Stimulation of the vestibular system by angular acceleration produces widespread sensory and motor effects. The present study was designed to study a motor effect which has not been reported in the literature, i.e., the influence of rotary acceleration of the body on ocular accommodation. The accommodation of 10 young men was recorded before and after a high-level deceleration to zero velocity following 30 s of rotation. Accommodation was recorded continuously on an infrared optometer for 110 s under two conditions; while the subjects observed a target set at the far point, and while they viewed the same target through a 0.3-mm pinhole. Stimulation by high-level rotary deceleration produced positive accommodation or a pseudomyopia under both conditions, but the positive accommodation was substantially greater and lasted much longer during fixation through the pinhole. It is hypothesized that this increase in accommodation is a result of a vestibular-ocular accommodation reflex.
角加速度对前庭系统的刺激会产生广泛的感觉和运动效应。本研究旨在研究一种文献中尚未报道的运动效应，即身体旋转加速度对眼调节的影响。在10名年轻男性旋转30秒后进行高速减速至零速度前后，记录他们的眼调节情况。在两种条件下，使用红外验光仪连续110秒记录眼调节情况：受试者观察远处设置的目标时，以及他们通过0.3毫米针孔观察同一目标时。在两种条件下，高速旋转减速刺激均产生了正性调节或假性近视，但通过针孔注视时，正性调节幅度明显更大且持续时间更长。据推测，这种调节增加是前庭-眼调节反射的结果。
