U.S., Aug. 7 -- ClinicalTrials.gov registry received information related to the study (NCT07748936) titled 'Chorioretinal Imaging, Vascular Biomarkers, and Ultra-Trail: A Pilot Study' on July 28.
Brief Summary: Retinal and choroidal microcirculation is a relevant biomarker of systemic vascular health and lies at the heart of eye-heart interactions. Noninvasive retinal imaging, particularly OCT angiography (OCT-A), now makes it possible to examine retinal and choroidal microvascularization in vivo and to study its relationship with systemic cardiovascular and neurovascular mechanisms.
Ultra-endurance activities, such as ultra-trail races, induce significant systemic hemodynamic changes, including dehydration, variations in perfusion pressu...
