The Ocular tilt reaction (OTR), comprises skew deviation, head tilt and involving structures of the inner ear responsible for maintenance of balance of the body i.e. the semi-circular canals (SCC), utricle and saccule. Normally, a body tilt (along with the initial head tilt) to the right causes a shift of the subjective visual vertical (SVV) to the left resulting in reflex, compensatory orientation of the head to left to realign the SVV to the true vertical.
