Frequently asked questions

Punctal atresia (also called punctal agenesis) means the tiny tear-duct opening at the eyelid margin—the lacrimal punctum—never formed or is completely sealed over. Because the opening is missing, tears cannot enter the drainage system properly, so they spill over the eyelids and run down the cheek (watering eyes, or epiphora). Doctors call it “agenesis” or “atresia” when the opening is absent from birth; this is different from punctal stenosis, where a punctum exists but is narrowed or scarred shut later in life. True atresia is usually congenital and may be accompanied by under-development of the canaliculi (the small tear tubes behind the punctum). EyeWikiPMCPubMed

In a typical eye, each eyelid (upper and lower) has a small opening at the nasal corner called a punctum. Each punctum connects to a channel (canaliculus) that carries tears into the lacrimal sac and then into the nose. During fetal development, a surface ectoderm cord hollows out to form this drainage pathway. If this process fails near the eyelid margin, the punctum may not form at all, leaving a smooth or membrane-covered lid margin. In many patients with punctal atresia, the canaliculi behind the missing opening are also absent or atretic, which influences treatment choices. When both puncta are missing and no useful canaliculus is present, bypass surgery with a tiny glass tube (a Jones tube) is often required to create a new drainage pathway. EyeWikiPubMed+1

Your eyes make tears all the time. Tears keep the front of the eye smooth, clean, and comfortable. After tears wash the eye, they must leave the eye through a tiny drain hole at the edge of each eyelid, near the nose. This tiny drain hole is called the punctum (plural: puncta). There is a punctum on the upper eyelid and a punctum on the lower eyelid on each eye. Each punctum connects to a small channel called the canaliculus, which then carries tears into the lacrimal sac and down the nasolacrimal duct into the nose. When the punctum is open and in the right position, tears flow quietly into the nose and you do not notice them.

Punctal atresia means the punctum is missing, closed, or sealed over. The opening did not form properly before birth (congenital), or it became closed later in life because of scarring or disease (acquired). In simple words: the drain hole is not open, so tears cannot get into the drainage channels. When tears cannot drain, they overflow onto the cheek (this is called epiphora). The eye may feel wet, sticky, or blurry. The skin around the inner corner of the eye can get irritated. Some people also get repeated eye infections because tears and mucus are not clearing well.

You may also hear related terms:

Punctal agenesis: the punctum never developed at all, so there is no opening.
Imperforate or membranous punctum: a thin layer of skin covers the place where the opening should be.
Punctal stenosis: the punctum exists but is very small or tight. This is not true “atresia,” but it causes similar problems because the opening is too narrow for normal drainage.
Canalicular atresia: the channel behind the punctum did not form. This can exist with punctal atresia.

Knowing which type you have is important because it changes how doctors test and treat the problem. In very young babies with a thin membrane over the punctum, a small office procedure can sometimes open it. In people with missing puncta or deeper scarring, surgery is more complex and aims to create a useful opening and connect it to a working drainage channel.

Types

Congenital complete punctal atresia (agenesis)
There is no visible punctal opening at the eyelid margin because it never formed before birth. The tiny drainage channel behind it may also be missing or blocked.
Congenital membranous (imperforate) punctum
The punctum is in the right place but is covered by a thin skin-like membrane. The canaliculus behind it may be present. A small puncture under a microscope can sometimes open it.
Congenital punctal atresia with canalicular atresia
Both the punctum and the canaliculus did not form. Tears cannot enter or travel through the system. Surgery is usually more involved.
Isolated punctal atresia
Only the punctum area is affected. The rest of the tear drainage system may be normal.
Syndromic punctal atresia
The punctal problem occurs as part of a wider pattern of birth differences (for example, certain ectodermal or craniofacial conditions). Other facial or eyelid structures may also be affected.
Unilateral punctal atresia
One eye is affected. The other eye may be normal.
Bilateral punctal atresia
Both eyes are affected. Watering is usually more obvious.
Acquired punctal occlusion (cicatricial)
The punctum was once open but closed later due to scarring from inflammation, infection, allergy, burns, medications, radiation, or surgery.
Punctal stenosis (acquired narrowing)
The punctal opening became smaller and tighter. This is not full atresia but can behave like it by slowing drainage.
Punctal malposition with functional closure
The punctum is present but turns away from the tear lake because of eyelid malposition (for example, outward turning of the eyelid). The opening cannot “catch” the tears, so it acts like it is closed.

