Polymicrobial endogenous endophthalmitis.

Abstract

We report a case of polymicrobial endogenous endophthalmitis caused by group G streptococcus and Staphylococcus capitis. Standard ophthalmologic examinations. A 72-year-old woman presented with signs of uveitis. Treatment with broad-spectrum antibiotics was prescribed, and vitrectomy with intravitreal antibiotic administration was then performed. Blood cultures were positive for group G streptococcus and coagulase-negative staphylococcus. Cultures of vitreous aspirate yielded group G streptococcus and S. capitis. Uveitis was resolved with antibiotic treatment and vitrectomy, with best-corrected visual acuity of 20/20 at 6 months. Endogenous endophthalmitis can be caused by two intravitreal organisms (e.g., group G streptococcus and S. capitis). Early treatment with broad-spectrum antibiotics and vitrectomy with intravitreal injections of antibiotic might be considered in similar cases.
