What Is a Cornea?
Your cornea is your eye’s clear, protective outer layer. It acts like a barrier against dirt and germs, and it helps filter out some of the sun’s damaging ultraviolet light.
It also plays a key role in vision. As light enters your eye, it gets refracted, or bent, by the cornea’s curved edge. This helps determine how well your eye can focus on objects close up and far away.
If your cornea is damaged by disease, infection, or an injury, the scars can affect your vision. They might block or distort light as it enters your eye.
Anatomy of the Cornea
Understanding the structure of the cornea is essential for grasping how various conditions affect vision. The cornea is a transparent, dome-shaped layer at the front of the eye that:
- Protects: Acts as a barrier against dust, germs, and other harmful particles.
- Focuses Light: Helps focus light onto the retina, enabling clear vision.
Layers of the Cornea
Your cornea has six main layers:
1. Epithelium : The outermost layer protects your eyes from chemicals, water, and microbes and absorbs nutrients from tears and oxygen. It’s the most sensitive part of the body.
2. Bowman’s layer : The second layer is made up of a strong protein called collagen. It helps form the shape of your cornea.
3. Stroma : The third layer is the thickest layer of your cornea. It’s made up of water and proteins that strengthen and support your cornea. It’s the most important layer for helping your eyes to focus.
4. Dua’s layer : This is the thinnest layer of your cornea. It was only recently discovered, and scientists aren’t sure what its function is yet.
5. Descemet’s membrane : This is a strong layer of tissue that protects your eye against infection and injury.
6. Endothelium : The innermost layer is a very thin layer of cells on the back of the stroma. It works like a pump to drain excess fluid from the stroma. Without it, fluid would build up in the stroma and your cornea. Your cornea would get opaque and hazy, and so would your vision.
Symptoms of Corneal Disease
The term corneal disease refers to many conditions that affect this part of your eye. These include infections, tissue breakdown, and other disorders you get from your parents.
Symptoms depend on the type of cornea problem you have, but you might notice:
- Pain
- Blurred vision
- Tearing
- Redness
- Extreme sensitivity to light
- Vision that gets worse over time
- Pus or discharge from your eyes
- Some cornea diseases don’t have symptoms, especially in the beginning.
How Are Cornea Problems Diagnosed?
Your doctor will examine your eye and do some tests to diagnose the problem. Tests for cornea problems include:
- Slit lamp exam: Your doctor uses a special microscope with a bright light to see the different parts of your eyes. They will customize the brightness and thickness of the light’s beam. Before this test, you may need to have your pupils dilated, or made more open, with eyedrops. This lets more light into your eye, so your doctor can get a better view.
- Fluorescein eye stain test: With this test, your doctor puts a special type of dye, called fluorescein dye, into your eye. Then, they shine a blue light at your eye. The dye makes scratches or other damage easier to see.
How to Prevent Cornea Problems
You can’t always prevent cornea problems, but you can take steps to reduce your risk:
- Keep your contact lenses clean.
- Don’t sleep with contact lenses in, even if the package says you can.
- Wear safety goggles when using machinery or working with chemicals. This includes doing yard work and using tools like hammers and saws.
- Wear protective eyewear when playing sports where something might get in your eye.
- Visit your doctor if you get something stuck in your eye. Don’t try to remove it yourself.
- Get regular eye exams to catch eye problems early.
