Shewannela putrefaciens endophthalmitis after penetrating keratoplasty
Purpose:
To report a case of Shewannela putrefaciens endophthalmitis after penetrating keratoplasty.
Methods:
Case report. Vitreous of the recipient and the preservative medium of donor cornea were cultured.
Results:
Vitreous of the recipient eye and the donor eye corneal preservative medium both grew S putrefaciens. The patient failed to respond to intravitreal, topical, and systemic amikacin and cefotaxime. Vision was lost rapidly. Evisceration was performed.
Conclusion:
Shewannela putrefaciens should be considered as a potential pathogen contaminating donor cornea. Shewannela putrefaciens endophthalmitis is devastating and responds poorly to medical treatment.
Insights
Shewannela putrefaciens endophthalmitis is a devastating post-keratoplasty infection. This case highlights the poor response to standard treatments and the potential for donor cornea contamination.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Endophthalmitis is a severe intraocular infection.
- Penetrating keratoplasty is a common corneal transplantation procedure.
