Dacryocystitis (Tear Duct Infection)

If your baby has been diagnosed with or you suspect dacryocystitis (tear duct infection), here is what the evidence says.
The short answer
Dacryocystitis is an infection of the tear sac (lacrimal sac) located between the inner corner of the eye and the nose. It often develops as a complication of a blocked tear duct (nasolacrimal duct obstruction), which is common in infants. Signs include redness, swelling, and tenderness over the inner corner of the eye near the nose, along with yellow-green discharge and tearing. Dacryocystitis requires prompt medical treatment with antibiotics, as the infection can spread to surrounding tissues.
Key takeaways
- Dacryocystitis is an infection of the tear sac (lacrimal sac) located between the inner corner of the eye and the nose. It often develops as a complication of a blocked tear duct (nasolacrimal duct obstruction), which is common in infants. Signs include redness, swelling, and tenderness over the inner corner of the eye near the nose, along with yellow-green discharge and tearing. Dacryocystitis requires prompt medical treatment with antibiotics, as the infection can spread to surrounding tissues.
- Usually normal when: Your baby has mild tearing and occasional clear mucus from a blocked tear duct without redness or swelling
- Call your doctor if: There is a red, firm, tender swelling between the inner corner of the eye and the nose, as this indicates acute dacryocystitis requiring prompt antibiotic treatment
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-3 months
About 6-20% of newborns have a blocked tear duct, and a small percentage of these develop dacryocystitis. Signs include a firm, tender, red swelling between the inner corner of the eye and the nose. This is different from simple blocked tear duct symptoms (watery eyes and mild discharge). Acute dacryocystitis in newborns (dacryocystitis of the newborn or dacryocystocele) may present as a bluish swelling at birth and needs prompt evaluation.
3-6 months
If a blocked tear duct has not resolved and becomes infected, dacryocystitis can develop. Treatment typically includes oral antibiotics and warm compresses. Gentle lacrimal sac massage (Crigler massage) may help promote drainage. If the infection is severe or does not respond to antibiotics, the baby may need hospitalization for intravenous antibiotics.
6-12 months
If a blocked tear duct persists and recurrent dacryocystitis occurs, a probing procedure to open the blocked duct may be recommended, typically performed between 6 and 12 months of age. The probing is done under brief anesthesia and has a high success rate (about 90%). This prevents future episodes of dacryocystitis.
12 months+
If probing has not been performed and the blocked duct persists, the risk of recurrent dacryocystitis continues. After age 12 months, the success rate of simple probing decreases, and more advanced procedures such as balloon dacryoplasty or silicone tube intubation may be needed. Chronic or recurrent dacryocystitis should be managed by a pediatric ophthalmologist.
What Should You Do?
When to take action
- Your baby has mild tearing and occasional clear mucus from a blocked tear duct without redness or swelling
- Gentle tear duct massage and warm compresses are keeping symptoms manageable
- The blocked tear duct symptoms are improving on their own over time
- Your baby's eye has mild crusting in the morning but the area is not red, warm, or swollen
- Discharge from the eye has become yellow or green and thicker than before
- You notice persistent redness at the inner corner of the eye near the nose
- The blocked tear duct has not resolved by 6 months and you want to discuss probing
- There is a red, firm, tender swelling between the inner corner of the eye and the nose, as this indicates acute dacryocystitis requiring prompt antibiotic treatment
- The swelling is spreading to the eyelid, cheek, or forehead, or your baby has a fever, which could indicate the infection is spreading and may require urgent care or hospitalization

Bottom line
Most cases of dacryocystitis (tear duct infection) are normal. Talk to your pediatrician if there is a red, firm, tender swelling between the inner corner of the eye and the nose, as this indicates acute dacryocystitis requiring prompt antibiotic treatment.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Agenesis of the Corpus Callosum (ACC)
Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
