As a result of the torsional drift the pulling direction of the recti muscles are altered mimicking oblique overaction in the nonviewing eye.
Imbalance between the tone of superior and inferior obliques and relative overaction of superior oblique in response to premotor inputs naturally predicts increased ocular tilt responses during head tilt causing otolith stimulation.

V-pattern strabismus is more common in both esodeviations and exodeviations the reported range is from 59% to 100% (15) Affected patients typically demonstrate moderate to severe inferior oblique overaction and mild to moderate superior oblique underaction.
Imaging studies will yield valuable information when documentation of previous surgery is unavailable, when orbital repositioning has been performed, or when there is marked apparent oblique dysfunction (such as IO overaction, SR or SO underaction).
