REPORT OF A CASE  Ten days after having had an upper respiratory tract infection, a 15-year-old boy became dizzy and noticed blurred and double vision. His symptoms remained unchanged until three days later, when nausea, vomiting, and difficulty in walking developed. Examination found complete upward gaze paralysis and horizontal nystagmus.

The pupils were 4 mm in diameter and reacted normally to light. There was slight symmetric limitation of gaze to either side
