[Optical aberrations of the eyes with various degrees of myopia].

Unlabelled: Purpose - to comparatively analyze the wavefront aberrations and biometric parameters of the eyes with various degrees of myopia.

Material And Methods: The study included 134 eyes of 67 patients with mild, moderate and high myopia aged 7-28 (mean age 19.3±1.

[The influence of different means of myopia correction on peripheral refraction depending on the direction of gaze].

Introduction: Peripheral defocus was experimentally found to control the development of refraction.

Purpose: To evaluate peripheral refraction (PR) of myopic eyes in terms of different means of correction and the direction of gaze.

Material And Methods: The study examined 128 patients (256 eyes) aged 8-14 years (average 11.

[Peripheral refraction and retinal contour in children with myopia by results of refractometry and partial coherence interferometry].

Objective: To determine the posterior pole contour of the eye based on the relative peripheral refractive error and relative eye length.

Material And Methods: A parallel study was performed, which enrolled 38 children (76 eyes) with myopia from -1.25 to -10.

[Correlation between biomechanical properties of the corneoscleral tunic and stereometric parameters of the optic nerve head in congenital and acquired myopia].

The correlation between biomechanical properties of the corneoscleral tunic and stereometric parameters of the optic nerve head in children and adolescents with congenital and acquired myopia has been studied comparatively. The results showed that in children with high myopia, congenital or acquired, the corneoscleral parameters (scleral echodensity at the equator and the posterior pole, corneoscleral hysteresis, cornea resistance factor, and ocular rigidity coefficient) are lower than those in emmetropes. Moreover, the corneoscleral biomechanical characteristics affect the optic nerve head parameters.

[Acoustic density of sclera as a prognostic factor of peripheral vitreochorioretinal degenerations in myopia: results of 10-years follow-up].

Prognostic value of acoustic density of sclera (ADS) is studied in development of peripheral vitreochorioretinal degenerations (PVCRD) in myopia. Children aged 8-10 years old with noncomplicated high and moderate myopia were divided into two groups after ADS measurement: 1 with ADS < or = 39dB - unfavorable prognosis, 2 with ADS >39dB - favorable prognosis. Follow-up during 10 years with examinations twice a year confirmed prognosis accuracy: in the 1st group PVCRD developed 2.
