Background:
Postoperative bacterial endophthalmitis is caused by the patient's endogenous flora in most cases (80 %). Pasteurella multocida (PM) is a Gram-negative coccobacillus found in the upper respiratory tract of dogs and cats and is very rarely implicated in postoperative endophthalmitis.
History And Signs:
We describe a case of PM endophthalmitis that developed after cataract surgery.
Therapy And Outcome:
Cultures of both the conjunctiva and the aqueous humor were positive for PM. Topical, intravitreous and intravenous antibiotics were administered. Despite treatment, the outcome was unfavourable and complicated by a corneal perforation.
Conclusions:
The prognosis of postoperative PM endophthalmitis remains poor, despite adequate treatment of the infection. A history of recent pet exposure should alert physicians to this possible aetiological factor.
Insights
Postoperative bacterial endophthalmitis from Pasteurella multocida (PM) is rare but serious. This case highlights the poor prognosis and need for physician awareness of pet exposure in endophthalmitis diagnosis.
Area of Science:
- Ophthalmology
- Microbiology
- Infectious Diseases
Background:
- Postoperative endophthalmitis is typically caused by endogenous flora (80%).
- Pasteurella multocida (PM), a Gram-negative coccobacillus from pets, is rarely implicated in endophthalmitis.
Observation:
- A case of endophthalmitis developed post-cataract surgery.
- Conjunctival and aqueous humor cultures confirmed PM infection.
Findings:
- Treatment included topical, intravitreous, and intravenous antibiotics.
- Despite treatment, the outcome was unfavorable, leading to corneal perforation.
Implications:
- Prognosis for PM endophthalmitis remains poor, even with treatment.
- Physicians should consider pet exposure as a potential cause in endophthalmitis cases.
