Canaliculitis is an infection of the lacrimal canaliculus of the eye, typically presenting with excess tears, redness, pain and swelling of part of the eyelid, followed by a swelling of the inner corner of the eye near the nose.[1]

The cause of most cases is unknown, but a blocked tear duct may increase the risk of canaliculitis.[1] Cosmetics may play a role in blocking the tear duct and therefore encouraging growth of bacteria.[1] Actinomyces israelii, Staphylococcus and Streptococcus have been isolated.[2] It can usually be diagnosed by looking at the eye, and if required can be confirmed by dacryocystography and ultrasound biomicroscopy.[1]

It accounts for around 2% of tear duct diseases.[1] The upper eye lid is less affected than the lower lid, and females are at greater risk.[1] The condition may be easily missed or misdiagnosed, and is probably not as rare as appears.[1]

Signs and symptoms


Diagnosis is by its appearance.[1]

Differential diagnosis

Canaliculitis may appear similar to longterm conjunctivitis, chalazion, hordeolum internum, and longterm dacryocystitis.[1]