Causes

Developmental failure of canalization
During fetal life a small epithelial “plug” should open to form the punctum. If the plug does not open, the punctum remains closed at birth.
Associated canalicular non-development
Sometimes the channel behind the punctum does not develop, so even if a surface opening is created, drainage still fails.
Family or genetic patterns / syndromes
Some rare genetic conditions that affect skin, hair, teeth, or facial structure can also involve missing or closed puncta.
Craniofacial developmental differences
Broader facial development problems can include abnormal eyelid or inner canthus formation and punctal atresia.
Eyelid margin scarring from chronic blepharitis
Long-standing eyelid margin inflammation can cause thickening and scarring that narrows or closes the punctum.
Ocular cicatricial pemphigoid (OCP)
This autoimmune scarring disease can involve the conjunctiva and puncta, leading to closure.
Stevens–Johnson syndrome / toxic epidermal necrolysis
Severe mucous membrane reactions can scar the puncta shut.
Trachoma or other scarring infections
Old infections that scar the inner eyelids can also scar the punctal area.
Herpes zoster or herpes simplex involving the eyelid
Viral damage and secondary scarring can close the punctal opening.
Chemical or thermal burns
Burns around the eyelid margin can scar the punctum and nearby tissues.
Radiation therapy to the eyelids or nearby skin
Radiation can cause delayed scarring and closure of small openings like the punctum.
Eyelid surgery scarring
Surgery near the punctum (for example, blepharoplasty, tumor removal) can leave scar tissue that closes the opening.
Chronic allergic eyelid dermatitis
Ongoing allergic inflammation and rubbing can thicken the tissue around the punctum and narrow it.
Contact dermatitis from cosmetics or skin products
Repeated irritation from makeup or cleansers can inflame and scar the punctal rim.
Topical medication toxicity or preservatives
Long-term use of some eye drops, especially those with strong preservatives, can inflame and scar the punctal area.
Systemic chemotherapy causing canalicular scarring
Some cancer drugs (for example, certain taxanes or antimetabolites) can scar the tear channels and secondarily affect the punctal region.
Intentional punctal closure for severe dry eye (cautery)
Doctors sometimes close puncta on purpose to keep tears on the eye. Later, the closure may be permanent.
Complications of punctal plugs
Plugs placed to treat dry eye can rarely cause local inflammation or granulation tissue that leads to scarring and closure after removal.
Autoimmune skin diseases (e.g., lupus, sarcoidosis) with eyelid involvement
When these conditions scar the eyelid margin, the punctum can close.
Eyelid malposition (ectropion) with chronic exposure
The punctum can evert away from the tear lake and become functionally closed; chronic dryness and crusting then promote narrowing.

