After observing an involuntary response in pupils as a result of pain or medication, a device was developed that "measures a patient’s pupillary response and, using proprietary algorithms, provides a diagnostic measurement of pain intensity, pain type and, after treatment is administered, monitors efficacy." The traditional method for measuring pain involves a 0 to 10 scale that is subjective and self-reported. This approach increases the chances for misdiagnosis, over-treatment or under-treatment since it is not objectively measured. Benefits for this new approach include [...]
