Citrobacter endophthalmitis, an eye infection, often leads to poor vision despite antibiotic treatment. Early detection and management are crucial for better visual outcomes and to avoid evisceration.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Endophthalmitis is a serious intraocular infection that can lead to vision loss.
- Citrobacter species are Gram-negative bacteria that can cause opportunistic infections.
Observation:
- This study reviewed 6 cases of endophthalmitis caused by Citrobacter freundii or Citrobacter koseri.
- Infections occurred after various ocular surgeries (cataract, trabeculectomy, keratoplasty), trauma, or from endogenous sources.
- Three patients required evisceration, and five had no light perception vision.
Findings:
- Citrobacter endophthalmitis demonstrated poor visual outcomes, with 5 out of 6 patients experiencing no light perception.
- One case of traumatic Citrobacter koseri endophthalmitis achieved a final visual acuity of 20/30.
- Antibiotic sensitivity patterns varied, but outcomes remained poor despite appropriate treatment.
Implications:
- Early diagnosis and prompt management of Citrobacter endophthalmitis are critical for improving visual prognosis.
- Aggressive treatment may help prevent severe vision loss and the need for evisceration.
- Understanding the clinical spectrum and outcomes is vital for ophthalmologists managing these challenging infections.
