Congenital Absence of the Lacrimal Puncta and Salivary Glands

Congenital absence of the lacrimal puncta and salivary glands means a baby is born without one or both tiny tear openings on the eyelid edge (the lacrimal puncta) and without some or all of the major salivary glands (parotid, submandibular, or sublingual) that make saliva. Missing puncta stop tears from draining, so tears can pool on the eye or spill over the lid. Missing salivary glands reduce or stop saliva production, causing a persistently dry mouth. These problems can occur alone or together and may be part of a genetic syndrome such as LADD (lacrimo-auriculo-dento-digital) or ALSG (aplasia of lacrimal and salivary glands). EyeWiki+2PMC+2

Congenital absence of the lacrimal puncta means a baby is born without the tiny tear-drain holes on the eyelid margins. Congenital absence (aplasia) of the salivary glands means the big spit glands (parotid, submandibular, sublingual) did not develop. Some children have both together. Doctors often call the combined problem “aplasia of lacrimal and salivary glands (ALSG).” ALSG is usually inherited in an autosomal dominant pattern and is most often linked to mutations in the FGF10 gene. Children may have very dry eyes (alacrima) and very dry mouth (xerostomia), early dental decay, and tearing problems because the tear drains are missing. ALSG overlaps with LADD (lacrimo-auriculo-dento-digital) syndrome. Monarch Initiative+3PubMed+3Nature+3

What actually happens in the body

If puncta and canaliculi are missing, tears cannot drain into the nose. This can cause watering (epiphora), infections, or inflammation. Many eyes with absent puncta also lack the canalicular channels, so simple punctal surgery will not work and a bypass tube (Jones tube) is often needed. On the mouth side, if major salivary glands never formed, saliva flow is very low. That causes rampant cavities, mouth soreness, fungal infections, taste change, trouble chewing and swallowing, and gum disease. Early prevention and lifelong tooth care are essential. ejomr.org+3PubMed+3ScienceDirect+3

During early embryo development, surface tissues that form the tear drainage openings and the salivary glands do not develop fully. The result can be complete absence (agenesis/aplasia) or underdevelopment (hypoplasia). ScienceDirect+1

Symptoms

1. Watery eyes (epiphora) because tears cannot drain through missing puncta. The eye may look “always teary.” EyeWiki

2. Mucous discharge or crusting from tear stagnation and surface irritation. EyeWiki

3. Recurrent inner-corner redness or infection (e.g., dacryocystitis later in life if downstream obstruction exists). NCBI

4. Photophobia or irritation since stagnant tears and surface dryness can make the eye light-sensitive. ScienceDirect

5. Skin maceration on the lower lid/cheek from constant tearing. ScienceDirect

6. Persistently dry mouth (xerostomia) when major salivary glands are absent. Frontiers

7. Difficulty chewing and swallowing dry foods because saliva is too low. Frontiers

Diagnostic tests

A) Physical examination

1. Eyelid margin inspection – the clinician gently everts the lid and looks for the punctal opening; true absence suggests canalicular agenesis too. PubMed

2. Slit-lamp biomicroscopy – checks ocular surface, tear meniscus, and inner canthus for signs of overflow, irritation, or infection. ScienceDirect

3. Fluorescein dye disappearance observation – a drop of dye is placed; if dye doesn’t clear, drainage is impaired (common in punctal agenesis). ScienceDirect

4. Oropharyngeal and oral exam – dry, sticky mucosa, lack of saliva pooling, and dental caries point toward salivary aplasia. AAPD

5. Gland palpation – parotid and submandibular areas may feel flat/absent; sometimes other glands look enlarged to compensate. SpringerOpen

6. Craniofacial screening – look for limb, ear, dental, or facial differences suggesting LADD/EEC/Treacher Collins. MedlinePlus+2EyeWiki+2

7. Dental evaluation – early tooth decay and enamel wear flag chronic dry mouth from gland aplasia. PubMed

B) Manual/office tests

8. Probing/irrigation attempt – in typical obstruction, a probe can pass through puncta; in agenesis, puncta/canaliculi may not exist, confirming the anatomical absence. PubMed

9. Schirmer tear test – a paper strip measures tear production; a normal or high value with poor clearance points toward outflow absence rather than low production. ScienceDirect

