supraversion
Also called supravergence
Supraversion is the version that elevates both eyes, and the same movement is also called sursumversion. A version is a synchronous, simultaneous movement of the two eyes in the same direction.1
The superior rectus and inferior oblique act together as the elevators of each eye. The pair of elevators in one eye is yoked as a unit to the pair in the fellow eye, so all four elevators take part in supraversion.1
Supraversion differs from supravergence, which is a vertical vergence that moves the two eyes in opposite vertical directions.1 Supravergence is measured as a vertical fusional amplitude with base-down prism.2
