Name of the Condition

• Dacryolith of right lacrimal passage
• Also known as: Tear duct stone, Lacrimal duct stone.

Summary

• Dacryolith refers to a stone or concretion that forms within the lacrimal passage, specifically the tear duct. This condition often leads to blockage, causing discomfort and potential tearing of the eye due to impaired drainage.

Causes

• The exact causes of dacryolith formation are not entirely understood but may involve chronic inflammation, infection, or debris buildup within the tear ducts.

Risk Factors

• Age: More common in older adults.
• History of chronic conjunctivitis or other eye infections.
• Narrow or anatomically altered lacrimal passages.

Symptoms

• Excessive tearing or epiphora.
• Pain or discomfort near the inner corner of the eye.
• Possible swelling and redness around the tear duct area.

Diagnosis

• Physical examination with attention to eye and surrounding areas.
• Imaging techniques: dacryocystography or ultrasound to visualize the blockage.

Treatment Options

• Conservative management: Warm compresses and massage to promote drainage.
• Invasive procedures: Dacryocystectomy or dacryocystorhinostomy to remove the stone or establish a new drainage pathway.
• Medications: Antibiotics if an infection is present.

Prognosis and Follow-Up

• Generally good with appropriate treatment.
• Regular follow-up is necessary to monitor for recurring blockage or infection.

Complications

• Recurrent infections leading to chronic dacryocystitis.
• Permanent damage to the lacrimal system if left untreated.

Lifestyle & Prevention

• Maintaining eye hygiene to reduce infection risk.
• Avoiding eye irritants and managing allergies can prevent obstruction.
• Regular eye examinations, especially for those with chronic eye issues.

When to Seek Professional Help

• Persistent tearing or discharge from the eye.
• Significant pain or swelling around the eye.
• Any change in vision or severe discomfort.

Tips for Medical Coders

• Ensure specificity by noting the side (right lacrimal passage) for accurate coding with H04.511.
• Distinguish between dacryolith and other lacrimal conditions to avoid miscoding.
