Figure 2From: Subthalamic deep brain stimulation improves smooth pursuit and saccade performance in patients with Parkinson’s diseaseA Saccade eye movement velocity (mean and SEM) for three saccade amplitudes with DBS OFF and ON. B: Saccade amplitude accuracy in percentage (mean and SEM) with DBS OFF and ON. A value of 100 represents perfect saccade amplitude accuracy whereas values below 100 represent short saccades (hypometric) (# denotes P < 0.1; * denotes P < 0.05; ** denotes P < 0.01 and *** denotes P < 0.001).Back to article page
