Dacryolithiasis refers to tiny stones or concretions forming within the tear drainage system. These dacryoliths can block the ducts and cause persistent watering or infections.
How dacryolithiasis develops
Mucus, debris, and minerals build up within the tear sac or ducts. Over time they harden into small, chalky lumps that obstruct normal tear flow.
- Symptoms include watery eyes, recurrent sticky discharge, or mild discomfort.
- Episodes of painful swelling over the inner corner suggest infection.
- The condition is more common in adults and may affect one or both sides.
- Examination and imaging help locate the blockage.
- Dacryoliths are often discovered during drainage surgery.
Treatment options
Removing the stones and restoring drainage usually settles symptoms. Treatment choice depends on the site and extent of blockage.
- Acute infections are treated first with antibiotics and warm compresses.
- Irrigation or endoscopic procedures can flush out small dacryoliths.
- Dacryocystorhinostomy surgery creates a new drainage channel into the nose.
- Most patients enjoy long-term relief once the system is clear.
- Prompt review reduces the risk of repeated painful infections.
