Eye–tracking tasks engage both smooth pursuit and saccadic gaze movements. Performance of these different types of gaze movement during simple visual tasks, can indicate deficits in memory and executive functions. Similarly, changes in pupillary reflexes have been shown to reflect mental effort and cognitive processes. We hypothesised these non-invasive eye-tracking signals will predict verbal memory performance in patients with drug-resistant epilepsy.Twenty-nine patients completed simple eye-tracking tasks, probing Smooth Pursuit (SP) and Anti-Pro-Saccade (AP) gaze movements, and were grouped according to their performance in a Free Recall (FR) verbal memory task. We analysed the dynamics of gaze movement and pupil dilation in SP using saccade rate, normalised pupil area, gaze velocity gain and position error, and in AP using count of correctly completed pro- and anti-saccade trials, mean pupil area, and saccade latency.We found significant differences in these measures between the groups of patients with normal or impaired verbal memory performance in the FR task. In case of the SP task, the rate of saccades per second emerged as the most significant differentiating factor (p<0.0001) of the FR performance. In the more complex AP task, significant differences between the good and poor FR performance were observed for the correct trial count (p<0.0001) and for the mean latency of saccade initiation (p=0.03).Our results show that poor performance in the gaze-tracking tasks indicates deficits in verbal memory tasks. We propose that simple eye-tracking features can provide biomarkers for memory and cognitive impairments in epilepsy and potentially other brain disorders.
