Pupillary response in those with PTSD differs from people who have not experienced traumatic events. The pupils of those with PTSD failed to show sharp constriction caused by light changes, and more enlargement when exposed to emotional stimuli that other participants. Patients with PTSD not only showed an exaggerated response to threatening stimuli but also to stimuli that depicted positive images.
