We herein report a patient with the abnormal eye movement characterized by a conjugate slow-upward eye movement followed by a fast-downward movement to the primary position (slow-upward ocular bobbing). A 55-year-old man with a 12 years' history of striatonigral degeneration developed pneumonia and was admitted to our hospital. ⋯ This spontaneous eye movement was recognized throughout his stay in the hospital, irrespective of his consciousness level. Although other forms of ocular bobbing/dipping are usually associated with the loss of consciousness, all three reported patients with this slow-upward ocular bobbing were awake and responsive, therefore, suggesting a different kind of background pathophysiology in this unique eye sign.
