Visual disorders are one of the common side problems in Cerebral Palsy (CP) being reported with an incidencebetween 50% to 90% of the cases. These visual disorders may interfere with the developmental process and motorlearning of these children. This work presents a robust method to spatio-temporally characterize the ocularmotion in CP. Smooth pursuit and saccadic eye tasks were assessed by using simple visual stimuli and recordingthe eye trajectories during the task. A dense optical ow estimation of the ocular movement is modulated by avisual attention model which extracts relevant eye motion information. Analyses in time and frequency domainwere performed suggesting statistical differences (p-value < 0.01) in Signal to Noise Ratio (SNR) and Waveletcoefficients for both saccadic and smooth pursuit tasks.
