| Summary: | Eye movements have been shown to be altered in neurological disorders with eye-tracking technology, and thus it has been recently proposed to use them as biomarkers for their early diagnosis. The eye-tracker EyeLink 1000 Plus is the current Gold Standard to record eye movements but has some limitations to be used in a clinical environment. The purpose of this work was to compare the performance of a new, less complex eye-tracker, the Tobii Pro Spectrum, with the EyeLink 1000 Plus for screening purposes. To do so, both eye-trackers were used to record eye movements of 10 participants when performing several visual tasks (saccades, smooth pursuit and fixation). A software was implemented to display the visual stimuli on a screen and to acquire and process the data with the Tobii Pro Spectrum. The results and the statistical analysis carried out suggest that both eye-trackers provide similar data for most of the parameters analysed, meaning that the Tobii Pro Spectrum is a useful tool to record eye movements with a precision similar to that of the Gold Standard and thus, that it could be used for clinical analyses. |
