Understanding, Recognising, and Treating Tear Sac Infections at Blue Fin Vision® Eye Clinic
Dacryocystitis is a potentially serious infection of the tear (lacrimal) sac, most often caused by a blockage in the tear duct. At Blue Fin Vision® Eye Clinic, serving London, Chelmsford, and Hatfield, we combine advanced diagnostics, specialist expertise, and compassionate care to ensure the best outcomes for patients suffering from this uncomfortable and sometimes sight-threatening condition.
What is Dacryocystitis?
Dacryocystitis is an infection and inflammation of the lacrimal sac – the small reservoir near the inner corner of your eye that collects tears before they drain into the nose. This condition typically arises when the tear duct becomes blocked, preventing normal drainage and allowing bacteria to multiply within the sac.
Dacryocystitis Causes
A blocked tear duct is the most common underlying cause of dacryocystitis. When tears cannot drain away as they should, they stagnate in the lacrimal sac, creating an ideal environment for bacteria to grow and cause infection. Key causes include:
- Congenital blockage: Some people are born with narrow or obstructed tear ducts.
- Age-related narrowing: Tear ducts can become narrower with age, increasing the risk of blockage.
- Chronic sinus or nasal disease: Conditions such as sinusitis can contribute to duct obstruction.
- Facial trauma or injury: Damage to the nose or surrounding structures can disrupt tear drainage.
- Nasal or facial surgery: Previous procedures may alter the anatomy of the tear drainage system.
- Inflammatory conditions: Chronic inflammation of the nasal passages or eyes can cause scarring and blockage.
Dacryocystitis Symptoms
Recognising dacryocystitis symptoms early is crucial for prompt treatment and to prevent complications. Common symptoms include:
- Redness and swelling at the inner corner of the eye, often extending onto the nose
- Pain or tenderness in the affected area
- Watery eye (excessive tearing)
- Pus or discharge from the inner corner of the eye
- Crusting of the eyelids, especially after sleep
- Fever or feeling generally unwell in severe cases
- Blurred vision (if the infection spreads or causes significant swelling)
If you experience these symptoms, especially if accompanied by fever or spreading redness, seek urgent assessment at a specialist eye clinic.
Dacryocystitis Treatment
At Blue Fin Vision® eye clinic, we offer a comprehensive approach to dacryocystitis treatment, tailored to the severity and underlying cause of your condition.
- Acute Management
- Antibiotics: Oral or intravenous antibiotics are prescribed to control infection. In some cases, antibiotic eye drops may also be used.
- Warm compresses: Applying gentle warmth to the area can help relieve discomfort and encourage drainage.
- Pain relief: Over the counter or prescribed painkillers may be recommended to manage discomfort.
- Drainage of Abscess
If an abscess (collection of pus) forms, a minor surgical procedure may be required to drain the infected material and relieve pressure. This is typically performed under local anaesthetic for your comfort.
- Addressing the Underlying Cause
To prevent recurrence, it is essential to treat the cause of the blocked tear duct. This may involve:
- Probing and irrigation: In some cases, a simple procedure to open the duct and flush out debris may be effective.
- Surgical intervention: Patients are referred for consideration of a procedure called dacryocystorhinostomy (DCR) after the first episode of dacryocystitis. This surgery creates a new drainage pathway for tears, bypassing the blockage and reducing the risk of future infections. Early surgical intervention can significantly reduce the risk of recurrent infections and long-term complications.
- Follow-Up Care
Regular follow-up appointments are important to monitor healing, ensure the infection has resolved, and assess tear duct function.
Why Prompt Dacryocystitis Treatment Matters
Untreated dacryocystitis can lead to serious complications, including:
- Spread of infection to surrounding tissues (cellulitis)
- Orbital abscess (a deeper, potentially sight-threatening infection)
- Chronic tearing and discomfort
- Formation of fistulas (abnormal passages from the tear sac to the skin)
- Vision loss (in rare, severe cases)
Early diagnosis and expert management are essential for a full recovery and to protect your long-term eye health.
