Background:
Listeria monocytogenes is a rare cause of endogenous endophthalmitis. In the limited number of reported Listeria endophthalmitis cases, visual acuity outcomes have been very poor.
Findings:
Here, we report a case of Listeria endophthalmitis that was complicated by recurrent inflammation. The patient required treatment with both intravitreal and long-term systemic antibiotics. An anterior chamber washout was necessary for the patient to regain 20/20 visual acuity.
Conclusions:
This case highlights the importance of considering Listeria early in the disease course, as it has low sensitivity to standard empiric antibiotic therapy. It also stresses the importance of addressing damaging inflammation in infectious conditions.
Insights
Listeria endophthalmitis, a rare infection, can lead to poor vision. Prompt diagnosis and aggressive treatment, including antibiotics and inflammation management, are crucial for visual recovery in these challenging cases.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Listeria monocytogenes is an uncommon cause of endogenous endophthalmitis.
- Previous cases of Listeria endophthalmitis report poor visual acuity outcomes.
Purpose of the Study:
- To report a case of Listeria endophthalmitis with recurrent inflammation.
- To highlight treatment strategies and outcomes for this rare condition.
Main Methods:
- A case report detailing the clinical course of Listeria endophthalmitis.
- Treatment involved intravitreal and systemic antibiotics, and anterior chamber washout.
Main Results:
- The patient experienced recurrent inflammation despite initial treatment.
- Successful visual acuity recovery to 20/20 was achieved after anterior chamber washout.
- Listeria species demonstrate low sensitivity to standard empiric antibiotic regimens.
Conclusions:
- Early consideration of Listeria monocytogenes in endophthalmitis is vital due to its resistance to common therapies.
- Aggressive management of inflammation is critical for favorable visual outcomes in infectious endophthalmitis.