10. Jones tests (primary/secondary) – dye-based checks of tear passage into the nose; failure supports drainage absence or severe atresia. ScienceDirect

11. Unstimulated sialometry – timed saliva collection (e.g., 15 minutes) quantifies baseline flow; extremely low flow supports major gland aplasia. AAPD

12. Stimulated sialometry (e.g., with citric acid) – measures the capacity of any residual gland tissue; absent rise suggests true aplasia. AAPD

13. Gustatory stimulation observation – tasting sour normally boosts saliva; little/no response supports aplasia. AAPD

C) Laboratory & pathological tests

14. Genetic testing panel – assays for FGF10, FGFR2, FGFR3 when LADD/ALSG is suspected or there’s a family pattern. Results guide counseling. PMC+1

15. Autoimmune screen (SSA/SSB, ANA) where needed – helps rule out acquired causes of dry mouth/eye (e.g., Sjögren), ensuring the dryness is congenital in origin. WJGnet

16. Oral swab or culture for candidiasis – dry mouth predisposes to yeast overgrowth; positive results support complications of low saliva. WJGnet

17. Minor salivary gland biopsy (selected cases) – pathology can show absence/hypoplasia if glands are missing or rudimentary; used when diagnosis remains unclear. PMC

D) Electrodiagnostic

18. Electrogustometry – applies tiny electrical currents to the tongue to quantify taste thresholds; abnormal results reflect taste pathway function, which depends on saliva and cranial nerve integrity. NCBI+1

19. Blink (corneal) reflex EMG study – measures the reflex arc (CN V–VII) controlling blinking; mainly used for neurological questions, but it documents the reflex pathway that also supports tear protection. NCBI+1

20. Bedside corneal reflex test – gentle corneal touch should trigger a blink; absence calls for careful ocular surface protection and sometimes formal EMG evaluation. NCBI

E) Imaging tests

21. High-resolution orbital imaging (CT/MRI) – maps the lacrimal drainage region when anatomy is uncertain; modern MRI can outline the pathway non-invasively. NCBI

22. Magnetic resonance dacryocystography (MRD) – uses heavily T2-weighted MRI to show tear passages without contrast; emerging data suggest accuracy close to conventional methods. IOVS

23. Conventional dacryocystography – contrast X-ray of the drainage system; long considered the “gold standard” for obstructive patterns (not possible if the puncta/canaliculi are absent). Radiopaedia

24. Ultrasound of major salivary regions – quick, noninvasive check; absent glands won’t be visualized. Lippincott Journals

25. MRI of salivary glands – confirms absence of parotid/submandibular/sublingual glands and shows any compensatory hypertrophy of remaining tissue. PMC+1

26. CT of salivary spaces – helpful overview in complex cases or when MRI is unavailable. SpringerOpen

27. MR sialography – heavily T2-weighted sequences visualize ducts without cannulation; useful when ducts exist but are small. AJNR

28. Nuclear medicine salivary scintigraphy (99mTc pertechnetate) – shows functional uptake/excretion; absent uptake supports aplasia. Lippincott Journals

Non-pharmacological treatments (therapies & other measures)

1) Preservative-free artificial tears and lubricating gels
These are the first line for dry eye symptoms. Preservative-free drops reduce toxicity from benzalkonium chloride in frequent users. Use as often as needed in the day; thicker gels or ointments at night protect the cornea. Purpose: comfort, protect the ocular surface, and improve vision fluctuations. Mechanism: they replace part of the aqueous layer and slow evaporation; gels/ointments increase residence time on the cornea. In people with no puncta, plugs do not apply, so surface replacement is key. Choose carboxymethylcellulose, hyaluronate, or glycerin bases based on comfort. Regular use lowers friction, staining, and blinking pain. tearfilm.org

2) Eyelid hygiene and warm compresses
Simple lid scrubs and warm compresses help meibomian glands make better oil, which slows tear evaporation. Purpose: reduce eyelid inflammation and stabilize the tear film. Mechanism: warmth liquefies meibum; gentle massage expresses oil; hygiene cuts bacterial load and toxins. Better lipid quality improves tear break-up time and reduces burning. This is safe, cheap, and useful in almost all dry eye patients, including those with absent puncta. Consistency matters (daily routines). tearfilm.org

