Inner ocular blood flow response to exercise in healthy humans

Abstract

Inner ocular circulation consists of choroidal and retinal circulation. The inner ocular blood flow nourishes the retina, which plays an important role in vision. It had been thought that inner ocular circulation kept its blood flow constant against circulatory challenges during exercise. Recent studies, however, have revealed that inner ocular blood flow changes during exercise, and that retinal and choroidal circulations show different responses depending on the manner of exercise. This review provides an overview of the responses in inner ocular blood flow to exercise and its relevant factors.
