Previous studies have shown that in patients with unilateral vestibular deafferentation (UVD) there is a close relationship between the change in ocular torsional position consequent on the UVD, and the visually perceived orientation of short dim lines in an otherwise darkened room (1). However that result may have been confounded because the UVD may have affected both ocular torsion and sensory information about head position re gravity which must be used in making the visual perceptual judgement. Therefore we have sought a means of testing the relationship between ocular torsional position and the visual perception of orientation which was not confounded by the possible effect of changes in perceived head position.
先前的研究表明，在单侧前庭传入神经切断术（UVD）患者中，UVD导致的眼扭转位置变化与在其他方面黑暗的房间中短暗线的视觉感知方向之间存在密切关系（1）。然而，该结果可能已被混淆，因为UVD可能同时影响了眼扭转和关于头部相对于重力位置的感觉信息，而在进行视觉感知判断时必须使用这些信息。因此，我们寻求一种方法来测试眼扭转位置与方向视觉感知之间的关系，这种关系不会因感知到的头部位置变化的可能影响而混淆。
