Retinal Microcirculation Disorder Clinical Trial
Official title:
The Influence of Daily Activities on Retinal Microcirculation in Normal Adults
The daily behaviors such as drinking coffee, wine, reading, exercise and body postural changes may have influence on the function or morphology of the retinal microcirculation in healthy people.A recent study found that the fingertips microvascular bed constricted obviously after the intake of a cup of coffee with caffeine, it significantly reduced blood flow to the fingers; Long reading of electronic products can induce significant dry eye symptoms, affect visual quality, and cause asthenopia. Microcirculation is critical for regulating vascular resistance and blood flow in organs. Fundus blood vessels is the only visible microvascular in vivo, its morphology and function changes not only associated with eye disease, but also with cardiovascular and cerebrovascular diseases. Optical coherence tomography angiography (OCTA) is a new technique which could acquire blood flow information in a non-invasive way without the use of dye. Magnetic resonance imaging (MRI) can quantitatively evaluation of cerebral blood flow and retina-choroid blood flow using the noninvasive arterial spin labeling technique in a large field of view (FOV) without depth limitations.The study tried to detect the influence of daily behaviors such as drinking coffee, red wine, reading ,and exercise on the retinal microcirculation with OCTA and MRI, and provide reference for health behaviors.
