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.
