DYNAMIC BEHAVIOR OF EYE GLOBES.
Abstract
The eye globe was treated as a spherical shell (combined cornea and sclera) filled with (vitreous and aqueous) and surrounded by (tissue and fat) incompressible, inviscid, irrotationally flowing fluids. Its dynamic behavior was investigated by making use of the Flugge shell equations and the appropriate inertia terms. The axisymmetric case was solved in closed form, and the asymmetric case was solved numerically. Some qualitative results for physiologically meaningful parameter values are given. Static and dynamic experiments were performed on enucleated dog eyes. The static experiment measured the change in volume of the eyes as a function of time at various pressures. The results of this experiment indicated that the eyes were viscoelastic with an associated time constant of approximately 20 minutes. (Author)
