title: [Role of mechanical properties of the external ocular membrane in the dynamics of intraocular pressure].
abstract: Changes of the intraocular pressure in alterations of the central arterial pressure are an accepted fact. Disbalance of the above changes occurring at that is considered to be a display of active regulatory mechanisms. In this study, comparison of the pulse waves and short--term changes of arterial pressure with oscillations of the intraocular pressure occurring at that, has been made. Analysis of all the changes was made with the aid of a mathematical model. Amplitude--phasic characteristics of the eye membrane were studied for ascertaining of effect of different factors on the amplitude and form of the intraocular pressure pulse waves. In experimental conditions, the differences in dynamics of the level and in form of the pulse oscillations between the central arterial and the intraocular pressures were shown to be due not to functioning of active regulatory mechanisms but to the elastic--viscous features of the eye membrane.
