Abstract
Doppler holography, employing high-speed digital imaging and near-infrared light, maps blood flow in the eye's fundus. It can be exploited to estimate quantitatively the velocity and volume of blood flow by assessing the Doppler frequency broadening increase in retinal arteries with respect to local surrounding tissue. This technique enhances our ability to gauge hemodynamics within these arteries across the cardiac cycle, crucial for ocular disease diagnosis and management. Infrared radiation scatters and broadens within the retina's deeper layers, aiding the analysis of blood flow in superficial retinal vessels. Light interaction with blood scatterers is quantified to estimate flow velocity, using a model of forward scattering for momentum transfer. The root-mean-square velocity reflects the degree of Doppler broadening, allowing for a detailed assessment of retinal hemodynamics. This approach provides a valuable tool for analysing ocular vascular health.
