Infective Endocarditis Presenting as Endogenous Endophthalmitis Secondary to Streptococcus agalactiae in a Healthy Adult: Case Reports and Literature Review

Endogenous endophthalmitis secondary to group B Streptococcus (GBS) is extremely rare, particularly in healthy adults. However, the visual prognosis is poor. We report the first South Korean case of GBS infective endocarditis presenting as endogenous endophthalmitis and skin and soft tissue infection. Cultures of blood, vitreous humor, and pus from skin aspirates yielded a penicillin-susceptible serotype V strain of Streptococcus agalactiae. After 6 weeks, the patient completely recovered from GBS infective endocarditis. However, despite early antibiotic treatment and early surgical intervention, the patient's right eye developed phthisis bulbi and was a candidate for evisceration.
