Dacryolithiasis refers to the presence of stones (dacryoliths) within the lacrimal drainage system, most often in the lacrimal sac. These concretions can obstruct tear flow and predispose to infection.
Causes and Features
Dacryoliths are usually composed of mucus, debris, and mineral deposits. They may form in association with chronic inflammation or stagnation of tears.
- Symptoms include watering, discharge, and recurrent dacryocystitis
- Often discovered during imaging or surgery for tear duct obstruction
- Can occur in adults of any age
Diagnosis and Management
Diagnosis is based on history, examination, and sometimes imaging such as dacryocystography or nasal endoscopy. Treatment involves removal of the stones and addressing any underlying obstruction, commonly through procedures such as dacryocystorhinostomy.
