Modelling the transmural transport of oxygen to the retina

摘要

Oxygen transport from retinal capillaries to retinal tissue is studied by use of a Krogh-type cylinder model. The retinal tissue is represented as an array of uniformly cylinders with capillaries along the axes. The model introduces the transmural transport of oxygen from the retinal capillaries to its surrounding (retinal) tissue in a hypoxia environment. Computational results for concentration distribution in the retinal tissue are presented through graphs and the effects of important model parameters: intraocular pressure, capillary wall permeability coefficient, capillary wall pressure gradient constant on the oxygen concentration distribution are depicted and discussed.
