Blocked Tear Ducts (Lacrimal Ducts) – What They Are & Why They Get Blocked

Tears are supposed to do a quick lap across your eyeball, grab dust and drama, then exit through a tiny drainage system into your nose.
When that exit ramp is blocked, tears don’t politely disappearthey hang around, overflow, and make you look like you just watched the
saddest movie trailer ever… on loop.

A blocked tear duct (also called nasolacrimal duct obstruction) happens when tears can’t drain the normal way.
The result is usually watery eyes (epiphora), sticky discharge, crusting, irritation, and sometimes infections.
It’s common in babies, and it also happens in adultsoften for totally different reasons.

What a “Tear Duct” Actually Is (Quick Anatomy, No Pop Quiz)

Your tear system has two main jobs: make tears and drain tears.
The tears are produced by the lacrimal gland (up and out toward the outer part of the eyelid), then they wash across the eye toward the inner corner
near your nose. That’s where the drainage starts.

In the inner corner, tiny openings called puncta act like little drains. Tears flow from puncta into small channels
(canaliculi), then into the lacrimal sac, and finally down the nasolacrimal duct into the nose.
That’s why crying can give you a runny noseyour face is basically a connected plumbing system.

What Counts as a Blocked Tear Duct?

A blocked tear duct can be partial (tears drain slowly) or complete (tears basically don’t drain).
The blockage can happen anywhere along the drainage pathwayfrom the puncta to the nasolacrimal duct.

In babies, it’s often a “new construction” issue: the duct may not be fully open at birth.
In adults, it’s more like “an older house with narrow pipes”: inflammation, scarring, injury, infection, or age-related narrowing can interfere with drainage.

Symptoms: What It Feels Like When Tears Can’t Leave

A blocked tear duct doesn’t always hurt. In fact, one of the most annoying things about it is how mild-but-constant it can be.
Common signs include:

• Watery eyes (tears spilling onto the cheek even when you’re not emotional)
• Mucus or discharge (especially after sleep)
• Crusting on eyelashes or lids
• Redness or irritation from constant moisture
• Blurred vision that improves when you wipe tears away
• Recurrent eye infections or “pink eye” that keeps coming back

When It Might Be an Infection (Don’t Ignore These)

Sometimes a blockage leads to infection in the lacrimal sac (dacryocystitis). Red flags can include:
swelling and tenderness near the inner corner of the eye, warmth/redness, pus-like discharge, and sometimes fever.
If you see significant swelling, pain, fever, or spreading redness around the eye, it’s time to get medical care promptly.

Why Tear Ducts Get Blocked in Babies

A blocked tear duct is incredibly common in infants. Many babies are born with a nasolacrimal duct that’s narrow or still covered
by a thin membrane near the duct’s end (a common “finish line” spot for congenital blockage).
You might notice tearing and discharge in the first weeks or monthsoften when tear production ramps up.

Typical baby symptoms

• Tears pooling or spilling over, often in one eye
• Sticky yellowish discharge or crusting, especially after naps
• Skin irritation under the eye from constant wetness

The good news: most infant blocked tear ducts improve on their own during the first year.
That’s why pediatric providers often start with conservative care before jumping to procedures.

Why Tear Ducts Get Blocked in Adults

In adults, blocked tear ducts can happen for a lot of reasonssome straightforward, some less common.
Common categories include:

1) Age-related narrowing or “idiopathic” blockage

Tear drainage structures can narrow over time. Sometimes there’s no single dramatic causejust gradual change and inflammation that leads to scarring.

2) Inflammation and chronic irritation

Ongoing inflammation of the nose or sinuses, eyelid inflammation (blepharitis), or chronic eye irritation can contribute to swelling and narrowing.
Allergies don’t usually “plug” a duct like a cork, but they can make tearing worse and complicate the picture.

3) Infection

Infections can cause swelling and scarring in the drainage system. Sometimes infection is the result of a blockage, and sometimes it helps create one.
Either way, repeated infections are a clue that drainage isn’t working well.

4) Injury, surgery, or facial trauma

A broken nose, facial injury, or surgery near the nose or eye can change anatomy or create scarring that narrows the drainage pathway.

5) Less common causes (but important)

Rarely, a growth in the nose or nearby structures can compress the drainage system.
This isn’t meant to scare youjust to explain why persistent, one-sided tearing in an adult sometimes needs a thorough evaluation.

Blocked Tear Duct vs. Dry Eye vs. Pink Eye

Here’s the twist: watery eyes don’t always mean your eye is “too wet.”
Sometimes dry eye triggers reflex tearingyour eyes overproduce watery tears because the surface is irritated.
Meanwhile, “pink eye” (conjunctivitis) tends to cause redness and discharge, often with irritation or contagious exposure (depending on type).

