Dacryocystitis: Causes and Treatments
Dacryocystitis occurs when the nasolacrimal duct is blocked, leading to the accumulation of tears and subsequent infection of the lacrimal sac. This blockage can be either acute or chronic and may occur in individuals of any age.
If left untreated, it can cause significant discomfort and may lead to more serious complications. Dacryocystitis is often associated with swelling, redness, and pain in the area near the inner corner of the eye, making it not only a medical concern but also a source of aesthetic discomfort.
Causes of Dacryocystitis
Dacryocystitis can be attributed to various causes, which can be broadly categorized into congenital and acquired factors:
Congenital Causes
- Nasolacrimal Duct Obstruction: This is the most common congenital cause of dacryocystitis in infants. It occurs when the nasolacrimal duct is not fully developed or is blocked by tissue.
- Anatomical Abnormalities: Some individuals may be born with structural abnormalities of the tear drainage system, leading to recurrent infections.
Acquired Causes
- Infections: Bacterial infections are the most common cause of dacryocystitis. Staphylococcus aureus and Streptococcus pneumoniae are frequently implicated pathogens.
- Inflammatory Conditions: Conditions such as sinusitis or rhinitis can lead to inflammation and obstruction of the nasolacrimal duct.
- Trauma or Injury: Physical injury to the face or nose can lead to scarring or narrowing of the duct.
- Age-Related Changes: As individuals age, the tissues around the nasolacrimal duct may lose elasticity, increasing the risk of blockage.

Get A Second OpinionRecognizing Dacryocystitis Symptoms
The symptoms of dacryocystitis can vary depending on whether the condition is acute or chronic:
Acute Dacryocystitis Symptoms
- Sudden Pain and Swelling: Acute dacryocystitis is often marked by sudden, intense pain and swelling near the inner corner of the eye.
- Redness and Warmth: The affected area may become red and feel warm to the touch.
- Discharge: There may be a purulent discharge from the tear duct.
- Fever: In some cases, a fever may accompany the infection.
Chronic Dacryocystitis Symptoms
- Persistent Tearing: Chronic dacryocystitis is characterized by ongoing tearing and a feeling of fullness near the inner eye.
- Recurrent Infections: Individuals may experience repeated episodes of infection and discomfort.
- Mild Discharge: While discharge may be present, it is often less severe than in acute cases.

Book an AppointmentDiagnosing Dacryocystitis
Accurate diagnosis of dacryocystitis typically involves a combination of clinical examination and diagnostic tests. An ophthalmologist or an ENT specialist is usually involved in the assessment:
- Clinical Examination: The healthcare provider will assess the symptoms and examine the eye and surrounding areas for signs of infection and blockage.
- Imaging Studies: Techniques such as dacryocystography or lacrimal scintigraphy may be used to visualize the tear drainage system and identify blockages.
- Cultures and Sensitivity Tests: Samples of discharge may be collected to identify the causative bacteria and determine the most effective antibiotics.
Treatment Options for Dacryocystitis
The treatment of dacryocystitis depends on the severity and underlying cause of the condition. Options range from conservative management to surgical intervention:
Medical Management
- Antibiotics: In cases of bacterial infection, antibiotics are the first line of treatment. The choice of antibiotic may be guided by culture and sensitivity results.
- Warm Compresses: Applying warm compresses to the affected area can help reduce swelling and promote drainage.
- Pain Management: Analgesics may be prescribed to alleviate pain and discomfort.
Surgical Interventions
- Dacryocystorhinostomy (DCR): This surgical procedure is often recommended for chronic dacryocystitis or recurrent acute episodes. It involves creating a new drainage pathway between the lacrimal sac and the nasal cavity.
- Balloon Dacryoplasty: A minimally invasive procedure that uses a small balloon to widen the blocked duct.
- Probing and Irrigation: In infants and young children, probing and irrigation of the nasolacrimal duct may be performed to clear the obstruction.
Preventive Measures
- Hygiene Practices: Maintaining good eye hygiene and avoiding rubbing the eyes can help prevent infections.
- Manage Allergies and Sinus Conditions: Proper management of underlying conditions such as allergies and sinusitis can reduce the risk of dacryocystitis.
Frequently Asked Questions
1. What are the symptoms of Dacryocystitis?
Symptoms may include redness and swelling in the tear duct area, discharge from the eye, and excessive tearing.
2. What causes Dacryocystitis?
Causes are often linked to blockage or infection of the nasolacrimal duct, leading to inflammation and infection of the tear sac.
3. How is Dacryocystitis diagnosed?
Diagnosis typically involves clinical evaluation, history of symptoms, and sometimes imaging studies to assess duct blockage.
4. What treatment options are available for Dacryocystitis?
Treatment may include antibiotics, warm compresses, and surgical intervention if necessary to relieve blockage.
5. How does Dacryocystitis relate to tear duct infection?
It is specifically characterized by infection or blockage in the tear duct system, leading to symptoms of inflammation and discharge.