Symptoms

Constant watery eyes (epiphora)
Tears do not drain through the punctum, so they spill over the eyelid and run down the cheek.
Blurred vision that comes and goes
A thick layer of tears washes across the cornea and makes the image smeary.
Sticky eyelids, especially on waking
Mucus and tears dry on the lashes overnight and glue the lids together in the morning.
Stringy or mucous discharge
Poor drainage allows mucus to collect along the inner corner and lash line.
Recurrent mild eye infections
Stagnant tears can encourage bacterial growth, leading to repeated conjunctivitis.
Redness or irritation at the inner corner
Skin stays wet, becomes soft and sore, and can look red or raw.
Burning or stinging sensation
Tears mix with eyelid oils and debris and can irritate the ocular surface.
Light sensitivity in bright or windy places
Wind pushes tears out faster, and bright light bothers an already irritated surface.
Tearing worse outdoors or in cold weather
Cold wind increases tearing; without drainage it overflows quickly.
Soreness from frequent wiping
Constantly dabbing the eye with tissues can chafe the skin and make it more inflamed.
Social or work disturbance
Visible tearing can be embarrassing and may interrupt reading, computer work, or driving.
Crusting on the lashes
Dried mucus and tear salts form crusts at the lash base.
Heaviness of the eyelids
Wet, irritated lids can feel heavy or fatigued.
Occasional swelling near the inner corner
If downstream pathways are also narrow, fluid and mucus can bulge the area slightly.
Watery eyes despite feeling dry
Reflex tearing may increase because the eye surface is not being cleared properly, so you can feel both wet and dry at the same time.

Diagnostic tests

(Grouped by category; each described in simple, practical terms)

A) Physical examination

Slit-lamp examination of the punctal area
The doctor looks closely at the eyelid margin under a microscope. They check if a punctal opening exists, where it sits, and whether a thin membrane covers it. This is the most direct way to see if the punctum is missing, sealed, tiny, or turned away from the tear lake.
Eyelid position and tone assessment
The doctor gently evaluates whether the eyelid turns in or out, sags, or is too loose. A turned-out eyelid pulls the punctum away from the tear lake and mimics closure. Correcting lid position may fix “functional” blockage.
Lacrimal sac palpation (pressure over the inner corner)
The doctor presses gently over the lacrimal sac to see if mucus or tears reflux onto the eye. Reflux suggests a blockage downstream. If nothing refluxes and the punctum looks closed, the entry point is likely the problem.
Skin and lash margin inspection
The doctor looks for redness, crusts, thickening, scars, or signs of chronic inflammation. These clues point to acquired causes like blepharitis, dermatitis, or scarring diseases.

B) Manual/office functional tests

Fluorescein Dye Disappearance Test (FDDT)
A safe yellow dye is placed in the tear film. The doctor checks how quickly the color fades over a few minutes. If the punctum is closed, the dye remains, showing slow clearance.
Attempted punctal dilation under magnification
With a tiny dilator, the doctor tests whether a membrane can be gently opened. If the tip meets a solid wall instead of an opening, this supports true atresia or agenesis.
Lacrimal syringing/irrigation (when an opening exists or after creating one)
A fine cannula is placed at the punctum to flush sterile saline. Easy flow into the nose is normal. Reflux back out suggests blockage at or just behind the punctum or farther along the channel.
Gentle probing of the canaliculus (when feasible)
A thin, smooth probe is passed to feel the internal pathway. A “soft stop” suggests blockage inside the canaliculus; a “hard stop” at the lacrimal sac fossa is normal. In atresia, probing is only possible after a safe opening is made.
Tear Break-Up Time (TBUT)
The same yellow dye is used to see how quickly dry spots appear on the cornea. A short TBUT indicates poor tear quality. This helps separate reflex watery eyes from true drainage failure.
Schirmer I test (without anesthesia)
A small paper strip at the eyelid edge measures tear production over five minutes. Normal quantity with persistent overflow points toward an outflow problem like punctal atresia.

C) Laboratory and pathological tests

Tear osmolarity
A tiny sample of tears is tested for salt concentration. Abnormal numbers suggest an unstable tear film. This does not diagnose atresia directly but helps identify added dry-eye components that may worsen symptoms.
Conjunctival or lid margin culture (when discharge is present)
If infections repeat, a swab checks which germs are present and which antibiotics work best. Clearing infection improves comfort while the structural problem is addressed.
Conjunctival biopsy with immunofluorescence (when scarring disease is suspected)
A very small tissue sample can confirm autoimmune scarring disorders such as ocular cicatricial pemphigoid. Treating the underlying disease can prevent the punctum from closing again after surgery.

