BB embolus causing monocular blindness in a 9-year-old boy.
PURPOSE: To report a case of monocular blindness resulting from intravascular bullet migration. DESIGN: 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. CONCLUSION: BB gun injuries may result in devastating ophthalmologic as well as systemic consequences due to bullet embolization.
