Features of the Development of Anatomical and Optical Eye Media in Children of Turkmenistan

One of the main causes of visual impairment in children is visual impairment (myopia, hypermetropia, astigmatism), which are associated with refraction, and affect visual performance and school performance of children, as well as have a negative impact of binocular vision disorders.

Purpose: To study the peculiarities of the development of individual eye structures in preschool and school-age children.

Materials and methods. 5896 children (11 582 eyes) of preschool and school age (1–14 years old) were examined. Healthy children were examined. All children underwent a comprehensive clinical and instrumental ophthalmological examination, which included: visometry, biomicroscopy, refractometry, ophthalmoscopy, tonometry, pachymetry, ultrasound biometry and ophthalmometry.

Results. As a result of the study, the dynamics of eye development in children was studied depending on age, the eye parameters, clearly change and the growth of the eyeball ends by the age of 14. It was found that in children aged from 1 to 14 years vision, refraction, anterior-posterior axis length, lens thickness, anterior chamber depth and vitreous volume significantly increased, and accurate indicators were obtained.

Conclusion. The data obtained make it possible to understand the dynamics of the development of the eyeball in preschool children and help in predicting the occurrence of various pathologies and their prevention. The conducted studies have shown some differences in the anatomical and optical environments of the eyes in children of Turkmenistan, whose climatic conditions in evolution led to the development of an adaptive mechanism that determined the corresponding parameters of the organ of vision and its ethnic peculiarity. Based on a large number of studies (5896 children), specific sizes of anatomical and optical eye media in children of Turkmenistan have been established.
