Does your baby have tears in his eyes? Let's learn about Blocked Tear Duct and Tear Duct Probe in a simple way!

Does your little one's eyes constantly leak tears ? Or does it look like they're filled with tears? Sometimes this can be a little scary for parents. But don't worry. Most of the time, this is caused by a condition called blocked tear ducts, which is common in young children . Today, we'll talk about what a blocked tear duct is and a simple treatment called a tear duct probe.

What exactly are these tears? What is a tear duct?

First, let's look at what these tears are, how they are produced, and why we need them. Think of it like our eyes are like two little cameras. This camera lens, that is, the eye, needs to be kept moist and clean at all times. That's what tears help with.

There are small glands located under our upper eyelids, on the outside of our eyes. We call these the lacrimal glands . They are like a water tank. These glands produce tears. These tears flow down the surface of the eye, spread throughout the eye, moisten the eye, remove dirt and debris, and clean it. Not only that, but these tears can also fight germs that enter the eye.

Now, just as we need to get rid of used water, these used tears also need to be removed from the eye. That's what the tear duct system is for. Think of it like the drainage system in our house. At the inner corner of the eye, on the upper and lower eyelids, there are two small holes (`(Puncta)`). Tears enter through these holes, travel through small tubes (`(Canaliculi)`) and collect in a small bag called the tear sac (`(Lacrimal Sac)`) . Then from there, they travel through another long tube (`(Nasolacrimal Duct)`) and collect in the nose. That's why when we cry a lot , tears also come out of our nose. Do you understand?

Why do these tear ducts get blocked?

Okay, now we know how tears are formed and how they drain from the eye. So why do these tear ducts get blocked?

We often see this condition in newborn babies . The reason for this is that, as mentioned earlier, the tear duct connects to the nose, and at the end of that duct is a small membrane (`(Membrane)`). This membrane is closed when the baby is in the womb. Usually, this membrane opens automatically when the baby is born or a few days after birth. However, in some babies, this membrane may not open. That is when the tears have no way to go to the nose, and they get stuck in the eyes, and the tears have to escape from the eyes. We call this congenital nasolacrimal duct obstruction (`(Congenital Nasolacrimal Duct Obstruction)`) . This is the main reason for the blockage of the tear duct in babies.

There can be other reasons why tear ducts become blocked in older children or adults. For example:

• Eye or nose infections (`( Infections )`)
• Injuries to the eyes or nose
• Changes that occur with age
• Some lumps that form in the nose (`(Nasal Polyps)`)
• Very rarely, conditions such as tumors (`(Tumors)`) can occur in the tear duct system. However, these are very rare.

That's why, if you or your baby has these symptoms, you should definitely see a doctor, especially an ophthalmologist . They can then find the exact cause.

How do you know if a tear duct is blocked?

Now you're probably thinking, 'I don't know if my baby has this problem too.' So, let's see what are the symptoms of a blocked tear duct.

• Constantly wet and tearful eyes (`( Epiphora )`) : This is the main symptom. Even when the baby is not crying, tears can be seen in the eyes and sometimes running down the cheeks.
• Mucopurulent discharge : Mucopurulent discharge, especially when you wake up in the morning, may accumulate around the eyelids. This can sometimes cause the eyelids to stick together.
• Redness or swelling of the inner corner of the eye : The area where the tear sac is located (`(Lacrimal Sac Area)`) can sometimes become red, swollen, and painful to touch. This can happen if the tear sac is infected (`(Dacryocystitis)`). If this happens, you should see a doctor immediately .
• Trying to wipe their eyes frequently : Babies may feel uncomfortable because their eyes fill with tears. So they often try to wipe their eyes with their hands.
• Eyes look blurry : Sometimes vision can become a little blurry due to excessive tear production.

Remember, if your baby has one or more of these symptoms, the best thing to do is to see an ophthalmologist . They can look at it closely and tell you if it's a blocked tear duct, and if so, what to do about it.

What can be done? Basic steps.

Okay, so now you've seen the doctor and it's confirmed that your baby's tear duct is blocked. What treatment will the doctor give you?

In most cases, especially for newborns, doctors don't immediately resort to major treatment. Because, as mentioned earlier, most babies' blocked tear ducts open on their own within the first year.So, the first thing to do is to wait a little patiently.

At the same time, the doctor will teach you how to massage the tear sac (`(Crigler Massage)`) . This is very simple.

• First, you need to wash your hands thoroughly with soap.
• Then, place your index finger (some people also use your pinky finger) on the inner corner of your baby's eye, in the small bump between the nose and eye (where the tear duct is), and gently press down and rub towards the nose . As if sending a little message.
• The doctor says to do this two or three times a day, about five or six times at a time.

This massage increases the pressure in the tear sac and helps to open the blocked membrane.