3) Moisture chamber glasses and environmental control
Wrap-around moisture goggles trap humidity around the eyes and reduce airflow shear. Purpose: reduce evaporation and wind exposure. Mechanism: they create a small humid micro-environment and reduce tear film stress. At home and work, add humidifiers, avoid fans directed at the face, and take blinking breaks from screens to reduce digital eye strain. These simple steps can meaningfully cut symptoms without medicines. tearfilm.org

4) Scleral lenses (including PROSE therapy)
Large-diameter, fluid-filled scleral lenses vault the cornea and sit on the white of the eye. Purpose: constant liquid bandage over the cornea to relieve pain and improve vision when drops are not enough. Mechanism: a reservoir of sterile saline under the lens bathes the surface all day, reduces exposure, and smooths irregularities. Studies show improved comfort, surface staining, and function in severe ocular surface disease. They are powerful for people with severe dryness and no drain openings. PMC

5) Autologous serum tears (AST) or platelet-rich plasma tears
These are made from the patient’s own blood serum and contain growth factors, vitamin A, and other epitheliotropic nutrients. Purpose: heal and stabilize the corneal surface in severe dry eye. Mechanism: they mimic natural tear trophic factors that artificial tears lack. Randomized and controlled studies support symptom and staining improvements in severe disease. They are particularly helpful when standard drops fail. PubMed

6) Submandibular or minor salivary gland transplantation for extreme ocular dryness
For the most severe, refractory ocular surface disease, teams can transplant a salivary gland (usually submandibular) to provide continuous lubrication to the eye, or graft labial minor glands into the fornix. Purpose: replace missing lacrimal function with salivary secretion. Mechanism: transplanted gland secretes saliva (saliva tears) into the conjunctival sac, improving Schirmer scores and surface health for years. Modern series and meta-analyses show sustained improvement, though there are risks (viscous tears, duct obstruction). This is specialized surgery reserved for advanced cases. PMC+2Ajo+2

7) Dental caries prevention program (fluoride, sealants, xylitol gum as tolerated)
People without salivary glands get cavities fast. Build a strict prevention plan: high-fluoride toothpaste twice daily, in-office fluoride varnish, and sealants on vulnerable teeth. Purpose: lower caries risk when saliva is absent. Mechanism: fluoride promotes remineralization and makes enamel more acid-resistant; sealants block fissures. Evidence supports fluoride varnish for caries prevention; xylitol gum can reduce cariogenic bacteria for some patients, though adult trial results are mixed. PMC+2Cochrane+2

8) Saliva substitutes (sprays, gels, lozenges) and frequent water sipping
Commercial saliva substitutes (e.g., carboxymethylcellulose gels, mucin-like agents) provide temporary moisture and lubrication. Purpose: ease talking, chewing, and swallowing, and reduce mouth soreness. Mechanism: they coat the mucosa and lower friction. They are safe to use as often as needed. Carry a water bottle and take small sips during the day. ClinicalTrials.gov

9) Sugar-free diet, avoid acidic drinks, structured meal timing
Without saliva, sugar and acid quickly damage enamel. Purpose: limit acid attacks and lower bacterial fuel. Mechanism: cutting sugar frequency lowers Streptococcus mutans activity; avoiding sodas/juices lowers erosive wear. Combine with chewing sugar-free gum (prefer xylitol if tolerated) to stimulate any residual saliva and neutralize acids. PMC+1

10) Professional dental recalls every 3 months
Shorter recall intervals let dentists apply fluoride, catch early lesions, and manage fungal infections. Purpose: protect teeth and mucosa long-term. Mechanism: frequent topical fluoride and early restoration prevent catastrophic caries progression typical of xerostomia. ClinicalTrials.gov

11) Manage oral candidiasis promptly
Dry mouth increases Candida infections. Purpose: relieve soreness/burning and prevent angular cheilitis. Mechanism: topical antifungals (as needed and prescribed) reduce fungal load; meticulous denture hygiene lowers recurrence. Prevention plus early treatment improves comfort and nutrition. ClinicalTrials.gov

