Does active standing reduce wave reflection in the presence of increased peripheral resistance in young and old healthy individuals?
With standing, haemodynamic variables change similarly in older and younger individuals. The opposite changes in reflection magnitude and peripheral resistance suggest that reflection and pressure augmentation are not solely dependent on peripheral resistance.
The full-field PhNR amplitude provides a potentially reversible measure of inner retinal function that improves after IOP lowering. Further study now is required to assess its use as a measure of optic nerve health in glaucoma patients.
