopping that medication.
That means that the treatment depends entirely on the underlying cause. That's why it's essential to seek medical advice and not self-medicate.
When should you seek immediate medical advice?
If you notice any change in the color of the whites of your eyes, it's best to see a doctor without panicking. However, if the blue eyes are accompanied by the following symptoms, you should go to a hospital's Emergency Department (ETU) immediately .
- Sudden change in vision
- Blurred vision
- A liquid like tears flows from the eyes.
- Sensitivity to light (blue eyes)
- Severe eye pain
These can be signs of a serious eye problem, so it is important to seek treatment without wasting time.
Take-Home Message
- Blue Sclera is when the white of the eye (sclera) turns blue, gray, or purple.
- This is caused by the thinning of the sclera, which allows the underlying tissue to show through.
- While this is often a harmless condition, it can sometimes be a symptom of an underlying condition, such as iron deficiency or genetic disorders.
- The treatment does not address the blue color of the eyes, but the underlying medical condition that caused it.
- If you notice any of these changes in your eyes, especially if they are accompanied by other symptoms such as eye pain or blurred vision, see your doctor immediately.
👩🏽⚕️ Additional questions (FAQs)
💬 Selexipag / Uptravi tablets are a very specific medicine given for which disease?
This is not an ordinary medicine! This is a highly successful and expensive medicine in the world (Prostacyclin receptor agonist) that is given to the final stages of 'Pulmonary Arterial Hypertension (PAH),' a fatal disease in which only the blood vessels that go from the heart to the lungs become narrowed, and the blood pressure in them increases abnormally, causing 'lungs and heart to die'!
💬 When blood flow to the lungs is reduced, how does taking these pills (Uptravi) dilate the blood vessels?
A chemical called 'Prostacyclin' is naturally present in the body to enlarge/dilate the blood vessels that carry blood to the lungs (Pulmonary arteries), but PAH patients do not have it. When this pill enters the body, it goes directly to the receptors (IP receptors) in the blood vessels of the lungs and presses a button! Then the brain is fooled into thinking that 'Prostacyclin' has arrived, and then all the constricted blood vessels in the lungs immediately relax (Vasodilation), and the burden on the heart disappears immediately.
💬 What are the unbearable side effects of taking the medicine (Selexipag) given for this serious disease?
Most of the side effects of this come from the fact that it presses on the blood vessels throughout the body (Prostacyclin effect)! The most common side effects are unbearable 'headaches' (due to the blood vessels becoming larger), severe muscle and jaw pain (Jaw pain / Myalgia), and diarrhea! Also, sudden flushing (flushing) can definitely be a big problem.