Additionally, if your baby's eyes are crusty, meaning they have a mild infection, the doctor may prescribe an eyewash and antibiotic eye drops to control the infection . When cleaning the eye, use a cotton swab dipped in clean, sterile water to wipe the eye from the inside to the outside. Do not reuse the same swab.

Most of the time, these simple things resolve the problem within a few months. But if that doesn't happen, we're thinking about the next step.

What is a tear duct probe?

Imagine, even after a few months of massage, the baby's tears have not stopped flowing. Or, they are constantly getting eye infections. That's when doctors think about a treatment called a tear duct probe .

Simply put, this is the process of opening a blocked tear duct using a thin instrument . This is done by an ophthalmologist . This is usually considered a minor surgery, but it does not involve a large incision.

The device used for this is called a 'probe' . It is a very delicate, thin, metal rod-like instrument. It has a smooth surface, so it does not damage the tear duct. It is used to gently push away the blocked membrane or other small obstruction, making a path for the tears to flow.

How is this test/treatment done?

Now you're probably wondering how to do this, and will it hurt the baby? Don't worry, I'll explain that too.

When doing this `(Probing)`, small babies are usually given general anesthesia (`(General Anesthesia)`) . This means that the baby is put to sleep for a while. This is done so that the baby does not feel anything, is not afraid, and does not move. Then the doctor can do this very easily and safely. Sometimes, for slightly older children or adults, this can be done using only local anesthetic eye drops (`(Local Anesthetic Eye Drops)`). That is up to the doctor to decide.

After administering anesthesia, the doctor will do the following:

1. First, the small hole (`(Punctum)`) at the inner corner of the eye mentioned earlier is made slightly larger, using a delicate instrument.

2. Then, the `Probe`, a thin metal rod , is very carefully inserted through that hole and passed down the nasolacrimal duct.

3. When this `Probe` is passed, if there is a blocked membrane or other small obstruction, it will gently break. This will create a path for the tears to flow.

4. Finally, the doctor will inject sterile saline solution (`(Sterile Saline Solution)`) into the tear duct with a small syringe to see if the passage is open and the fluid is flowing into the nose. It is like cleaning a blocked pipe by running water through it. Sometimes, a dye (`(Dye)`) is added to this saline solution and the color is seen coming out of the nose, which can confirm that the passage is open.

The entire process only takes a few minutes , so the baby doesn't need to be under anesthesia for a long time.

What happens after the test?

Okay, now the `(Probing)` is over. What happens next?

• In most cases, the baby can go home the same day. After waking up from anesthesia, they are monitored for a while before being sent home.
• For the first few days, you may have some watery eyes, perhaps pinkish tears (with a little blood) . You may also have some discharge from your nose. This is normal, don't worry . It will go away in a few days.
• The doctor will most likely prescribe antibiotic eye drops or ointment for a few days. It is given to prevent infection. It should be used exactly as the doctor says, for the exact duration.
• Sometimes, the doctor will tell you to continue the tear sac massage as you did before for a few more days . This will help keep the newly opened tear duct from closing again.
• The doctor will ask you to come back for a follow-up appointment to check on the situation.

The success rate of this ``(Probing)`` treatment is very high , especially when done on babies under one year old. In most cases, the problem is completely resolved after just one treatment.

Are there any risks involved?

As with any medical procedure, probing is not without its risks. However, it is generally a very safe procedure . Complications are rare when performed by an experienced ophthalmologist.

Things that could happen are:

• Infection : The chance of this happening is very low, because antibiotics are given after treatment.
• Bleeding : Usually there is very little bleeding, which stops on its own.
• Making a wrong path (`(False Passage)`): When the `probe` is passed, it is possible for it to go in a different direction and form a new path instead of the actual tear duct. However, this is very unlikely to happen with an experienced doctor.
• Scarring : Scarring can form inside the tear duct and cause it to become blocked again. This is also very rare.
• Recurrence of Blockage : Sometimes, even after probing, the tear duct can become blocked again after a while. If this happens, you may need to do another probing, or you may need to do another treatment (for example, placing a small tube in the tear duct - stenting - or even more complex surgery). But your doctor will explain this to you.
• Risks of Anesthesia : If your baby is given general anesthesia, there are some risks associated with it. The anesthetist will explain these to you thoroughly before the treatment.

The most important thing is to ask the doctor any questions or concerns you may have. They will explain everything to you.

Finally, remember this.

Okay, so let's remind you of a few things we talked about today that we think are important to you.

• Blocked tear ducts are very common in young babies , so don't worry too much about it.
• In most cases, this condition improves on its own by the time the baby is about a year old , or is cured with simple massage techniques.
• If that doesn't work, a tear duct probe is a very safe and effective treatment .
• If your baby's eyes are constantly watering or crusting, you should definitely see an ophthalmologist . They will be the ones who can examine them properly and give you the best advice for you and your baby.
• Talk to the doctor thoroughly and ask and clear all your questions and doubts . It is your right.

So, I hope this discussion has been helpful to you. I wish your baby a speedy recovery!
