Low or high sympatho-adrenal-medullary axis (SAM) and hypothalamic-pituitary-adrenal axis (HPA) dysregulation reflect chronic stress. Retinal vessel dynamics may relate to SAM, HPA activity and stroke risk. Our objectives were therefore to assess the relationships between retinal vessel, SAM and HPA responses, and to determine stroke risk. A prospective bi-ethnic gender cohort ( = 275, 45 ± 9 years) was included. Urine/serum/saliva samples for SAM [norepinephrinecreatinine ratio (u-NE)] and HPA [adrenocorticotrophic hormone (ACTH), co
