About this study

This trial is testing a new way to diagnose and monitor treatment for light sensitivity, headaches, traumatic brain injury, by measuring facial features, pupil responses, retinal electrical responses, and autonomic nerve responses to light. It uses devices like wrist-watch sensors and OCT scans.

Based on ClinicalTrials.gov records.
