Blindness following minor head trauma in children: a report of two cases with a review of the literature.
The spectrum of closed head injury ranging from asymptomatic to lethal is well described in the literature. In a small number of cases, dramatic neurologic symptoms normally associated with cerebrovascular accident or vascular headache may arise following apparently insignificant head trauma. We report two cases of young males who developed transient blindness accompanied by significant neurologic abnormality following trivial head injuries. These phenomena are previously well documented, and it is believed that in certain individuals, minor head trauma can induce a type of migraine equivalent known as "footballer's migraine" or "posttraumatic cortical blindness." Current knowledge of these two conditions is reviewed.
