Tonic upgaze in infancy. A report of three cases.
Episodic conjugate tonic upgaze unassociated with seizures or downgaze palsy was noted in three infants during the first months of life. With age, the episodes became shorter and less frequent and were most notable during periods of fatigue or illness. This phenomenon may be analogous to transient tonic downward deviation of the eyes in healthy infants.
