    Rotary acceleration significantly impacts vision, causing temporary pseudomyopia. This vestibular-ocular accommodation reflex was more pronounced when viewing through a pinhole.

    Area of Science:

    • Neuroscience
    • Ophthalmology
    • Vestibular System

    Background:

    • Angular acceleration of the vestibular system causes known sensory and motor effects.
    • The influence of rotary acceleration on ocular accommodation has not been previously studied.

    Purpose of the Study:

    • To investigate the effect of body rotation and deceleration on ocular accommodation.
    • To explore a potential vestibular-ocular accommodation reflex.

    Main Methods:

    • Ten young men underwent high-level rotary deceleration after 30 seconds of rotation.
    • Ocular accommodation was measured using an infrared optometer before and after deceleration.
    • Measurements were taken while subjects viewed a far point target, both directly and through a 0.3-mm pinhole.

    Main Results:

    • Rotary deceleration induced positive accommodation (pseudomyopia) in both viewing conditions.
    • The induced positive accommodation was significantly greater and longer-lasting when viewing through the pinhole.
    • This suggests a strong vestibular influence on the accommodative system.

    Conclusions:

    • High-level rotary deceleration can transiently alter ocular accommodation, inducing pseudomyopia.
    • The vestibular system appears to influence ocular accommodation, potentially via a vestibular-ocular accommodation reflex.
    • Pinhole viewing enhances the manifestation of this vestibular-induced accommodative response.
