Abstract
• Ocular movement was studied in 19 patients with Parkinson's disease and in ten normal controls. Common abnormalities included "hypometric saccade" on the eye-tracking test and on command, "saccadic pursuit," and convergence paresis. Reaction time was longer in patients with Parkinson's disease than in controls for horizontal saccadic gaze, finger movements, and body movements. Maximal saccadic velocity of horizontal gaze was slower in patients with Parkinson's disease than in controls. Slowing of the horizontal saccadic movement correlated significantly with an increased reaction time of finger and body movements. Correlation of decreased saccadic velocity with increased reaction time of finger movement was found for the finger ipsilateral to the direction of horizontal gaze, but not for the contralateral finger. It is postulated from these facts that bradykinesia also exists in eye movements in Parkinson's disease.
