A rare cause of canaliculitis, Mycobacterium chelonae, was identified in a patient with persistent symptoms. Surgical intervention resolved the infection, highlighting a unique etiology for this common eye condition.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Canaliculitis is an inflammation of the tear canaliculus, often presenting with discharge and swelling.
  • Actinomyces species are the most common bacterial cause of canaliculitis.

Observation:

  • A 34-year-old immunocompetent woman presented with a 6-week history of right inferior medial canthal swelling and discharge.
  • Conservative medical therapy failed to resolve the patient's symptoms.

Findings:

  • Surgical intervention, including canaliculotomy and dacryolith removal, led to symptom resolution.
  • The causative agent identified was Mycobacterium chelonae, a rare cause of canaliculitis.

Implications:

  • This case expands the known spectrum of pathogens causing canaliculitis.

  • Mycobacterium chelonae should be considered in refractory cases of canaliculitis, especially in immunocompetent individuals.
