Numerical simulations of fluid pressure in the human eye

摘要

In this article we present computational results for the pressure in the human eye. Pressure computations for different flow rates of the aqueous humor, viscosity of the aqueous humor, and permeability of the trabecular meshwork are given. The fluid flow is assumed to be axisymmetric, and modeled as a coupled system of Stokes and Darcy fluid flow equations, representing the fluid flow in the anterior cavity and trabecular meshwork, respectively. Rewriting the problem in cylindrical coordinates reduces the 3-D problem to a problem in 2-D. Computations are also given for varying angles between the base of the iris and the trabecular meshwork.
