It is demonstrated that eye formation in ontogenesis is accompanied by thickening of all scleral regions, especially the posterior region, accumulation of collagen and elastin in the posterior pole par excellence, a reduced share of soluble collagen fractions, a lower content of glycosaminoglycanes in the equatorial region and an increase of tensile strength and elasticity module. The authors distinguish a so-called group of risk marked by a reduced content of collagen in the posterior scleral region as well as a delayed decrease of its soluble fractions with age in the posterior and in the equatorial regions and a diminished tensile strength.
