An electrical model of the human eye. I. The basic model.

M. .any physical systems, hydrodynamic, mechanical, acoustical, and electrical, are analogous. This article is concerned with the development of an electrical model which is analogous to the hydrodynamic and mechanical properties of the human eye. In general, changes in these properties of the eye, occasioned by any test, procedure, or altered physiology should be matched or reproduced by this electrical model within the limits of its error. If there is no correspondence, either our present concepts of the mechanism of the action of the eye or the experimental data regarding its fundamental properties are faulty. This model then allows us to test the validity of concepts and data by comparing the model's action with the action of the eye during clinical or experimental tests. Because the model performs in a time continum 60 times faster than the eye, and