D) Electrodiagnostic tests

Orbicularis oculi EMG (blink muscle testing)
Small surface or fine-needle recordings measure the strength and timing of the blink muscle that powers the tear pump. Weak or uncoordinated blinking can act like drainage failure and may coexist with punctal problems.
Facial nerve conduction studies (select cases)
If facial nerve weakness is suspected, nerve testing can explain poor lacrimal pump action. This helps the team plan surgery and decide whether eyelid tightening is also needed.

E) Imaging tests

Dacryocystography (DCG)
Contrast dye is gently injected into the drainage system through an available opening (often after creating a punctal opening). X-ray images show where the dye stops. A stop at the very entrance indicates punctal or canalicular blockage.
Dacryoscintigraphy (DSG)
A tiny amount of radioactive tracer is placed on the eye surface. A special camera tracks its movement over time. This test measures how tears travel dynamically and is useful when the anatomy looks confusing.
MR dacryocystography or orbital MRI
MRI shows soft tissues without radiation. It can reveal missing or scarred canaliculi, the lacrimal sac, and surrounding structures, and it helps in surgical planning when standard probing is not possible.
CT dacryocystography or orbital CT
CT is useful if bone or trauma changes are suspected. It shows the bony canal and can guide reconstruction if nearby bones are distorted.
High-resolution anterior segment OCT (or ultrasound biomicroscopy) of the punctal area
Non-contact imaging can outline the punctal rim and the very first segment of the canaliculus. It helps confirm whether a thin membrane is present and measures the opening after surgery.

Dietary molecular supplements

Note: Supplements do not open a missing punctum. Some people find them helpful for general ocular surface comfort; evidence strength varies. Discuss with your clinician, especially if pregnant, on anticoagulants, or have chronic illness.

Omega-3 fatty acids (EPA/DHA)
Dose: ~1,000–2,000 mg/day combined EPA+DHA with meals.
Function: Supports meibomian oil quality; anti-inflammatory.

Flaxseed oil (ALA source)
Dose: 1–2 g/day (or 1–2 Tbsp ground flaxseed in food).
Function: Plant omega-3 precursor; secondary support for tear quality.
Mechanism: Conversion to EPA/DHA (variable), anti-inflammatory properties.
Vitamin A (within RDA; avoid excess)
Dose: RDA adults ~700–900 µg RAE/day from diet; avoid megadoses.
Function: Supports conjunctival/goblet cell health.
Mechanism: Epithelial differentiation and mucin gene regulation.
Vitamin D (if deficient)
Dose: As tested and prescribed (often 800–2,000 IU/day).
Function: Immune modulation; may support ocular surface in deficiency states.
Mechanism: Nuclear receptor–mediated anti-inflammatory signaling.
Vitamin C

Function: Gut–immune axis balance that may indirectly support inflammation control.
Mechanism: Microbiome modulation; ocular-specific evidence is limited.

Regenerative / stem cell” therapies

There are no approved “stem-cell drugs” or immunity boosters that correct punctal atresia. The following biologic or regenerative surface therapies may be considered for ocular surface disease that accompanies tearing, but they do not replace surgical creation of a drainage opening:

