From the Research

Yes, infective endocarditis can cause endophthalmitis through hematogenous spread of bacteria or fungi from infected heart valves to the eye, as reported in a case study published in 2021 1. This occurs when microorganisms from the bloodstream cross the blood-ocular barrier and establish infection within the eye.

Key Points

  • Endophthalmitis is a rare but serious complication of infective endocarditis, typically presenting with decreased vision, eye pain, redness, and photophobia.
  • The most common causative organisms include Staphylococcus aureus, Streptococcus species, and Candida.
  • Management requires prompt administration of systemic antibiotics or antifungals that match the causative organism of the endocarditis, often with the same regimen used to treat the primary cardiac infection.
  • In severe cases, intravitreal antibiotics may be necessary, administered by an ophthalmologist.
  • The prognosis depends on rapid diagnosis and treatment, as delayed therapy can result in permanent vision loss, as highlighted in a study published in 2020 2.

Clinical Considerations

  • Patients with endocarditis who develop any visual symptoms should undergo immediate ophthalmologic evaluation to assess for this complication.
  • A case study published in 2012 3 reported a patient with Streptococcus dysgalactiae endocarditis presenting as acute endophthalmitis, emphasizing the importance of prompt diagnosis and treatment.
  • Another study published in 2009 4 highlighted a case of endogenous endophthalmitis due to levofloxacin-resistant Streptococcus mitis presenting as infective endocarditis, underscoring the need for effective antibiotic therapy.

Recommendations

  • Prompt administration of systemic antibiotics or antifungals is crucial in managing endophthalmitis caused by infective endocarditis, as reported in a study published in 2021 1.
  • Immediate ophthalmologic evaluation is necessary for patients with endocarditis who develop visual symptoms.
  • Intravitreal antibiotics may be necessary in severe cases, as highlighted in a study published in 2012 3.
