Torsions of the eyes and deviations of the subjective visual vertical in roll occur regularly with disorders of the central vestibulo-ocular system. Although nearly universally coexisting, torsions and deviation have been held to be more or less independent of each other.
Angles of torsion were determined from fundus photographs in 55 subjects representing a variety of acute, focal, brainstem or cerebellar lesions. Measured torsions were contrasted with quantitative measurements of the subjective visual vertical.
Torsions and deviations proved to be directly proportional, with a direction coefficient close to unity, and were strongly correlated (r = 0.86).
Torsions and deviations are strongly dependent. This result should allow the generation of a more transparent pathophysiological model. From a practical point of view, measurements of deviation appeared more robust than those of torsion.
眼球扭转和主观垂直视觉在滚转中的偏斜经常与中枢前庭眼动系统障碍有关。尽管几乎普遍共存，但扭转和偏斜被认为或多或少是相互独立的。
在代表各种急性、局灶性、脑干或小脑病变的 55 名受试者的眼底照片中确定扭转角度。测量的扭转角度与主观垂直视觉的定量测量进行对比。
扭转和偏斜被证明是直接成比例的，方向系数接近 1，并且具有很强的相关性（r = 0.86）。
扭转和偏斜高度相关。这一结果应该可以生成一个更透明的病理生理模型。从实际的角度来看，偏斜的测量似乎比扭转的测量更稳健。
