Abstract:
Several studies of patients with chronic cervical pain and chronic whiplash syndrome report a high frequency of oculomotor function derangements pointing towards brainstem involvement and/or default sensory input from neck afferents. In light of these reports, it seems important to investigate other patient groups with similar upper cervical spine disorders. In this study, voluntary eye motor performance was evaluated in 11 rheumatoid patients (RA) with upper cervical dislocation and a clearly noticed joint affection of the cervical spine. The results were compared with 6 RA patients without cervical engagement and normal individuals. Nine of the 11 patients with atlanto-axial dislocation showed pronounced oculomotor disturbances of smooth pursuits compared with only minor changes in the control group. The pattern of oculomotor dysfunction in patients with rheumatoid cervical dislocation indicates brainstem involvement, which may be an early sign of brainstem affection/myelopathy.
