Abstract:
Hemodynamics parameters is important for diagnostics not only eye, but also systemic diseases of human vascular system. Applicability of such estimation is determined by growth of number of chronic vascular diseases nowadays. Investigations of eye-s hemodynamics can provide not only additional information about pathogenesis and probable treatment methods, but also provide opportunity of early diagnostics and are used as treatment control. Performed investigations showed validity of usage of tetrapolar method for ROG. It makes possible modelling of processes of blood filling of the eye, resulting in measured quantities of globulin and localization of investigated zone, and trustworthy rates of volume bloodflow in investigated eye area. In work the 3-layer model which components are an eyeball, eyelid and environmental tissues has been generated. The image from the anatomic atlas was used as a basis. Normalization of the size of an eyeball was carried out on anteroposterior size of an eyeball which makes 23 mm. Eyelid and an environmental adipose tissue have been simulated, being based on this size. As modelling program has been chosen crossplatform package "COMSOL Multiphysics". The carried out modelling on three-dimensional model has shown validity of application for the offered method of rheoophthalmography registration with accepted assumptions.
