Reye syndrome is a childhood encephalopathy associated with fatty metamorphosis of the viscera of unknown etiology. The eye findings include dilated pupils that react sluggishly to light or not at all, cortical blindness, and papilledema. Treatment is supportive and 20% to 50% of patients recover completely in three to seven days.
