Summary
Nutrient variant streptococci (NVS) can cause late-onset endophthalmitis after filtering surgery. Prompt diagnosis and treatment with antibiotics improved vision in this unique case.
Area of Science:
- Ophthalmology
- Microbiology
Background:
- Late-onset endophthalmitis following filtering bleb surgery is typically caused by streptococci.
- Identifying the specific causative agent is crucial for effective treatment.
Observation:
- A case of endophthalmitis was observed following filtering bleb surgery.
- The causative agent was identified as nutrient variant streptococci (NVS), likely originating from the oral cavity.
Findings:
- This is the first reported case of endophthalmitis caused by nutrient variant streptococci (NVS).
- The patient's vision improved significantly from light perception to 20/80 with intravitreal and systemic antibiotic therapy.
Implications:
- Nutrient variant streptococci (NVS) should be considered a potential pathogen in late-onset endophthalmitis.
- Laboratories must be alerted to culture specifically for this fastidious bacterium to ensure accurate diagnosis.
