9A11.1/H04.3 Canaliculitis



Canaliculitis is an inflammation of the tear ducts, or canals, which connect the eyes to the nose. It is usually caused by a bacterial infection, such as Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. It can also be caused by a viral infection, such as herpes simplex virus or adenovirus.


Canaliculitis is usually diagnosed through a physical examination and a detailed history of symptoms. The doctor may also order laboratory tests, such as a culture of the discharge from the tear ducts, to confirm the diagnosis.

Differential diagnosis

Other conditions that can cause similar symptoms to canaliculitis include conjunctivitis, blepharitis, and dacryocystitis.


Treatment for canaliculitis typically involves antibiotics, either oral or topical, to treat the infection. Your doctor may also prescribe eye drops or ointments to reduce inflammation and irritation.


The prognosis for canaliculitis is usually good. Most cases can be cured with proper treatment. However, if the infection is not treated or is left untreated, it can lead to serious complications, such as infection of the tear ducts or vision loss.