Autologous serum eye drops (ASEDs)
Dose: Often 20–50% serum, 4–8×/day (special compounding).
Function: Epithelium-healing and symptomatic relief in severe surface disease.
Mechanism: Delivers growth factors and vitamins present in tears/serum. Evidence shows modest, short-term symptom and staining improvements versus saline/tears, with low-certainty data; use is individualized. PMCPubMed
Platelet-rich plasma (PRP) eye drops
Dose: Compounded; 4–8×/day per specialist protocol.
Function: Similar goal as ASEDs, with more platelet-derived growth factors.
Mechanism: PDGF/EGF/TGF-β support epithelial healing (evidence evolving).
Amniotic membrane (in-office, self-retaining ring or lens)
Dose: Applied by clinician for several days then removed.
Function: Calms inflammation and promotes epithelial repair during severe surface flares.
Mechanism: Anti-inflammatory and pro-healing matrix applied to ocular surface.
Rebamipide 2% ophthalmic suspension (where available, e.g., Japan)
Dose: Typically 4×/day.
Function: Mucin secretagogue that supports goblet cells and epithelial stability.
Mechanism: Up-regulates mucin and improves staining/subjective symptoms in dry eye; regional availability. PMC
Diquafosol 3% (mucin/aqueous secretagogue; Japan/Korea)
Dose: Typically 6×/day.
Function: Enhances mucin and aqueous secretion to stabilize the tear film.
Mechanism: P2Y2 receptor activation increases MUC5AC and fluid; meta-analyses support efficacy for dry eye. PMCPubMed
Scleral lenses (device, not a drug)
Dose: Daily wear, clinician-fit.
Function: Creates a liquid reservoir over the cornea to protect and hydrate the surface.
Mechanism: Seals the ocular surface under a saline-filled vault; symptom relief in severe surface disease.

Again, these do not open a missing punctum; they are supportive options when the ocular surface itself needs healing.

Surgeries

Punctal membrane excision / simple punctotomy (for thin congenital veil)
Procedure: Under magnification, the thin membrane over an otherwise formed punctum is incised and the opening is gently dilated.
Why it’s done: In rare cases where a true punctum is present but covered by a veil, opening it may restore drainage.
Three-snip punctoplasty (for punctal stenosis, not agenesis)
Procedure: Small cuts are made to enlarge a narrowed punctum; often combined with brief stenting.
Why it’s done: Widens a scarred or tiny punctum to let tears enter. Evidence supports three-snip as an effective technique for stenosis; restenosis can occur and follow-up is needed. PMC+1
Canaliculoplasty with silicone intubation (if canaliculus present but tight)
Procedure: The canaliculus is gently probed and a soft silicone tube is placed for weeks to months to keep the pathway open.
Why it’s done: Maintains patency while healing to reduce re-scarring.
Conjunctivodacryocystorhinostomy (CDCR) with Jones tube
Procedure: A small glass tube is placed to connect the conjunctival surface directly to the nasal cavity, bypassing missing canaliculi.
Why it’s done: Gold-standard bypass when puncta/canaliculi are absent or destroyed; it provides a new, permanent tear path. Patients need tube care and monitoring for migration or biofilm. PubMedLippincott
Dacryocystorhinostomy (DCR) (if the downstream nasolacrimal duct is blocked and proximal anatomy is usable)
Procedure: Creates a new opening between lacrimal sac and nose (external or endoscopic), sometimes with stents.
Why it’s done: Restores drainage when the sac/duct is the main bottleneck and at least one punctum/canaliculus is functional.

Surgical choice depends on what anatomy exists. In many patients with punctal atresia, the canaliculi behind the missing opening are also absent; in such cases, CDCR with a Jones tube is frequently required. PubMed

Preventions

Congenital punctal atresia is not preventable—it happens during fetal development. What is preventable is worsening of ocular surface irritation and some acquired scarring problems.

Protect eyes from chemical/thermal injuries (goggles for work/cleaning).
Treat blepharitis/meibomian gland dysfunction early to reduce chronic lid inflammation.
Control allergies and avoid smoke/irritants to limit chronic rubbing.
Use preservative-free eye products when frequent dosing is needed.
Don’t share eye makeup; replace it regularly to lower infection risk.
Manage skin conditions (rosacea, seborrheic dermatitis) that inflame eyelids.
Seek prompt care for conjunctival cicatrizing diseases (e.g., ocular cicatricial pemphigoid, SJS/TEN) to avoid scarring.
Discuss chemo/topical agents that may scar the lacrimal outflow (e.g., certain antimetabolites) and use protective measures when applicable.
Avoid excessive eye rubbing.
Maintain general wellness (sleep, hydration, nutrition) to support surface health.

