[Correlation of chorioretinal parameters with anatomical, optical and functional indicators of eyes with amblyopia of various origins].

Unlabelled: Purpose. To measure thickness of the central retina and choroid, retinal nerve fiber layer and ganglion cell complex in the macular region, retinal nerve fiber layer in the peripapillary region in eyes with various types of amblyopia, and to analyze its relationship with best corrected visual acuity, refraction and axial eye length.

Material And Methods: The study included 50 patients aged 5 to 16 years (mean age 10.

[Correlations between visual fixation parameters, photosensitivity of the retina and visual acuity in various types of amblyopia].

Purpose: To study the parameters of visual fixation, photosensitivity in the macular region of the retina, and their correlation with the best-corrected visual acuity (BCVA) for various types of amblyopia.

Material And Methods: The study included 50 patients with an average age of 11.02±4.

[Choroid and optical defocus].

The review summarizes experimental and clinical data attesting to the important role the choroid plays in the development of refraction through optically oriented thickness changes and the release of growth factors. Because of its unique anatomical position, the choroid can influence the transmission of a cascade of chemical signals from the retina to the sclera and thereby affect the growth of the eye. Understanding the relationship between the optical defocus and the response of the choroid to it will help uncover the fundamental mechanisms for controlling eye growth and develop new strategies for preventing the progression of myopia.

[Long-term results of perifocal defocus spectacle lens correction in children with progressive myopia].

Unlabelled: Peripheral defocus plays a significant role in the formation of refraction. Perifocal spectacles allow differentiating correction of central and peripheral refraction of the eye along the horizontal meridian and can correct or reduce peripheral hyperopia.

Purpose: To study the long-term results of wearing perifocal spectacles on the refraction in children with progressive myopia.

[Peripheral refraction and retinal contour in congenital and acquired high myopia].

Aim: to perform a comparative study of peripheral refraction and retinal contour in patients with congenital versus acquired high myopia.

Material And Methods: A total of 30 patients (60 eyes) with high myopia aged 8 to 18 years (11.2±0.
