The optical model of polycrystalline networks of histological sections of rectum wall is suggested. The results of investigating the interrelation between the values of statistical (statistical moments of the 1st-4th order) and correlation (cross correlation coefficients) parameters are presented. Such parameters characterize the coordinate distributions of the fourth parameter of the Stokes vector of Fourier transforms of laser images of myometrium tissues. The diagnostic criteria of myometrium pathologies are determined.
