Abstract

Lancefield group G β-hemolytic Streptococcus dysgalactiae subspecies equisimilis (SDSE) has become a leading causative pathogen of invasive streptococcal infection. In this report, we describe a case of disseminated SDSE infection complicated by endogenous endophthalmitis, resulting in panophthalmitis and blindness. A 65-year-old man who underwent mitral valve replacement surgery two months previously was hospitalized due to high fever and right visual loss. A systemic investigation revealed endophthalmitis complicated by mediastinal abscess, prosthetic infective endocarditis, cerebral emboli and hemorrhage, and multiple arthritis. The patient underwent various surgeries, including vitrectomy, mediastinal lavage, mitral valve replacements, joint lavages, as well as an intensive antibiotic treatment. His general condition gradually improved, but the ocular infection developed to panophthalmitis, which ultimately required ophthalmectomy. A literature review regarding Group G-associated endogenous endophthalmitis suggested that the disease occurs in elderly people, is frequently complicated with endocarditis, and yields poor visual prognosis regardless of appropriate antibiotic treatment and surgical therapies. In this aging society, invasive infections with SDSE should be much more recognized among medical practitioners in order to improve patient prognosis.