12) Speech and swallow therapy when chewing/swallowing is hard
Therapists teach safe-swallow techniques and diet texture adjustments. Purpose: maintain nutrition and avoid aspiration. Mechanism: compensatory strategies, pacing, and moisture control help with bolus formation when saliva is absent. ClinicalTrials.gov

13) Screen, educate, and involve genetics
Offer genetic counseling for ALSG/LADD families. Purpose: explain inheritance, testing options, and future pregnancy risks. Mechanism: FGF10 mutations are a known cause; counseling supports informed decisions and early child screening. PubMed

14) Eye protection outdoors and during sleep
Use wrap-around sunglasses by day and sleep masks or moisture shields at night. Purpose: cut evaporation and particle irritation. Mechanism: barrier effect lowers tear film stress and morning pain. tearfilm.org

15) Computer vision hygiene (20-20-20 rule)
Every 20 minutes, look 20 feet away for 20 seconds and blink fully. Purpose: reduce digital-induced evaporative stress. Mechanism: increases blink rate and meibomian lipid spread. tearfilm.org

16) Treat eyelid inflammation (blepharitis) non-pharmacologically
Lid warming/scrubs reduce biofilm and Demodex burden; tea-tree-oil cleansers may help (as advised by your clinician). Purpose: improve tear stability indirectly. Mechanism: cleaner lids → better meibum → slower evaporation. tearfilm.org

17) Consider punctal surgery only when applicable
In congenital agenesis, puncta and canaliculi are often absent, so punctoplasty is not helpful. If imaging or OCT shows a canaliculus behind a membrane, selected cases might benefit. Most bilateral agenesis need a bypass (Jones tube). Purpose: set realistic expectations and avoid ineffective procedures. Mechanism: surgery tailored to anatomy. PubMed+1

18) Conjunctivodacryocystorhinostomy (CDCR) with Lester-Jones tube
This is the standard bypass when canaliculi are absent. Purpose: create a new route from the eye to the nose. Mechanism: a glass or Medpor-coated tube shunts tears to the nasal cavity, reducing epiphora. Success is high with experienced surgeons, but tubes need maintenance. ScienceDirect+1

19) Home and work safety (hydration, cool environment)
Sweating risk increases if later you use muscarinic medicines for saliva. Even without medicines, dehydration worsens symptoms. Purpose: keep body water up and reduce heat stress. Mechanism: steady oral intake and cool rooms prevent extra eye and mouth dryness. Cleveland Clinic

20) Psychosocial support and adherence coaching
Severe dryness affects sleep, mood, and social eating. Purpose: support coping and daily habit building (drops, gels, dental care). Mechanism: structured routines and support groups improve quality of life in chronic dry eye/dry mouth. Frontiers

Dietary molecular supplements

1) High-fluoride toothpaste (5,000 ppm) nightly
Dose: pea-sized amount at bedtime; spit, do not rinse. Function: enamel remineralization and caries resistance when saliva is absent. Mechanism: fluoride integrates into enamel crystals and slows demineralization. Evidence supports caries reduction in high-risk groups. PMC

2) In-office fluoride varnish (2–4×/year)
Dose: dentist-applied. Function: strong, sustained fluoride reservoir. Mechanism: varnish binds enamel and releases fluoride slowly. Cochrane reviews report sizable caries-inhibiting effects, especially at high risk. Cochrane

3) Silver diamine fluoride (SDF) for root/cervical lesions
Dose: professional application per lesion. Function: arrests and prevents root caries, common in xerostomia. Mechanism: silver is antimicrobial; fluoride remineralizes. Evidence suggests benefit for root surfaces in adults. Cochrane

4) Xylitol (gum/lozenges) if tolerated
Dose: often 5–10 g/day in divided uses. Function: reduces cariogenic bacteria and acid production. Mechanism: non-fermentable polyol disrupts S. mutans metabolism. Evidence in adults is mixed; some trials show limited benefit. Avoid if GI upset. PMC+1

5) Saliva substitute gels with carboxymethylcellulose
Dose: PRN, especially at night. Function: lubricate oral mucosa. Mechanism: viscous coating reduces friction and microtrauma. Improves comfort and speech. ClinicalTrials.gov

