Do you know about these two types of fluids inside the eye? (Aqueous Humor & Vitreous Humor)

We all know how precious our eyes are. But we don't think much about the little things inside our eyes, like the fluids like water, do we? In fact, these fluids help a lot in keeping our eyes healthy and spherical. Today we are going to talk about two of the most important fluids inside our eyes that we don't talk about much. They are Aqueous Humor and Vitreous Humor.

Simply put, what are Aqueous Humor and Vitreous Humor?

These two names may sound a little complicated, but it's very simple. They are both fluids found inside our eyes.

  • Aqueous Humor: This is the clear fluid in the front of our eye. Like the air in a car's tire, this fluid is what keeps the eye hydrated by providing the necessary pressure. This fluid is constantly being produced inside our eyes, and old fluid is being removed. It also provides the eye with the nutrients it needs.
  • Vitreous Humor: This is a slightly thick, gel-like fluid. This fluid takes up most of the space inside the eye. To be precise, the space between the lens and the retina inside the eye is filled with this gel called Vitreous Humor. This is what gives the eye its spherical shape.

Why are these two fluids so important to our eyes?

These two liquids do more than we think for our vision and eye health.

Function of Aqueous Humor:

Its main function is to precisely control the pressure inside the eye (ocular pressure). Imagine, the amount of fluid entering the eye and the amount of fluid leaving it should be equal. If this balance is lost, the pressure inside the eye can increase. That can be a very dangerous situation, and we'll talk about that later.

Function of the Vitreous Humor:

This gel is what gives the eye its beautiful, spherical shape. It also helps to provide the eye with the necessary nutrition. It is attached to the retina at the back of the eye. The retina is like the film in a camera, and it is from there that we send what we see as a message to the brain. So, this Vitreous Humor helps the light to reach the retina.

What diseases can be associated with these fluids?

Here we understand how important it is to have your eyes examined. Because any condition is much easier to treat if it is identified early. Below are some of the main conditions that can occur with these two types of fluids.

Medical conditionSimply put...
Glaucoma This is what many people have heard of as "increased eye pressure." When the aqueous humor fluid does not drain properly, the pressure inside the eye increases. This can damage the optic nerve, which carries messages from the eye to the brain. Glaucoma is the second leading cause of blindness in the world.
Posterior Vitreous Detachment As we age, the vitreous humor gel inside the eye becomes less fluid and begins to separate from the retina. This can cause floaters, small black dots, and spider webs to appear in front of the eye. Sometimes, flashes of light can also be seen. If you experience these symptoms, it is important to see your doctor right away.
Uveitis This causes the parts inside the eye to swell. Symptoms can include redness and pain. It can also affect the parts that make the aqueous humor.
Age-related macular degeneration (AMD) Age-related Macular Degeneration (AMD) is a leading cause of vision loss in people over the age of 50. It is caused by changes in the vitreous humor with age. This affects vision directly in front of you.

What symptoms should you be concerned about?

If you notice any changes in your eyes, don't ignore them as a minor issue. See your doctor immediately, especially if you have any of the following symptoms:

  • If you see objects like black dots, balls of thread, or cobwebs floating in front of your eyes (Floaters).
  • If you suddenly see flashes of light inside your eyes.
  • If your vision becomes blurred or your vision decreases.
  • If you look at the bulbs and see colored rings around them (halos).
  • If you have eye pain or a headache.

These symptoms, especially if they start suddenly, can be an emergency. So don't waste time and see a doctor.

How does the doctor examine your eyes?

When you see an ophthalmologist, he or she will examine your eyes thoroughly. This is nothing to be afraid of. Here are some of the tests that are usually performed:

  • Vision testing: You may remember that test where you have to read letters from a distance. These tests measure the state of your vision.
  • Tonometry: This is used to check for glaucoma. Sometimes a small amount of air is blown into the eye and this test is done. It doesn't hurt.
  • Dilation: The doctor will put eye drops in your eye to dilate the pupil. This will allow you to see the inside of your eye, such as the retina and nerves. Your vision may be slightly blurry for a while after this medicine is applied.

Things we can do to keep our eyes healthy

It is our responsibility to protect our eyes. By following these simple steps, you can keep your eyes healthy.

  • Get good nutrition: Include green vegetables, fruits, and fish like salmon and tuna in your diet.
  • Avoid smoking: Smoking is very harmful to the eyes.
  • Exercise: Exercise helps control body weight and can reduce the risk of eye diseases like diabetes.
  • Get your eyes checked regularly: It is very important to have your eyes checked by a doctor at least once a year.
  • Protect your eyes: Wear good sunglasses when in the sun. Wear safety glasses if you work with machinery.
  • Follow the 20/20/20 rule: If you spend a lot of time looking at your computer or phone, look away from the screen for 20 seconds every 20 minutes. This will give your eyes a good rest.

Our vision is a priceless asset. Therefore, it is important for us to be aware of these small but important parts of the eye, such as the Aqueous Humor and the Vitreous Humor. If you notice any changes in your vision, do not ignore it. See your doctor as soon as possible and seek advice.
