Transient blindness following minor head injuries.

Transient bliandness following minor head injury is a rare, although well known, and totally reversible entity. As the condition may have legal implications, a 5-year follow-up study was carried out on 4 young patients. Repeated ophthalmological, neurological and psychiatric examination both early nd late after injury did not reveal any organic or psychiatric diseases which might predispose to this disorder. The case reports, including one recurrent case, a follow-up study and a discussion of the aetiology are presented.
