Dynamics of an oscillating viscoelastic sphere: a model of the vitreous humor of the eye.
The vitreous humor of the eye is modelled as a homogeneous viscoelastic sphere. The analysis provides a relation for the displacement amplitude and phase following oscillatory and step excitations, as functions of the storage and loss moduli of the vitreous gel, and allows calculation of the resolution requirements for a non-invasive optically-based diagnostic method for the viscoelastic properties of the vitreous.
