“…Te children in Sydney exhibited a signifcantly lower prevalence of myopia. A Brazilian study [29] compared the initial ocular AXL of children living in the equatorial region (Aracati region) with that of children from the Campinas region located at 23 °southern latitude (421 eyes, mean age at the beginning of the study: 10.6 years) and documented a shorter ocular AXL in children from Aracati, which has greater sun exposure.…”

In recent decades, the prevalence of myopia has increased worldwide as well as in European countries, and it has become an important medical and socioeconomic problem. Our prospective single-center study analysed the changes in ocular axial length (AXL) in a population of Central European schoolchildren from 2016 to 2019. The study included 528 eyes of 264 children with a mean age of 12.2 years at the beginning of the study. Visual acuity, ocular AXL, anterior chamber depth, and the questionnaire were examined at 6-month intervals (in spring and autumn, following the winter and summer periods, respectively). The average ocular AXL was 23.329 mm (median: 23.315 mm) at the beginning of the study and 23.525 mm (median: 23.505 mm) at the end of the study. The change in ocular AXL per month was significantly higher ( p < 0.0001 ) during the winter period (average: 0.013 mm, median: 0.011 mm) than during the summer period (average: −0.001 mm, median: 0.000 mm). We observed a significantly higher increase in ocular AXL in a Caucasian population during the winter period (with lower daylight exposure) than the summer period.

Introduction: Myopia is a clinical condition that occurs when the image of a distant object is focused in front of the retina by the non-accommodating eye. The prevalence of Myopia has been getting higher for decades. A cohort study stated continuing axial elongation in adults with high Myopia. Methods: This research is a retrospective study approach. Data obtained from central general hospital Dr. Mohammad Hoesin Palembang from January 2021 to February 2022. Medical record data included in this study were patients diagnosed as myopic patients. The exclusion criteria were patients with missing medical records and any other refractive disorder. The correlation between myopia degree and axial length using ANOVA or Kruskal-Wallis H test depend on its data distribution. Data processing was performed using SPSS version 25. This study aims to determine the association between axial length and myopia degree. Results: Female patients are found predominantly (58.5%). Through the recent surveys, either the domestic or foreign population, results have stated that the prevalence of Myopia is higher in females, and other studies found that it fluctuated with age among adolescent females. The age of patients varies from 16 years to 75 years, and the mean baseline is 30.9± 3.82 years. Mild Myopia accounts most common incidence (53.1%), with laterality, which is found to be more common in the left eye (57.1%). Mean baseline axial length 21.95± 2.85 with visual acuity in LogMar 0.89 ± 0.51. There is a statistically significant difference in axial length based on myopia degree (p=0.000). Conclusion: Female patients are found predominantly in myopia patients, with the age of patients varying from 16 years to 75 years and a mean baseline of 30.9± 3.82 years. There is a statistically significant difference in axial length based on myopia degree.

“…However, among these components, more attention is paid to the axial length, which is the major parameter for both hyper myopia and myopia [ 7 ]. Furthermore, studies have shown that the alteration of environmental factors and the identification of genetic correlations may play a significant role in axial elongation, myopia progression, and future ocular complications [ 8 , 9 ].…”

Background: Myopia is a condition in which the visual images come to a focus in front of the retina of the eye. This disease is a major cause of visual disability, which presents in 108 million persons globally. Purpose: This study aims to determine the relationship between the degree of myopia, the axial length, and the choroidal thickness (CT). Methods: This is an observational analytical study that made use of a cross-sectional design. A total of 59 participants with refractive errors underwent treatment at Hasanuddin University Hospital and 116 eyes were measured and analyzed. The choroidal thickness was measured using the Enhance Depth Imaging OCT (EDI-OCT) tool, which is divided into nine observational areas. Furthermore, all data obtained were compared using statistical analysis, such as the one-way ANOVA and Pearson correlation test (p < 0.05). Results: There was a significant relationship between the choroidal thickness with axial length (p < 0.05) and myopia degrees (p < 0.05). Conclusions: The thickness of the choroid decreases with an increase in the axial length and degree of myopia, which further indicates that the higher the myopia degree, the thinner the choroidal vasculature.
