[Bacterial endopathalmitis caused by B streptococcus endocarditis].

Abstract

BACKGROUND: Bacterial endophthalmitis is often caused by a shift in the primary focus of infection in the patient's body. It is a high risk disease that can cause the loss of sight. Bacterial endophthalmitis with infectious endocarditis is very rare in Japan. CASE: A fifty-three-year-old woman visited our clinic complaining of pain, fever, and visual impairment in her left eye. OBSERVATIONS: The patient's left eye was blind, and showed hapopyon in the anterior chamber. She was admitted to our hospital with a diagnosis of endophthalmitis. Medical treatment with antibiotics was carried out, but the inflammation in her left eye increased. Her left eye was enucleated, and group B Streptococcus was found in the vitreous specimen. Echocardiography demonstrated vegetation of the posterior mitral valve. The diagnosis was made of endophthalmitis due to infectious endocarditis. CONCLUSION: We report an endophthalmitis patient with infectious endocarditis caused by group B streptococcus, based on histopathological findings. This is the first such case reported in Japan.
