Are your eyes swollen? Let's talk about Corneal Edema!

Have you ever woken up in the morning and felt like your eyes were blurry and had a feeling like there was something inside them? Or do you see rings around your eyes when you look at lights? Maybe your eyes hurt and you find it hard to look at the light. These are not just any symptoms, they could be signs of a condition called Corneal Edema , which is swelling of the cornea of ​​your eye. Don’t worry, we’ll talk about this in detail .

What is Corneal Edema?

Simply put, corneal edema is swelling of the cornea of ​​your eye. The cornea is the round, glassy, ​​transparent part of the eye at the front. It's like the lens of a camera. It's important for this cornea to be healthy so that we can see clearly.

So, swelling occurs when a fluid builds up inside this sac. There can be many reasons for this. It can happen if the eye is injured or infected. It can also happen after eye surgery, such as cataract surgery . Sometimes, corneal edema can also occur due to genetic conditions.

How does this affect the eyes?

The inner lining of our eyeballs is a layer of cells called the endothelium . The main function of these endothelial cells is to remove excess fluid from the eyeball and maintain its moisture level. These cells act like a small pump.

So, if there is any damage to these endothelial cells, that pumping process doesn't happen properly. Then the fluid that needs to get out of the vessel gets stuck there, and the vessel starts to swell.

If you have corneal edema, you may develop folds or even ruptures in the tissue in your eye called Descemet's membrane . This membrane is a very important part of the structure of your eye that helps keep it clear.

What are the symptoms of this?

If you have corneal edema, a swelling of the cornea, some of the symptoms may be worse first thing in the morning. This is because when we sleep, our eyes are closed, so fluid builds up inside the eye instead of draining out. Check to see if you have these symptoms:

• Feeling of pain or discomfort in the eye , as if something small is stuck inside the eye.
• Blurred vision.
• Difficulty looking at light (Photophobia). Some people feel this very strongly, as if the light is shining into their eyes.
• Seeing halos around lights.
• Rarely , blisters may occur.
• Corneal microcystic edema is a condition in which swelling is accompanied by the formation of very small blisters.

The most important thing is that if you have any of these symptoms, don't ignore them and see an ophthalmologist immediately.

Why does corneal edema occur?

The main causes of corneal edema are usually the damage to the endothelial cells we talked about earlier, eye injuries, and inflammatory conditions. However, sometimes even doctors cannot find the exact cause. In such cases, it is called idiopathic corneal edema .

Due to eye injuries and surgeries

• Eye injuries: Imagine if you get hit in the eye by a ball while playing cricket, or if you get hit in the eye in a car accident while walking, during a fight, or if a chemical gets in your eye while working in a factory. These injuries can be in the form of scratches, getting something into your eye, or burns.
• Eye surgery: It is normal to experience some swelling after most eye surgeries. This swelling usually goes away within a few weeks. However, for some people, especially those with pre-existing eye conditions, this swelling can be permanent.

Due to eye diseases

Some eye diseases can also cause fluid to accumulate in the cornea, causing corneal edema.

• Iritis: This is an inflammation of the iris of the eye.
• Keratitis: This is an inflammation that occurs in the cornea.
• Fuchs' dystrophy: This is a hereditary condition. In this condition, the endothelial cells in the eye are unable to remove fluid from the eye. This can cause swelling and blistering.
• Glaucoma: This condition damages the optic nerve in the eye. This can cause increased pressure inside the eye, causing swelling.

What are the other reasons?

There are some other reasons that affect this situation.

• Use of certain medications.
• Wearing contact lenses that are too tight on the eye. It is very important to use contact lenses that fit your eyes exactly, clean them and use them for the prescribed period of time.
• Infections.

How do you find this?

To know for sure if you have a swollen eye, you need to see an eye specialist. He or she will first ask you about your symptoms and medical history. Then, they will perform a complete eye exam and carefully examine your eye using special equipment.

The doctor may also do a test to measure the thickness of your cornea, called pachymetry . He or she may also do an ultrasound to examine your eyes.

Another test that can be done is an optical coherence tomography of the anterior segment . This is a test that uses light to reflect light and check the health of your eye. This is a non-invasive, painless test.

What are the treatments?

The doctor will treat the corneal edema and any underlying medical conditions that may be causing or contributing to it. In some mild cases, corneal edema may resolve on its own.

Non-surgical treatment

Your doctor may prescribe other medications, such as topical items or pills or injections.

• Antibiotics for infections.
• Corticosteroids for inflammation.
• Hypertonic solutions to reduce the fluid content of the eye. These can come as eye drops.
• If the pressure in the eye is high due to glaucoma, medication is given to reduce it.
• If there are blisters, special bandage contact lenses can be worn to reduce the discomfort caused by them.

Treatment by surgery

In some severe cases, especially if there are severe scarring, surgery may be necessary.

• A corneal transplant is a surgery to transplant a new cornea. This can be the entire cornea or part of it.
• If the pressure in the eye is high due to glaucoma, surgery is performed to reduce it.

What will the future hold in this situation?

In most cases, if the condition of corneal edema and the underlying medical conditions causing it are properly treated, the prognosis is generally good . This means there is a good chance of recovery.

How can you protect yourself from this?

There are several things you can do to protect yourself from corneal edema.

• Take care of your eyes. Wear protective eyewear while working or playing sports. For example, wear a helmet when riding a motorcycle or bicycle, and wear safety glasses when doing work such as welding.
• Get regular eye exams as recommended by your doctor. That way, if there is a problem, it can be identified early.
• Control other health conditions, especially if you have conditions that can cause corneal edema (e.g., diabetes, high blood pressure).
• If you wear contact lenses, follow your doctor's instructions carefully about how to clean them and how long to wear them.

When should you see a doctor?

If you have symptoms that affect your vision, or cause pain or discomfort in your eyes, be sure to see a doctor.

If you already have an eye condition, follow your doctor's instructions carefully about how often you should see your doctor and how to use your medication.

Remember, Corneal Edema is a very serious eye condition. If your eyes are hurting, or if you have had eye surgery, see your eye doctor right away. You may have another condition that needs treatment. Seeking medical attention early is the best way to get the best results. Your vision is very important to you and the medical team treating you.

Corneal Edema is a swelling of the cornea of ​​the eye. It can cause eye pain, discomfort, and vision problems. It can be caused by eye injuries, infections, surgeries, certain eye diseases, and hereditary conditions. If you have symptoms, especially if your vision is blurry in the morning and you have difficulty seeing in the light, see an ophthalmologist immediately. This condition can be controlled to a large extent with proper treatment. Therefore, do not be afraid and do not delay in seeking medical advice. It is your responsibility to protect your eyes!
