Bilateral cortical blindness: an unusual presentation of bacterial endocarditis.

We report the case of a 37-year-old woman who presented to the emergency department with the initial complaint of complete blindness. The patient was found to have bilateral ruptured occipital mycotic aneurysms as a sequela of bacterial endocarditis. This case is unique in several aspects. Although blindness may be a presenting neurologic symptom, it is exceedingly rare. To our knowledge, bilateral cortical blindness secondary to mycotic aneurysm rupture has not been reported previously.
