Summary
Acinetobacter johnsonii rarely causes endophthalmitis, but this case highlights its potential after eye trauma. Prompt treatment with antibiotics and surgery improved vision significantly.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Endophthalmitis, an inflammation of the eye's interior, can lead to vision loss.
- Post-traumatic endophthalmitis is a serious complication following ocular injury.
- Acinetobacter species are increasingly recognized as opportunistic pathogens.
Observation:
- A 40-year-old male presented with endophthalmitis and vision loss after a steel fragment caused an open globe injury.
- Intraocular foreign body was identified, necessitating surgical intervention.
- Acinetobacter johnsonii was successfully isolated from vitreous cultures.
Findings:
- The patient underwent pars plana vitrectomy, intravitreal antibiotics, and foreign body extraction.
- Treatment involved a combination of vancomycin, levofloxacin, and ceftazidime.
- Post-operative visual acuity improved to 20/63 at one month and remained stable at one year.
Implications:
- Acinetobacter johnsonii should be considered a potential pathogen in post-traumatic endophthalmitis.
- Early diagnosis and aggressive management are crucial for favorable visual outcomes.
- This case underscores the importance of considering rare bacterial species in severe ocular infections.
