Canaliculitis is infection of the lacrimal canaliculus, also called the lacrimal duct (see Eyelid and Tearing Disorders: Viewing the Lacrimal Structures ).
Canaliculitis may cause tearing, discharge, red eye, and mild tenderness. Redness and tenderness are most prominent at the side of the eye near the nose. The symptoms can resemble those of dacryocystitis.
An ophthalmologist (a medical doctor who specializes in diagnosing and treating eye disorders and doing eye surgery) can often irrigate the infected duct with an antibiotic solution. People should then apply warm compresses and use antibiotic eye drops. Occasionally, the infection requires surgical treatment.
