Valuation of the Extraocular Effective Elastance on the Base of Dynamical Model

This paper makes an attempt to answer the question for the effective (functional) value of extraocular elastance. Here, this question is connected with the problem of rhythmicity mechanism of nystagmus phenomena. A likely dynamical model of the nystagmus horizontal motion is proposed by application of the energy and moment of momentum conservation laws to the extraocular muscle. The model is investigated qualitatively and numerically on the base of existing experimental data in the literature. On the base of analysis of obtained results a hypothesis is formulated that the nystagmus horizontal motions present self-oscillations of the considered system.
