Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Symptoms — what the patient reports (2)

Infants have chronic or intermittent tearing with crusting on the eyelashes [crusting · eye discharge]
Overflow tearing and repeated eye rubbing can cause mild eyelid redness, though the conjunctiva itself is not typically red [dry eye · eye discharge · redness]

Signs — what you find (3)

The tear film along the lid margin is increased in volume
Pressing on the tear sac can push tears or mucous discharge back out through the puncta [eye discharge]
Acute infection of the tear sac shows swelling and redness with a distended sac below the inner corner of the eye, sometimes with fever and irritability [fever · irritability · redness]

Tests (2)

The dye disappearance test checks whether fluorescein dye clears from the eye within 5 minutes when the diagnosis is unclear
Diagnosis is usually made from history and physical exam alone, without further testing

If not this — what else fits (3)

Conjunctivitis, corneal abrasion, and uveitis are also on the differential list
The lack of other associated signs and symptoms helps separate this condition from other causes of persistent tearing
Referral to ophthalmology is warranted when the diagnosis is uncertain, especially with concern for glaucoma or an infected tear sac

NASOLACRIMAL MASSAGE AND EYELID HYGIENE (NO DRUG THERAPY)

1st line

Dose source

Congenital nasolacrimal duct obstruction - disease-level clinical article (congenital-nasolacrimal-duct-obstruction-clinical.txt)

Why

The article's first-line management is a manoeuvre and washing, not a prescription: massage over the nasolacrimal sac, as a rule 2 to 3 times a day, with the eyelids cleaned in warm water and a topical antibiotic alongside - a regimen that settles the symptoms in 76% to 89% of uncomplicated cases. Teaching the mother the massage is the intervention that carries the effect.

Cautions

HOW OFTEN - massage the tear duct 2 to 3 times a day as a rule, and clean the lids with warm water at the same time. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) Show the mother once in the clinic; a described massage is rarely done correctly at home.
WHAT TO EXPECT - a blocked tear duct present from birth clears by itself very often indeed: around 70% of these babies have no symptoms left by 3 months of age, and over 90% are better by their first birthday. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
By 6 months of age roughly 90% of infants with a congenital nasolacrimal duct obstruction (NLDO) have settled without treatment. Of those still symptomatic between 6 and 10 months, about two-thirds clear within the next 6 months. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) Time is the main treatment.
Under 6 months of age, managing it conservatively is what is usually done. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) Under 6 months, massage and cleaning, not probing.
A bland ointment is for the skin, not the eye: where the skin has become macerated, a bland ophthalmic ointment can go on the lids. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
NO ANTIBIOTIC DROP IS PRINTED HERE. The article does say that a topical antibiotic is used to keep mucopurulent discharge in check (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873), but it names no agent, no strength and no frequency, so no dose claim can be quoted from any opened document and none is invented. Where a drop is genuinely wanted for purulent discharge, prescribe it from the bacterial conjunctivitis entry, which carries a sourced dose.
Most of these babies do not have conjunctivitis. A red conjunctiva is not part of the picture, though the tears running over, and the constant rubbing, may leave the lids somewhat red above and below. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) A white eye with a wet lash line is a blocked duct, not an infection.

REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)

Dose source

Congenital nasolacrimal duct obstruction - disease-level clinical article (congenital-nasolacrimal-duct-obstruction-clinical.txt)

Why

Carries the two situations the article does not leave with massage - acute dacryocystitis and the diagnoses that mimic a watering eye - plus the age at which a persisting block becomes an ophthalmology problem.

Cautions

RED FLAG - ACUTE DACRYOCYSTITIS: a few newborns with a blocked duct present in the first weeks of life with something far worse - an acute dacryocystitis. You will see swelling and redness, with the lacrimal sac distended just below the medial canthal tendon, and the baby may be systemically unwell with fever and irritability. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
WHY IT MATTERS - acute dacryocystitis can go on to preseptal or orbital cellulitis, to sepsis, or to meningitis, and it is treated promptly with systemic antibiotics. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) That is a systemic antibiotic and an urgent referral, not a drop.
SEQUENCE IF INFECTED - where infection or cellulitis is present alongside, the systemic antibiotics come first and the probing afterwards. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
REFER - send the baby to an ophthalmologist where the diagnosis is in doubt, and particularly where glaucoma is a worry, or where there is any sign of dacryocystitis or of a dacryocystocele. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) A large, cloudy or photophobic eye is infantile glaucoma until an ophthalmologist says otherwise.
TIMING OF PROBING - where it has not settled by 6 to 10 months of age, paediatric ophthalmology probes the duct (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873), and a blockage still there past 12 months of age will probably need probing. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873) A baby still weeping at 10 months has an appointment to make.
THE DIFFERENTIAL - it is a wide one: conjunctivitis, an abrasion of the cornea, uveitis, haemangiomas, dermoids, nasal gliomas, and infantile glaucoma. What sets a congenital nasolacrimal duct obstruction (NLDO) apart from the other causes of a persistently watering eye is that nothing else accompanies it. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
REASSURE THE FAMILY THEY ARE IN THE RIGHT PLACE - most babies with a congenital NLDO can be diagnosed and managed in primary care. (Nasolacrimal Duct Obstruction - StatPearls - NCBI Bookshelf, NBK532873)
