# Dacryolithiasis

[Dacryolithiasis refers to tiny stones or concretions](https://bluefinvision.com/blog/what-is-dacryolithiasis/) 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.
