Endogenous endophthalmitis secondary to septic arthritis caused by group A Streptococcus infection: A case report and literature review.

Streptococcus pyogenes is a rare pathogen that causes endogenous endophthalmitis (EE). A healthy 58-year-old woman was diagnosed with EE secondary to septic arthritis caused by S. pyogenes. She underwent enucleation after hospitalization for 14 days with appropriate antibiotic cover. A literature search for outcomes of this condition revealed reports on only 10 eyes among 8 cases identified: 8 eyes (80%) developed poor visual outcome and 5 eyes (50%) underwent enucleation. There were no cases with immunocompromise. Our case report and literature review suggest the importance of awareness of the occurrence of S. pyogenes infection in immunocompetent hosts, and thus early diagnosis and aggressive treatment may be required to improve visual outcome.
