Eye tracking has become a valuable method to study performance and cognition in diverse settings. For the present paper, we reviewed the literature on eye tracking in anesthesiology and identified nine publications. We have summarized the method and results of these publications. Further, we identified and discussed several methodological issues that occur when conducting eye tracking in anesthesiology, such as sample size, large data loss, and differences in study settings. Finally, we suggest future research topics in anesthesiology, which may particularly benefit from eye tracking.
