Summary: Dacryocystitis is an infection of the tear sac, known as the lacrimal sac, located near the inner corner of the eye. This condition typically develops when the tear duct becomes blocked, allowing bacteria to multiply. Understanding dacryocystitis symptoms, causes, and available dacryocystitis treatment options is essential to prevent complications and protect eye health.

What is Dacryocystitis Surgery?
Dacryocystitis is an infection of the tear sac (lacrimal sac), which is part of the tear drainage system. Tears, produced by the lacrimal glands under the upper eyelids, help keep the eyes clean and lubricated. After washing over the eye surface, tears drain through small openings called puncta into the tear sac and then into the nasal cavity. When the tear duct becomes blocked, tears stagnate, allowing bacteria to grow inside the sac, leading to dacryocystitis eye infection.
Dacryocystitis Signs and Symptoms
The condition may appear suddenly (acute dacryocystitis) or develop slowly over time (chronic dacryocystitis). Common dacryocystitis symptoms include:
- Redness, pain, and swelling at the inner corner of the eye
- Watery eye or teary eye
- Tenderness and swelling next to the nose
- Eye redness and irritation
- Discharge of pus or mucus
- Fever in severe cases
Chronic dacryocystitis causes milder symptoms such as tearing and occasional discharge, with little or no swelling.
Acute Dacryocystitis vs Dacryoadenitis
While both conditions involve inflammation in the tear system, they affect different structures:
- Dacryocystitis affects the tear sac (lacrimal sac).
- Dacryoadenitis affects the lacrimal gland that produces tears.
Recognising this distinction is key for accurate diagnosis and targeted dacryocystitis treatment in adults and children.
Dacryocystitis Causes
A dacryocystitis cause is most often a blockage in the tear duct, leading to bacterial buildup. Contributing factors include:
- Injury to the nose or eye
- Sinus inflammation or infection
- Growths such as nasal polyps
- Foreign objects lodged in the tear duct
- Previous nasal or sinus surgery
- Tumours or cancer near the duct
- Congenital tear duct blockage in infants (congenital dacryocystitis)
Risk Factors:
- Ageing (tear ducts narrow with age)
- Female gender (naturally narrower ducts)
- Deviated nasal septum
- Chronic sinusitis or rhinitis
- Swelling of nasal structures (turbinate hypertrophy)
Dacryocystitis Treatment
The primary dacryocystitis treatment aims to eliminate infection and prevent recurrence. Depending on severity, your ophthalmologist may recommend:
- Medications:
Antibiotics to fight bacterial infection (oral or topical). Antibiotic eye drops or ointments to relieve pain and swelling.
- Surgery (for chronic or recurring cases):
After the infection subsides, patients may need a dacryocystorhinostomy (DCR) – a procedure that creates a new drainage pathway from the lacrimal sac to the nasal cavity.
This oculoplasty procedure helps bypass the blockage and restore normal tear flow. Dacryocystitis treatment in adults often includes DCR to prevent future infections.
- Home care:
- Apply warm compresses to reduce swelling.
- Maintain eyelid hygiene to prevent bacterial buildup.
- Dacryocystitis in Adults vs Children
- Adults: Most cases result from age-related narrowing of the tear duct or nasal inflammation.
- Children (Congenital Dacryocystitis): Babies may be born with blocked tear ducts, causing persistent tearing and discharge. Early evaluation ensures timely dacryocystitis treatment and prevents complications.
When to See a Doctor?
Seek immediate medical from your eye specialists if you experience:
- Persistent swelling or pain near the inner eye corner
- Pus or blood-stained discharge
- Fever or spreading redness
- Repeated tear duct infections
Ignoring dacryocystitis signs and symptoms can lead to complications such as abscess formation, orbital cellulitis, or vision impairment.
Why Timely Treatment Matters?
Prompt diagnosis and treatment of dacryocystitis eye infection prevent serious consequences. Advanced clinics, such as Centre for Sight, offer comprehensive management – from medical therapy to dacryocystorhinostomy (DCR) surgery – for effective, long-term results.
FAQs
Is dacryocystitis an emergency?
Yes, dacryocystitis can be a medical emergency, especially in acute cases with pain, swelling, fever, or pus discharge. If untreated, the infection can spread to surrounding tissues, causing orbital cellulitis or abscess formation. Prompt medical evaluation and dacryocystitis treatment with antibiotics or surgery are essential to prevent complications.
Can dacryocystitis cause blindness?
While dacryocystitis rarely causes blindness directly, severe or untreated infections can spread to the orbit or bloodstream, potentially leading to vision-threatening conditions like orbital cellulitis or endophthalmitis. Early treatment with antibiotics and, if necessary, dacryocystorhinostomy (DCR) surgery helps preserve eye health and prevent permanent visual damage.
What is the difference between acute and chronic dacryoadenitis?
Acute dacryoadenitis is a sudden inflammation of the lacrimal gland, usually caused by bacterial or viral infections, leading to pain, redness, and swelling in the upper outer eyelid. Chronic dacryoadenitis, on the other hand, develops slowly, often due to autoimmune diseases like sarcoidosis or thyroid disorders, with milder symptoms.
What are the three stages of dacryocystitis?
The three stages of dacryocystitis include:
- Congestive stage – Blockage causes tear stagnation and mild swelling.
- Acute stage – Active infection develops with redness, pain, and pus discharge.
- Chronic stage – Persistent tearing, recurrent infection, and duct fibrosis, often requiring surgical dacryocystitis treatment like DCR surgery.
What is the meaning of dacryocystitis?
Dacryocystitis meaning: It is an infection of the lacrimal (tear) sac, typically caused by a blockage in the tear duct. The condition leads to redness, swelling, and discharge near the inner corner of the eye. Timely dacryocystitis treatment prevents complications and restores normal tear drainage.
What is the difference between dacryocystitis and dacryostenosis?
Dacryocystitis is an active infection of the tear sac, caused by bacterial buildup due to duct blockage. Dacryostenosis, however, refers to the narrowing or partial obstruction of the tear duct without infection. While dacryostenosis can lead to dacryocystitis, early management can prevent progression to infection.
