Аннотация:The aim of the study was to find and justify some characteristics that
can be determined in standard ophthalmologic tests and correlate with
the data on glaucoma progression degree for the eye investigated. The
analysis is based on the results we have obtained by simulating tonometric
measurements with Maklakoff and Schiotz tonometers using our
mathematical model of the eyeball.
The results testify in favor of the contemporary hypothesis about the
correlation between glaucoma severity and the level of abnormality of elastic
properties of the corneoscleral coat. It is shown that the progress of
the disease is accompanied by increase in the Schiotz pressure difference
coefficient and decrease in the similar Maklakoff coefficient. An important
additional characteristic, the ratio of these coefficients, is proposed.
Increase in this ratio with glaucoma progression corresponds to increase
in scleral stiffness simultaneously with a more significant increase in the
stiffness of the cornea.
