excyclovergence

Rotary movements about their respective anteroposterior axes of one eye relative to the other. If the upper pole of the cornea of one eye moves away from that of the other eye, it is called excyclovergence. If, however, the upper pole of the cornea of one eye moves towards that of the other eye, it is called incyclovergence.
