Endogenous Endophthalmitis in Patients with MRSA Septicemia: A Case Series and Review of Literature.

PURPOSE: To report the presentation, predisposing factors, clinical features and outcome in 6 eyes of 3 patients with endogenous endophthalmitis secondary to methicillin resistant staphylococcus aureus (MRSA) septicaemia.

METHODS

Retrospective review of case records of 3 patients who were treated for endogenous endophthalmitis secondary to MRSA septicaemia in a tertiary referral institution.

RESULTS

All three patients had systemic predisposition to endogenous endophthalmitis (diabetes, urosepsis). Two patients presented within 1 week of onset of visual symptoms and the third after 3 months. Blood culture was positive for MRSA in all patients. Visual and anatomical improvement was noted in two patients who presented early. The third patient's visual outcome despite early treatment with intravitreal antibiotics and vitrectomy was not satisfactory.

CONCLUSION

Endogenous endophthalmitis by MRSA is a rare but serious condition. Early and specific therapy based on reliable detection of the underlying microorganism is needed for good anatomical and functional outcome.
