As part of the search for a bioengineering model of the eye, the interaction between instantaneous changes of pressure in the anterior and vitreous chambers are studied. A description of the experiments as well as data evaluation is given. The results indicate a linear relationship between the chambers and a diaphragm effect of the system lens-iris-zonula-ciliar body.

A description of the experiments of the mechanical behavior of the vitreous body is presented. The experiments were performed with a photoelastic material surrounding both rabbit and human eyes. The results show that the vitreous body transmits forces isotropically as any newtonian fluid. Tests done on rabbits' eyes with a previous vitrectomy agree with the previous statements. Finally, a hypothesis of the effect of pressure on the posterior pole in myopia is given, stressing the changes clinically observed.
