The PUPIL Study - Automated, Quantitative Pupil Assessment Using Binocular OCT

Participants in the study will undergo pupil measurement using a prototype binocular OCT imaging system (Envision Diagnostics, Inc., CA). For the binocular OCT imaging system, testing will be performed twice in the same session, by the same examiner, to allow assessment of repeatability (test-retest variability).

Participants in the study will undergo pupil measurement using a validated, commercially available pupilometer (RAPDx; Konan Medical USA, Inc., Irvine, CA).
