Early diagnosis and intensive topical clindamycin are crucial for treating Capnocytophaga keratitis. This bacterial eye infection requires prompt identification and appropriate antimicrobial therapy to preserve vision and prevent severe complications like enucleation.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Capnocytophaga is a gram-negative rod that can cause severe keratitis.
  • Keratitis requires prompt diagnosis and effective treatment to prevent vision loss.

Purpose of the Study:

  • To review the clinical course, treatment, and visual outcomes of keratitis caused by Capnocytophaga.
  • To identify key factors influencing visual outcomes in Capnocytophaga keratitis.

Main Methods:

  • Retrospective, noncomparative case series of 10 patients with culture-proven Capnocytophaga keratitis.
  • Standard diagnostic microbiologic evaluation and topical antimicrobial therapy were administered.
  • Surgical interventions such as penetrating keratoplasty or enucleation were performed in select cases.

Main Results:

  • All patients had predisposing factors for keratitis.
  • Initial treatments varied, but intensive topical clindamycin was used in four patients after identification.
  • Five eyes achieved 20/80 or better visual acuity, with four of these treated with clindamycin; five eyes required enucleation due to persistent infection or complications.

Conclusions:

  • Early microbiologic identification and intensive topical clindamycin therapy are vital for favorable visual outcomes in Capnocytophaga keratitis.
  • Capnocytophaga should be considered in the differential diagnosis of bacterial keratitis, especially in cases with predisposing factors or treatment resistance.