When to see a doctor

Constant tearing from birth or early childhood.
A missing punctal opening you or your clinician cannot see at the inner lid margin.
Recurrent conjunctivitis, eyelid skin redness or crusting from wetness.
Light sensitivity, pain, or vision changes—urgent evaluation.
History of burns/trauma to lids or severe eye rashes (seek care promptly).
Tearing that interferes with reading, driving, or school/work.
Past surgery with persistent tearing despite treatment.
Any red-flag symptoms after procedures (fever, severe pain, pus).

What to eat” and “what to avoid”

What to eat more of

Water throughout the day for hydration.
Fatty fish (salmon, sardines) 2–3×/week for omega-3s.
Leafy greens (spinach, kale) for carotenoids and vitamin A precursors.
Colorful vegetables (carrots, bell peppers) for antioxidants.
Nuts/seeds (walnuts, chia, flax) for healthy fats and vitamin E.

What to limit/avoid

Tobacco smoke exposure (pro-inflammatory, tear-film toxic).
Excess alcohol (dehydrating, worsens surface irritation).
Very high-sugar ultra-processed foods (systemic inflammation).
Overuse of caffeinated/energy drinks if they worsen dryness (moderation).
Spicy/irritating foods before bedtime if they trigger reflux/irritation that disturbs sleep and ocular comfort.

Frequently asked questions

What exactly is punctal atresia?
It means the normal tear-duct opening on the lid margin never formed (or is completely sealed over), so tears can’t enter the drainage system and overflow onto the cheek. EyeWiki
How is it different from punctal stenosis?
Stenosis is a narrow opening that developed later (often from scarring) and can be enlarged; atresia is a missing opening from birth, often with missing canaliculi, and typically needs surgical creation of a pathway. EyeWikiNCBI
Can eye drops cure it?
No. Drops can soothe symptoms and protect the surface, but they can’t create a punctum.
Can massage open it in babies?
No—massage can help lower nasolacrimal duct obstruction, but it does not create a missing punctum.
How do doctors diagnose it?
A slit-lamp exam looks for a visible punctum; gentle probing/irrigation and sometimes imaging help define whether canaliculi or downstream ducts are present. A careful exam also rules out punctal stenosis and other causes of tearing. EyeWiki
Is it common to have other tear-drainage parts missing too?
Yes. Many patients with punctal atresia lack the canaliculus behind the missing opening, which affects the surgical plan. PubMed
What surgery is done if the canaliculus is absent?
A bypass called CDCR with a Jones tube is commonly used; it creates a new tear path from the eye to the nose. PubMed
Is three-snip punctoplasty useful here?
Three-snip is for stenosis (narrowed puncta), not for true atresia where no opening exists. PMC
Will surgery fix the problem permanently?
Surgery can markedly reduce tearing, but long-term care is needed—e.g., Jones tubes can migrate, crust, or need replacement. PubMed
Is it hereditary or linked to syndromes?
It can occur alone or, less commonly, with syndromes (e.g., ectodermal dysplasia variants). Genetics consultation may be considered when other features are present. PubMed+1
Does punctal atresia affect vision?
Usually vision is fine; the main complaint is tearing and irritation. (Vision can blur temporarily from tears.)
Are plugs an option?
Plugs help conserve tears in dry eye or stenosis but cannot be placed if the punctum is missing. EyeWiki
Are there “stem-cell drops” to regrow a punctum?
No. There are no approved stem-cell drugs for this. Some biologic therapies (like autologous serum) can help the ocular surface but not the drainage anatomy. PMC
What about diquafosol or rebamipide drops I read about?
These are mucin/tear secretagogues available in certain countries. They can improve dry-eye signs and symptoms but do not create a punctum; availability varies. PubMedPMC
What is recovery like after surgery?
Most minor procedures heal within 1–2 weeks. CDCR/Jones tube patients learn simple tube care. Your surgeon will schedule checks to ensure position and function. PubMed
