Acutely, utricular damagecan also cause hyperdevation. It would seem to us that saccular damage might also cause hyperdeviation, but this has not been reported in the literature to our knowledge. Alternating skew deviation, in which the hypertropic eye occurs on the side of horizontal gaze direction, is associated with lesions of the cervicomedullary junction or cerebellar pathways. Ocular tilt reaction
In normal humans, static lateral head tilt causes sustained low-amplitude counter-roll of the eyes and a small vertical misalignment, so that the lower eye is a little higher than the upper eye. This has the effect of modestly realigning the axis between the eyes with horizontal. Pathologically, the ocular tilt reaction consists of a triad of skew deviation, ocular torsion and head tilt.
