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.
The cause of most cases is unknown, but a blocked tear duct may increase the risk of canaliculitis. Cosmetics may play a role in blocking the tear duct and therefore encouraging growth of bacteria. Actinomyces israelii, Staphylococcus and Streptococcus have been isolated. It can usually be diagnosed by looking at the eye, and if required can be confirmed by dacryocystography and ultrasound biomicroscopy.
It accounts for around 2% of tear duct diseases. The upper eye lid is less affected than the lower lid, and females are at greater risk. The condition may be easily missed or misdiagnosed, and is probably not as rare as appears.
Signs and symptoms
Diagnosis is by its appearance.
Canaliculitis may appear similar to longterm conjunctivitis, chalazion, hordeolum internum, and longterm dacryocystitis.
