Pupillometry systems for measuring one or more pupillary characteristics of a patient are shown and described. The puillometry systems include at least one camera for capturing image data of one or snore pupils, at least one radiation source configured to project radiation to the one or more pupils, and a computer system in data communication with the at least one camera, the computer system having a processor and a non-transitory computer-readable storage medium. The non-transitory computer-readable storage medium includes computer-readable instructions for collecting and time stamping the image data, identifying and measuring the one or more pupils in the image data, processing the image data to produce measurement data of change in the one or more pupillary characteristics, and calculating a standardized output of measurement data for the one or more pupillary characteristics.
