BB embolus causing monocular blindness in a 9-year-old boy.
OBJECTIVE
To report a case of monocular blindness resulting from intravascular bullet migration.


METHODS
Observational case report.


METHODS
A 9-year-old boy presented to the emergency room with a penetrating BB gun injury to the chest.


RESULTS
Carotid angiography localized the bullet to the right internal carotid artery. He subsequently suffered blindness in the right eye, a right pupil-involving third nerve palsy, left hemiparesis, and a probable left homonymous hemianopia.


CONCLUSIONS
BB gun injuries may result in devastating ophthalmologic as well as systemic consequences due to bullet embolization.
