Pupillary Dilation Reflex in Healthy Volunteers | NCT07746167

NCT07746167

Overview

NCT ID: NCT07746167
Lead Sponsor: Children's National Research InstituteOTHER
Official Title: The Relationship Between Neurostimulation Intensity and Pupillary Dilation Reflex (PRD) in Healthy Volunteers
Brief Summary: This a single site, observational study that will examine how the pupil responds to neurostimulation under different conditions in healthy adults. The objective is to measure pupillary dilation reflex (PRD) in response to increasing neurostimulation intensities using the AlgometRx device.
Conditions: Healthy Participants
Interventions: No intervention (observational study)

Ages Eligible for Study: Adult (18-64)
Sexes Eligible for Study: All
Accepts Healthy Volunteers?: Yes
Eligibility Criteria: Inclusion Criteria:

Age 18-60 years.

In good general health (self-reported).

Able and willing to provide written informed consent.

Exclusion Criteria:

Eye pathology that prevents accurate pupillometry.

Pregnancy (Self-Report)

Diagnosis of autoimmune disorders.

Diagnosis of any neuropathic disorder

Inability to complete questionnaires.
