# Dacryoliths

Dacryoliths are small, stone-like deposits that form inside the tear drainage passages. They can partially or completely block the system, leading to watery eyes or tear sac infections.

## What dacryoliths are made of

These concretions consist of mucus, skin cells, and mineral salts. They gradually harden and may move within the ducts or tear sac.

- Many are found incidentally during surgery for watery eyes.
- They may be single or multiple and vary in size.
- Long-standing inflammation seems to encourage their formation.
- Symptoms often mimic other causes of epiphora.
- Imaging or probing can sometimes reveal their presence.

## Managing dacryolith-related problems

Treatment aims to clear the obstruction and prevent recurrent infections. Approaches are similar to those used for other tear drainage blockages.

- Antibiotics treat active infections of the tear sac or surrounding tissues.
- Surgical exploration allows removal of dacryoliths under direct vision.
- Creating a new drainage route into the nose may be recommended.
- Most people notice rapid improvement in watering after successful surgery.
- Regular follow-up ensures the passage remains open and comfortable.
