Rural penetrating trauma causes endophthalmitis (eye infection) more often than non-rural injuries. Bacillus species are common culprits, suggesting specific antibiotic treatments for rural cases.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Trauma Surgery

Background:

  • Current empiric antibiotic regimens for posttraumatic endophthalmitis are based on urban data.
  • Rural penetrating trauma often involves organic matter contamination, potentially leading to different causative organisms.
  • Existing treatment guidelines may not be optimal for endophthalmitis in rural settings.

Purpose of the Study:

  • To investigate the incidence of endophthalmitis following rural penetrating trauma.
  • To identify the specific microorganisms responsible for rural endophthalmitis.
  • To inform revised empiric antibiotic therapy recommendations for rural endophthalmitis.

Main Methods:

  • A 10-year retrospective analysis of patients with penetrating trauma.

  • Comparison of endophthalmitis incidence between rural and non-rural injury groups.
  • Microbiological analysis of causative organisms in rural endophthalmitis cases.

    • Main Results:

    • Endophthalmitis developed in 30% of rural trauma patients versus 11% of non-rural trauma patients.
    • Bacillus species were the most common isolates (46%) in rural endophthalmitis.
    • Mixed infections occurred in 42% of rural cases, with Bacillus species frequently involved.

    Conclusions:

    • Rural penetrating trauma is associated with a higher incidence of endophthalmitis.
    • Bacillus species and polymicrobial infections are characteristic of rural endophthalmitis.
    • Intravitreal gentamicin with vancomycin or clindamycin is suggested for empiric therapy.
