Mycobacterium gordonae caused an indolent corneal ulcer in a 20-year-old man, a rare occurrence. This case highlights nontuberculous mycobacterial keratitis without typical predisposing factors like trauma.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Nontuberculous mycobacterial (NTM) keratitis is an uncommon but serious ocular infection.
  • Previous ocular trauma is a frequent predisposing factor for NTM keratitis.
  • Mycobacterium gordonae is a rarely identified cause of human mycobacterial keratitis.

Observation:

  • A 20-year-old male presented with a persistent, indolent corneal ulcer.
  • The patient had no history of ocular trauma or other known predisposing factors for infection.
  • Tissue and cultures were obtained during a penetrating keratoplasty procedure.

Findings:

  • Cultures and tissue analysis definitively identified Mycobacterium gordonae as the causative agent of the keratitis.
  • This represents the third reported case of M. gordonae keratitis in the literature.

  • The indolent nature of the ulcer and lack of typical risk factors distinguish this case.

    • Implications:

    • This case expands the understanding of M. gordonae as a potential pathogen in corneal infections.
    • It underscores the importance of considering atypical mycobacteria in the differential diagnosis of keratitis, even in the absence of trauma.
    • Further research may be needed to elucidate the pathogenesis of M. gordonae keratitis in immunocompetent individuals without predisposing factors.
