Abstract:
Endogenous endophthalmitis of bacterial or fungal origin is a rare condition, accounting for 5 to 10% of all endophthalmitis cases. Different risk factors have been identified and ocular involvement is usually due to one or multiple systemic infectious abscesses with variable virulence. Clinical symptoms may initially mimic a panuveitis and will delay diagnostic confirmation. Ancillary tests will determine the infectious source and isolate the causative agent. Specific therapy is based on systemic and intravitreal antibiotics or antifungals associated with a pars plana vitrectomy in severe cases. Despite an aggressive therapeutic strategy, visual prognosis remains guarded. Education of ophthalmologists and infectious disease specialists may decrease diagnostic delay so that specific antimicrobial agents can be initiated promptly and thus avoid a permanent blindness.
Insights
Endogenous endophthalmitis, a rare eye infection from systemic sources, requires prompt diagnosis and treatment. Early intervention with antimicrobials and surgery improves visual outcomes in this challenging condition.
Area of Science:
- Ophthalmology
- Infectious Diseases
Context:
- Endogenous endophthalmitis is a rare but severe intraocular infection.
- It originates from a distant systemic infection, often bacterial or fungal.
- Accounts for 5-10% of all endophthalmitis cases.
Purpose:
- To review the etiology, diagnosis, and management of endogenous endophthalmitis.
- To highlight the importance of early recognition and treatment for visual preservation.
Summary:
- Ocular involvement stems from systemic abscesses with varying virulence.
- Clinical presentation can mimic panuveitis, delaying diagnosis.
- Ancillary tests identify the infectious source and causative agent.
- Treatment involves systemic/intravitreal antimicrobials and potentially pars plana vitrectomy.
- Visual prognosis remains guarded despite aggressive therapy.
Impact:
- Prompt diagnosis and targeted antimicrobial therapy are crucial.
- Education for ophthalmologists and infectious disease specialists can reduce diagnostic delays.
- Effective management aims to prevent permanent vision loss.