A blocked tear duct often features overflow tearing and recurrent crusting/discharge, sometimes without intense itch or burning.
The patterns matter, and an exam can help sort out the real cause.

How Doctors Diagnose a Blocked Tear Duct

Diagnosis usually starts with a history (How long? One eye or both? Infections? Injury?) and a careful eye exam.
Depending on age and symptoms, clinicians may use:

• External exam of eyelids, puncta, and the inner corner area
• Dye tests that track how quickly tears drain
• Irrigation/flush testing to see if fluid passes through the drainage system
• Imaging (in selected cases) if anatomy needs clarification or if a secondary cause is suspected

For babies, the diagnosis is often clinicalbased on classic symptoms and a normal-looking white part of the eye (instead of the diffuse redness you’d expect with conjunctivitis).

What You Can Do at Home (Safe, Common First Steps)

Home care depends on age and the situation. The goal isn’t to “DIY fix” your tear duct like it’s a clogged sinkplease don’t go fishing around your eyelid.
Instead, conservative care focuses on keeping things clean and reducing irritation while the body resolves the issue (especially in infants).

For babies: gentle cleaning + provider-guided massage

Many pediatric providers recommend keeping the eyelids clean and teaching caregivers a gentle tear duct massage technique
(often described as a downward motion near the inner corner of the eye).
Done correctly, it may help open a thin membrane and improve drainage over time.
Your child’s clinician should show you exactly where and how to do it safely.

For adults: protect the eye surface and reduce triggers

Adults with constant tearing often benefit from managing things that make tearing worse:
wind, smoke, strong fragrances, and poorly controlled allergies.
Warm compresses can feel soothing, and good eyelid hygiene helps if blepharitis is part of the story.
If symptoms persist, though, home care usually isn’t enough to fix a true obstruction.

Medical Treatments: From “Wait and See” to Procedures

Infants: watchful waiting, then simple procedures if needed

Because most congenital cases improve during the first year, clinicians often start conservative.
If the duct stays blocked beyond the expected window or infections keep happening, an eye specialist may recommend a procedure such as:

• Probing: a small instrument helps open the duct (commonly used if symptoms persist)
• Balloon dilation: a tiny balloon expands a narrow area
• Silicone intubation/stenting: a soft tube keeps the pathway open while healing occurs

These are medical procedures (not home projects). The “right” timing depends on the child’s age, severity, and whether infections or complications occur.

Adults: treat the cause, and consider surgery for lasting relief

If there’s an infection, treatment may include antibiotics.
If the blockage is caused by inflammation, addressing underlying nasal/sinus issues may helpbut many adult obstructions don’t fully resolve that way.

For persistent obstruction, a common definitive treatment is dacryocystorhinostomy (DCR),
which creates a new drainage pathway so tears can bypass the blocked segment.
DCR can be done through a small external incision or endoscopically through the nose, depending on anatomy and surgeon preference.

Complications: Why It’s Not “Just Annoying Tears”

Many blocked tear ducts are more irritating than dangerousbut ignoring ongoing symptoms can increase the chance of complications, including:

• Dacryocystitis (infection of the lacrimal sac)
• Repeated conjunctivitis-like episodes
• Skin irritation and breakdown from chronic wetness
• In rare cases, spreading infection around the eye (urgent)

The main reason to get evaluated is simple: you want to prevent repeat infections and protect eye comfort and health.

When to See a Doctor (Quick Reality Check)

It’s smart to get medical advice if:

• Watery eye symptoms last more than a few weeks without improvement
• You have recurring discharge/crusting or repeated “pink eye”
• You notice swelling, pain, fever, or worsening redness near the inner corner
• Tearing is mostly on one side in an adult and doesn’t go away
• Vision changes occur (beyond temporary blur from tears)

Can You Prevent a Blocked Tear Duct?

You can’t always prevent itespecially congenital casesbut you can reduce irritation and infection risk:
keep eyelids clean (especially if you’re prone to blepharitis), remove eye makeup thoroughly, manage allergies,
protect your face during sports, and don’t ignore sinus/nasal issues that keep flaring up.

FAQ: Fast Answers to Common Questions

Is a blocked tear duct contagious?

The blockage itself isn’t contagious. If there’s an infection causing discharge, that infection may be contagious depending on the organism and situation.

Why do my eyes water more outside?

Wind and cold air can trigger reflex tearing. If drainage is already slow, the overflow becomes more obvious outdoorslike your eyes are auditioning for a soap opera.

Can a blocked tear duct go away on its own?

In babies, it often doesmany resolve in the first year. In adults, spontaneous resolution is less common unless the cause is temporary swelling or inflammation.

