Reports of invasive Group B Streptococcus infection in adults with und
erlying medical conditions have been increasing. Ocular infection with
this organism is unusual. Metastatic endophthalmitis in adults caused
by this organism has been reported rarely and has only been associate
d with endocarditis. We encountered two cases of Group B streptococcal
metastatic endophthalmitis in adults who did not have endocarditis. T
hese cases reflect the increasing incidence of invasive Group B Strept
ococcus infection with its varying manifestations. Additionally, they
emphasize the importance of considering this pathogen as a cause of me
tastatic endophthalmitis in adults with predisposing illnesses.
