Осевая длина глаза у пожилого населения Южного Урала (по данным исследования «Ural Very Old Study)

Abstract

Intrоduction. Various biometric indicators of the eyeball in certain categories of the population continue to be the subject of research and discussion among specialists. At the same time, the information provided by different authors regarding the normal values of the length of the axial length of the eye is quite contradictory, while the norm indicators in certain population groups and subgroups are of great value. This fact was the reason for the present study. Material and methods. Between 2017 and 2020 The Ufa Eye Research Institute conducted a descriptive and analytical population study Ural Very Old Study (UVOS), in which 1526 participants took part. Results. The axial length of the eyeball in the population of the Republic of Bashkortostan (RB) aged 85 years and older is, on average, 23.11±1.08 mm. The conducted multivariate linear regression analysis showed the most statistically significant association of axial length (cumulative coefficient of determination R² =0.70) with factors such as height (p<0.001), level of education (p=0.002), refractive power of the cornea (p<0.001), spherical refractive error (p<0.001). Conclusion. The morphometric and correlation features of the length of the anterior-posterior axis of the eyeball revealed in the UVOS study determine the presence of regional specificity of the anatomical and nosological characteristics of the organ of vision in the population of the Republic of Bashkortostan aged 85 and older. Key words: axial length, population study, year 85 and older
