Potential for improved diagnosis of retinal vascular diseases
Abstract
High-speed digital holography reveals local blood flow contrasts in the eye fundus through deterministic signal analysis, leveraging a forward scattering model of dynamically diffused light. This approach enables the estimation of absolute blood flow in primary in-plane retinal arteries.
