(335) Pupillary Light Responses Differ in Post-Traumatic Headache and Chronic Migraine Compared to Non-Headache Controls

Persistent post-traumatic headache (PTH) and chronic migraine (CM) often present with clinically overlapping features including prominent light sensitivity. Dynamic pupillometry is a promising new tool for evaluation of autonomically mediated responses to light in headache disorders, as they may differ between headache phenotypes. While our prior work has evaluated autonomic responses in chronic migraine and mild traumatic brain injury (aka concussion), differences in PTH and chronic migraine have not been explored.
