Towards a full model for ocular biomechanics, fluid dynamics, and hemodynamics

Lorenzo Sala, Christophe Prud'Homme, Marcela Szopos, Giovanna Guidoboni

Abstract


This contribution presents an ongoing work to implement a patient-specific mathematical virtual simulator for the eye. The aim is to create a multiscale and multiphysics model for the description of ocular biomechanics, fluid dynamics, and hemodynamics. This instrument may serve to illustrate and estimate some clinically relevant parameters, as well as predict their spatial and temporal evolution adopting forward-looking numerical techniques.
