Most of the cases reported were due to gunshot wounds and shotgun wounds to the neck and face. When the foreign body is near the great vessel, it must be removed immediately or will cause complications. This study reported a case of delayed metallic foreign body embolus to the ophthalmic artery resulting from an injury to the right neck, which arose from the presence of metallic emboli to the cerebral circulation.展开更多
