#### Abstract

The work examines a linear axisymmetric model of the eyes pulse blood flow. The main purpose of the model is the determination of mathematical dependence of linear changes in the eye thickness of vascular layer with the pulse. The main parameter is the volume of the input eye pulsation of blood flow. Ocular hemodynamic parameters depend from various individual anatomical values of a patient's eye. In the paper all assumptions of axisymmetric model are described. Calculations of the mathematical dependence equation are based on geometric parameters of the eyeball. The analytical expression of volume changes in the measuring ophthalmoplethysmography is presented. Accordance to our calculations, linear change in the eyeball layers thickness varies within tens and units of microns after the input blood pulse volume. Advanced technical methods that can register such a small range of length units are considered. Such a registration and subsequent analysis of micro-displacement data will allow diagnosing different pathological states of the eye hemodynamic in ophthalmology and neurology.