Does a blocked tear duct cause dry eye?

It usually causes the opposite (watery eyes), but dry eye can exist at the same time and trigger reflex tearingso you can feel dry and look teary. Yes, your eyes can be complicated like that.

Conclusion: The Short Version (That’s Still Actually Helpful)

Blocked tear ducts are a drainage problem, not a “too many tears” personality trait.
In infants, it’s commonly a developmental issue that often improves with time and basic care.
In adults, blockage is more likely due to narrowing, inflammation, infection, injury, or scarringand persistent cases may need medical procedures for real relief.
If tearing is constant, one-sided, or comes with swelling and pain, it’s worth getting checked so you can stop wiping your face every five minutes and start feeling normal again.

Experiences People Commonly Share (Real-World, Not Medical Advice)

People describing a blocked tear duct often sound less like they’re reporting an “eye symptom” and more like they’re explaining a new lifestyle:
always carrying tissues, checking mirrors for crusting, and doing that subtle under-eye dab that tries to look casual but definitely isn’t.
Since everyone’s anatomy and triggers are different, experiences varybut a few themes pop up again and again.

1) “I look like I’m crying… but I’m literally ordering groceries.”

Adults with nasolacrimal duct obstruction frequently describe tears that spill over during normal activitieswalking outside, cooking over steam,
stepping into air-conditioning, or getting hit with a gust of wind. Some say the tears feel “trapped,” as if the eye keeps producing fluid but it has nowhere to go.
Others notice the tearing is worse at the end of the day when their eyes are tired, irritated, or exposed to screens and dry indoor air.

2) “One eye is fine. The other eye is a faucet.”

A classic experience in adults is one-sided watering. People often say it’s not dramatic at firstjust a slightly wet eye on certain daysthen it becomes
more consistent. They might wipe their cheek constantly, notice makeup running on one side, or feel embarrassed in conversations because it looks like they’re tearing up.
Many only seek care after it starts interfering with driving (blur from tears), reading, or social comfort.

3) “It’s not pink eye, but it keeps acting like it.”

Another common story is recurring crusting or discharge that looks like conjunctivitis, especially in the mornings.
People describe waking up with sticky lashes, then improving during the dayuntil the cycle repeats.
Some get treated for “pink eye” multiple times before anyone looks closely at the drainage system and realizes the real issue is that tears and mucus
aren’t draining normally. When a clinician explains it, many people have the same reaction: “Wait… there’s a tear drain?”

4) Parents of babies: “The eye is watery and gunky, but my baby seems totally unbothered.”

For infants, caregivers often notice persistent tearing and mild discharge without the baby acting sick.
That detail matters: in many blocked-tear-duct cases, the white part of the eye can look fairly normal even when the lashes get crusty.
Parents often describe it as “a leaky eye” that comes and goes, sometimes worse in cold weather or when the baby has a stuffy nose.
Many say the most stressful part is not knowing whether they’re missing something serious, especially if it’s their first child.

5) The “massage routine” experience (and the learning curve)

When providers recommend tear duct massage for a baby, parents often describe a short learning phase: figuring out the right spot near the inner corner,
being gentle but consistent, and not feeling like they’re bothering their child. Many report it becomes part of the daily rhythmlike burping, diaper changes,
and the never-ending quest to locate the pacifier that vanished into another dimension.
Some caregivers notice gradual improvement over weeks, while others see little change and eventually move on to an in-office procedure.
Either outcome is common, and most parents feel relieved once they have a plan and a timeline.

6) When infection shows up, the story changes fast

People who develop dacryocystitis often describe a clear shift: instead of “annoying tearing,” they get swelling near the inner corner,
tenderness, and discharge that looks more intense. Parents may notice the area looks puffy or red. Adults may say it feels sore to touch
or that the skin around the corner of the eye is hot and irritated. This is often the moment people stop hoping it will “just clear up”
and seek urgent carebecause it feels like a normal nuisance turned into a real problem overnight.

7) Post-treatment reactions: “I didn’t realize how much time I spent wiping my face.”

After successful treatmentwhether an infant procedure or adult surgerymany people describe a surprisingly emotional realization:
they had adapted so well to constant tearing that they forgot what “normal” feels like. They notice they can go outside without tearing immediately,
read without blur, and talk to others without looking misty-eyed. Parents of babies often mention the biggest win is not the aesthetics,
but the comfortless crusting, less irritation, and fewer repeat visits for suspected infections.

If any of these experiences sound familiar, the key takeaway is that persistent watery eyes aren’t something you have to “tough out.”
The cause is often identifiable, and treatmentespecially when matched to age and severitycan be very effective.
