Abstract

There were examined 136 patients with progressive myopia (192 eyes) in the main group and 113 patients (113 eyes) with stationary myopia. The age of patients is from 8 to 17 years, mean age is (12,5 ± 0,07) years. The observation period is from 1 to 7 years. We also examined 46 patients with emmetropia (46 eyes) and 30 patients with low-grade hyperopia (30 eyes) from 6 to 17 years. It was established that the progression of myopia is characterized by an increase in the anteroposterior size of the eye, a decrease in the thickness of the sclera, a decrease in the corneal hysteresis and rigidity of the corneoscleral membrane is accompanied in 83,3 % of cases by an increase in intraocular pressure to the upper norm and above, which eventually leads to an increase in the strain of the corneoscleral membrane, a decrease in the biomechanical properties of the sclera and the progression of myopia.

Keywords
