# Canaliculitis

Canaliculitis is a chronic infection of the tear drainage canaliculi near the inner corner of the eyelids. It often causes persistent discharge and redness.

## Signs and causes

The condition is frequently underdiagnosed because it can mimic conjunctivitis.

- Localised tenderness and pouting of the punctum
- Chronic mucous or gritty discharge that may contain "sulphur granules"
- Often caused by Actinomyces species or other bacteria and fungi
- Expression of concretions when the canaliculus is pressed

## Treatment

Successful management usually requires both surgery and medication.

- Canaliculotomy with curettage to remove infected concretions
- Topical and sometimes systemic antibiotics guided by culture
- Warm compresses and lid hygiene to support healing
- Follow-up to ensure symptoms resolve and drainage function returns
