Purpose:
To describe a case of primary meningococcal conjunctivitis mimicking epidemic keratoconjunctivitis.
Methods:
Review of a case history and current literature.
Results:
A 28-year-old man presented with 5 days of a bilateral follicular conjunctivitis and subepithelial corneal infiltrates. Initial diagnosis of adenoviral conjunctivitis was made. Initial Gram stain of conjunctival exudates was negative. Cultures grew Neisseria meningitidis. Systemic antibiotics were instituted with adjunctive topical therapy. The conjunctivitis resolved with no evidence of systemic invasion.
Conclusions:
The clinical picture of Neisseria meningitidis conjunctivitis can overlap with other infectious organisms including adenovirus. Early diagnosis and systemic antibiotic therapy are critical to prevent bacteremic spread of infection.
Insights
Primary meningococcal conjunctivitis can mimic viral infections like epidemic keratoconjunctivitis. Prompt diagnosis and systemic antibiotics are crucial to prevent serious complications.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Primary meningococcal conjunctivitis is rare but can present with symptoms similar to epidemic keratoconjunctivitis.
- Distinguishing between bacterial and viral causes of conjunctivitis is essential for appropriate treatment.
Observation:
- A 28-year-old male presented with bilateral follicular conjunctivitis and subepithelial corneal infiltrates, initially suspected as adenoviral.
- Initial diagnostic tests, including Gram stain, were negative, delaying the identification of Neisseria meningitidis.
Findings:
- Conjunctival cultures confirmed Neisseria meningitidis infection.
- The patient received systemic antibiotics and topical therapy, leading to resolution of conjunctivitis without systemic spread.
Implications:
- This case highlights the importance of considering Neisseria meningitidis in the differential diagnosis of severe conjunctivitis, even with initial negative results.
- Early and accurate diagnosis with appropriate systemic antibiotic treatment is critical to prevent potential bacteremic complications associated with meningococcal infections.
