Abstract
Ocular counter rolling (OCR) is the approximately conjugate rotational movement of the eyes about their visual axes, rotating opposite to the direction of head tilt. OCR may be induced by either angular acceleration acting on the semicircular canals, or by linear acceleration influencing otolith receptors. In the latter instance, the utricles are the main receptors. However, it has been suggested that an extralabyrinthine stimulus i.e., somatosensory input, can evoke OCR. We recorded OCR in six young, healthy volunteers and used eye analysis. We also recorded OCR when the subject sat down on a hard chair with and without a cushion in order to know if there was any effect of somatosensory input to the OCR. We used the Mann-Whitney U-test for the statistical analysis and P<0.05 was considered significant. There was no significant difference between the two groups. We considered there was not enough stimulation to the somatosensory input to affect the otolith-ocular reflex.
