Does EyeKinetix pupillometry clarify RAPD detection?

Objective pupillometry without dark adaptation using the EyeKinetix device displays substantial variability and identifies a number of relative afferent pupil defects (RAPDs) in this cohort of healthy patients. These findings indicate that, in healthy populations, reliance on RAPDx scores alone could generate false positives. Establishing robust normative cutoffs and validating them in disease cohorts will be necessary before reliable use as a screener. Further optimization may be necessary for more clinical confidence in a primary care setting.
