Summary

Chronic blepharoconjunctivitis in a 70-year-old woman was successfully treated with cefazolin. The cause was identified as Capnocytophaga ochracea, a bacterium often overlooked in ocular infections.

Area of Science:

  • Ophthalmology
  • Microbiology
  • Infectious Diseases

Background:

  • Chronic blepharoconjunctivitis can be challenging to treat.
  • Identifying the causative agent is crucial for effective therapy.

Observation:

  • A 70-year-old woman presented with a 10-month history of recalcitrant blepharoconjunctivitis.
  • Microscopic examination revealed slender, fusiform bacilli on conjunctival smears.
  • The patient had no known risk factors for severe ocular infections.

Findings:

  • Culture of conjunctival scrapings identified the fastidious bacterium Capnocytophaga ochracea.
  • Capnocytophaga ochracea was also isolated from the patient's gingival cultures.
  • Treatment with fortified cefazolin eye drops resolved the blepharoconjunctivitis.

Implications:

  • Capnocytophaga ochracea should be considered in the differential diagnosis of chronic or unresponsive blepharoconjunctivitis.
  • Microbiological techniques, including Gram staining and culture, are essential for diagnosing infections caused by fastidious organisms.
  • Prompt and accurate diagnosis can lead to effective treatment and improved patient outcomes.
