In order to maintain visual fixation, the oculomotor muscles are controlled by reflexes arising from the complex interaction between the vestibular apparatus, the perception of slippage of the target image on the retina and, significantly, by the proprioceptive mechanisms of the cervical spine; the cervico-ocular reflex (COR). Chronic neck dysfunction, particularly in whiplash patients, has been associated with modifications in eye movement behaviour. The nature of this association is poorly defined, although previous studies on individuals with post-whiplash syndrome have noted such things as delayed high speed eye movements following immobilisation in a cervical spine collar; altered capabilities of pursuit when following a target; increased gain (amplitude of movement with reference to input movement) of the COR and alterations in the ability to accurately fixate on target positions. Much of the previous literature has reported qualitative changes in passing, sometimes hampered by the limits of technology employed in the experimentation, and often by repeated measures on a few individuals; accordingly, the precise nature of the COR in the presence of cervical dysfunction requires further description. The purpose of this study was to define the precise nature of the influence of the COR on eye movement in a large cohort and to describe any changes that may be present in patients with whiplash or other types of neck dysfunction.