6) Neutral sodium fluoride mouthrinse (daily or weekly)
Dose: per dental plan. Function: extra anti-caries protection between varnishes. Mechanism: topical fluoride exposure maintains remineralization. ScienceDirect

7) Vitamin A in autologous serum tears (delivered locally)
Dose: via AST, not oral supplementation. Function: supports goblet cells and epithelium. Mechanism: trophic factors in serum tears improve epithelial health beyond plain lubricants. PubMed

8) Omega-3 fatty acids (considered optional)
Dose: often 1–3 g/day EPA+DHA used in studies. Function: theoretical anti-inflammatory effect. Mechanism: eicosanoid modulation. Large DREAM trial found no significant benefit versus placebo; smaller studies vary. Discuss risks and expectations. New England Journal of Medicine+1

9) Remineralizing pastes (e.g., CPP-ACP) as adjuncts
Dose: apply nightly as directed. Function: add calcium/phosphate to enamel surface. Mechanism: stabilize ions to support remineralization in dry mouth. Use as an adjunct to high-fluoride care. ClinicalTrials.gov

10) Alcohol-free antiseptic rinses (short courses)
Dose: as advised to limit burn/irritation. Function: reduce plaque when mechanical cleaning is hard due to soreness. Mechanism: lowers microbial load, supporting caries prevention. Avoid chronic use if it worsens dryness. ClinicalTrials.gov

Immunity-booster / regenerative / stem-cell-oriented” drugs

(Each ≈100 words; these are specialist options and not routine.)

1) Autologous serum tears (biologic tear) for ocular surface repair
Mechanism: patient-derived growth factors (EGF, vitamin A) promote epithelial healing and nerve health. Function: reduces pain, staining, and filaments in severe disease. Dose: usually 20–50% serum drops QID–Q6/day. PubMed

2) Platelet-rich plasma (PRP) eye drops
Mechanism: concentrated platelet growth factors (PDGF, TGF-β) support regeneration. Function: used off-label for severe keratopathy when other therapy fails. Dose: clinic-prepared, dosing like AST. PubMed

3) Submandibular gland transplantation (microvascular)
Mechanism: transplanted gland provides long-term “salivary tears.” Function: improves Schirmer, staining, and quality of life for many years. Dose: one-time surgery, long follow-up. Ajo+1

4) Minor salivary gland transplantation (labial grafts)
Mechanism: labial glands secrete mucinous saliva into the fornix. Function: improves symptoms, TBUT, and ocular surface in severe dry eye; newer meta-analysis shows 70%+ improvement rates. Dose: surgical grafting, with tailored care. Lippincott Journals

5) Biologic anti-inflammatories under study for dry eye
Mechanism: novel pathways (e.g., aldehyde traps like reproxalap) aim to quell inflammation; however, not all succeed. Function: highlight that evidence must be strong before use. Dose: investigational—not routine care. Reuters

6) Nerve-stimulation approaches (varenicline nasal route)
Mechanism: stimulates trigeminal-parasympathetic arc to boost natural tears. Function: restores basal tear film without ocular drop preservatives. Dose: 0.03 mg each nostril BID. FDA Access Data

Surgeries

1) Conjunctivodacryocystorhinostomy (CDCR) with Lester-Jones tube
Procedure: a small channel from eye to nose with a glass/Medpor tube to bypass missing canaliculi. Why: definitive option when puncta/canaliculi are absent; reduces epiphora. Success is high with expert care. ScienceDirect

2) Endoscopic or external DCR (selected single-punctum cases)
Procedure: create a window from lacrimal sac to nose. Why: in patients with one present punctum and nasolacrimal duct obstruction, DCR treats distal blockage. In pure agenesis of both puncta, DCR alone is not enough. ScienceDirect

3) Punctoplasty (only when a canaliculus exists behind an atretic membrane)
Procedure: open the punctum and enlarge it. Why: if imaging/OCT shows a canaliculus, punctoplasty can restore drainage. In true agenesis without canaliculi, it will not work. UCL Discovery

4) Submandibular gland transplantation (for ocular surface)
Procedure: microvascular transfer of the submandibular gland with duct to the eye region. Why: severe, refractory dry eye needing continuous lubrication. Long-term improvements reported. Ajo

