Stenosis of the Tear Duct

Overview

The tear drainage system, also called the lacrimal system, is a complex network of structures responsible for producing, distributing, and draining tears from the eyes. Tears are essential for maintaining eye health, providing lubrication, nutrients, and protection against infections. The nasolacrimal duct is the final pathway in this drainage system, carrying tears from the lacrimal sac into the nasal cavity.

When stenosis (narrowing) or complete obstruction occurs in the tear duct, tears cannot drain properly and begin to accumulate on the eye's surface and overflow onto the cheek. This condition can be congenital (present from birth) or acquired later in life due to various factors including infection, trauma, inflammation, or age-related changes.

Tear duct stenosis affects people of all ages but shows a bimodal distribution, with peaks in newborns (affecting 1-6% of all babies) and in adults over 40 years old, particularly women. The condition can be unilateral (affecting one eye) or bilateral (affecting both eyes), though unilateral cases are more common in acquired forms.

While tear duct stenosis is not life-threatening, it can significantly impact quality of life, causing embarrassment from constant tearing, vision problems from excess tears, and recurrent infections. The good news is that effective treatments are available, ranging from conservative management to surgical procedures, with high success rates for symptom relief.

Symptoms

The symptoms of tear duct stenosis result from impaired tear drainage and can range from mild discomfort to significant functional impairment. Understanding these symptoms helps in early recognition and appropriate treatment.

Primary Symptoms

• Lacrimation - excessive tearing or watery eyes
• White discharge from eye - thick, mucoid, or purulent drainage
• Symptoms of eye - general eye discomfort and irritation
• Abnormal movement of eyelid - eyelid changes due to chronic irritation

Secondary Symptoms

• Cough - from tears draining into throat when partial drainage occurs
• Blurred vision from excess tears on the eye surface
• Crusting around the eyelids, especially upon waking
• Redness and swelling of the eyelids
• Pain or tenderness around the inner corner of the eye
• Mucus or pus discharge that may cause eyelids to stick together

Acute Infection Symptoms

When tear duct obstruction leads to infection (dacryocystitis), additional symptoms may include:

• Sudden onset of severe pain and swelling near the inner corner of the eye
• Red, warm, tender swelling over the lacrimal sac
• Fever and general malaise
• Purulent discharge when pressure is applied to the lacrimal sac
• Spreading redness and swelling around the eye
• Cellulitis of the surrounding eyelid and facial tissues

Chronic Symptoms

• Persistent watery eyes that worsen in cold or windy weather
• Recurrent episodes of eye discharge and crusting
• Chronic irritation and redness of the affected eye
• Social embarrassment from constant tearing
• Difficulty wearing contact lenses
• Skin irritation and maceration around the eye from constant moisture

Age-Specific Symptom Patterns

In Newborns and Infants

• Excessive tearing appearing within the first few weeks of life

Causes

Tear duct stenosis can result from various factors that cause narrowing or complete obstruction of the nasolacrimal drainage system. Understanding these causes helps in prevention and appropriate treatment selection.

Congenital Causes

• Lacrimal sac massage: Gentle pressure and massage to help open blocked ducts
• Artificial tears: To supplement tear production and improve comfort
• Antibiotic drops or ointments: For secondary bacterial infections
• Anti-inflammatory medications: Topical or systemic steroids for inflammation

Observation and Monitoring

• Many congenital obstructions resolve spontaneously by 12 months of age
• Regular follow-up to monitor progression
• Patient education on symptom management

Minimally Invasive Procedures

Probing and Irrigation

• Simple probing: Passage of thin probe to open obstruction
• Balloon dacryoplasty: Balloon inflation to dilate narrowed areas
• Silicone intubation: Temporary stent placement to maintain patency
• Usually performed under local anesthesia
• High success rate for partial obstructions

Endoscopic Procedures

• Balloon catheter dilation: Minimally invasive opening of obstructions
• Laser dacryoplasty: Use of laser to open blocked areas
• Performed through nasal approach
• Faster recovery compared to external surgery

Surgical Treatment

Gold standard surgical treatment for complete obstructions:

• Creation of new pathway between lacrimal sac and nasal cavity
• Removal of bone between sac and nose
• High success rate (90-95%)
• Performed under general or local anesthesia
• Small external incision near the inner corner of eye

Endoscopic DCR

• Same principle as external DCR but performed through nose
• No external scar
• Slightly lower success rate than external approach
• Faster recovery time
• Can be combined with sinus surgery if needed

Conjunctivodacryocystorhinostomy (CDCR)

• Used when there's extensive canalicular damage
• Bypass tube connects conjunctival sac to nasal cavity
• More complex procedure with lower success rates
• Reserved for severe cases

Age-Specific Treatment Approaches

Infants and Children

• Conservative management: First-line approach with massage and observation
• Probing: If symptoms persist beyond 12 months
• Balloon dacryoplasty: For failed probing
• Silicone intubation: For complex or recurrent obstructions
• DCR rarely needed in children

Adults

• Conservative treatment trial for 4-6 weeks
• Early consideration of surgical intervention
• DCR is often the definitive treatment
• Choice between external and endoscopic approach

Treatment of Complications

Acute Dacryocystitis

• Systemic antibiotics
• Warm compresses
• Pain management
• Surgical drainage if abscess forms
• Definitive surgery after acute infection resolves

Chronic Dacryocystitis

• Long-term antibiotic therapy
