    This study reports a rare case of Pasteurella multocida endophthalmitis following a cat bite, leading to retinal detachment. Prompt treatment involving antimicrobial chemotherapy and vitrectomy successfully managed the infection and vision was partially restored.

    Area of Science:

    • Ophthalmology
    • Infectious Diseases
    • Veterinary Medicine

    Background:

    • Endophthalmitis is a severe intraocular inflammation, often caused by bacterial or fungal infections.
    • Ocular trauma, particularly penetrating injuries, increases the risk of endophthalmitis.
    • Animal bites are a potential, though rarely reported, source of ocular infections.

    Observation:

    • A patient presented with endophthalmitis and retinal detachment attributed to a cat bite.
    • The causative organism identified was Pasteurella multocida, directly inoculated from a globe-perforating wound.
    • The clinical presentation highlights a novel association between animal bites and endophthalmitis.

    Findings:

    • Intensive systemic antimicrobial chemotherapy and pars plana vitrectomy were employed for treatment.

  • Repeated vitrectomies were necessary to resolve the intraocular inflammation.
  • The subsequent retinal detachment was surgically repaired using fluid-gas exchange and scleral buckling.

    • Implications:

    • This case expands the known spectrum of ocular infections secondary to animal bites.
    • Highlights the importance of considering zoonotic infections in cases of severe ocular trauma.
    • Emphasizes the critical role of prompt and aggressive management in preserving vision in complex endophthalmitis cases.