5) Minor salivary gland transplantation (labial)

When to see doctors (red flags)

See an ophthalmologist urgently if you have sharp eye pain, light sensitivity, vision drop, or a non-healing corneal erosion—these can threaten sight in severe dryness. Seek oculoplastic evaluation if tearing is constant and eyelashes and inner eye are always wet despite surface therapy—this suggests you may need a drainage bypass. See a dentist/oral medicine specialist promptly for new mouth ulcers, burning, white plaques (possible thrush), or sudden surge in cavities. Ask about genetic counseling if multiple family members have dry eyes/mouth from childhood. PubMed+3PubMed+3ScienceDirect+3

What to eat & what to avoid

1. Eat dairy or calcium-rich foods; purpose: support teeth. Avoid frequent sugary snacks. PMC

2. Eat soft, moist foods with broths or sauces; avoid dry crackers/meats without fluids. ClinicalTrials.gov

3. Use sugar-free gum/lozenges (xylitol if tolerated) after meals; avoid hard candies with sugar. PMC

4. Drink water often; avoid acidic sodas/juices and alcohol mouthrinses. PMC

5. Include omega-3 foods if you like them; note: supplements have mixed evidence for dry eye and are optional. New England Journal of Medicine

6. Choose neutral pH beverages; avoid frequent lemon or vinegar drinks. ClinicalTrials.gov

7. Add moist sides (yogurt, stews) to meals; avoid very spicy or salty foods that sting. ClinicalTrials.gov

8. Use fluoride toothpaste nightly; avoid immediate rinsing after brushing. PMC

9. Consider remineralizing pastes as adjuncts; avoid grazing on sweets. ClinicalTrials.gov

10. Limit caffeine and alcohol if they worsen dryness; monitor personal response. ClinicalTrials.gov

FAQs

1) Is ALSG the same as LADD syndrome?
They overlap. ALSG focuses on lacrimal/salivary aplasia; LADD adds ear, tooth, and digit changes. Both can involve FGF10 pathway variants. PubMed

2) If my puncta are missing, can simple punctal surgery fix tearing?
Often no. Most eyes with absent puncta also lack canaliculi; a bypass tube (Jones tube) is usually needed. PubMed

3) Are scleral lenses safe?
With training and hygiene, they are very helpful for severe ocular surface disease and can improve comfort and vision. PMC

4) Do omega-3 pills cure dry eye?
Large RCTs (DREAM) did not show clear benefit over placebo; some smaller studies are mixed. They’re optional, not core therapy. New England Journal of Medicine

5) Can pilocarpine or cevimeline help if my salivary glands never formed?
These work only if some gland tissue remains. In complete aplasia, benefit is limited. They also have side effects (sweating, risk in asthma/glaucoma). FDA Access Data+1

6) Why do I get cavities so fast?
Saliva protects teeth. Without it, acids and bacteria damage enamel rapidly. Intensive fluoride care prevents damage. PMC

7) Are there surgeries to give me “tears”?
Yes. Submandibular or minor salivary gland transplantation can supply “salivary tears” for severe cases. Ajo+1

8) What is a Jones tube?
It is a small tube that carries tears from the eye to the nose when natural drains are missing. ScienceDirect

9) How fast do cyclosporine or lifitegrast work?
They reduce inflammation over weeks; many people notice improvement between 4–12 weeks. ScienceDirect+1

10) Are there new drugs coming?
Some candidates fail approval (for example, reproxalap). This is why established therapies are preferred. Reuters

11) Can a humidifier really help?
Yes. Higher room humidity lowers evaporation and improves comfort. tearfilm.org

12) Do I need genetic testing?
It is optional but useful when there is a family pattern or syndromic features. Counseling explains pros/cons. PubMed

13) Will punctal plugs help me?
No—plugs block puncta. In agenesis, puncta do not exist, so plugs are not an option. Focus on surface therapy or bypass surgery when appropriate. PubMed

14) Can I wear contact lenses?
Standard soft lenses are often uncomfortable. Scleral lenses are better for severe dryness because they bathe the eye in fluid. PMC

15) What is the single most important dental step?
Nightly 5,000-ppm fluoride toothpaste and regular varnish. It protects teeth when saliva is absent. PMC
