Summary: The prevalence of myopia is high among Japanese schoolchildren, with almost half of preschoolers being myopic. The time spent using digital devices is positively associated with lens thickness, while reading time is negatively associated with lens thickness, spherical equivalent, axial length, and vitreous chamber depth.

Summary: The study revealed that during the COVID-19 lockdown, there was an increase in myopia prevalence and axial length in school children, and these impacts persisted one year after the lockdown.

Summary: In this study of elementary school-aged children in Singapore, various sleep factors such as quality, duration, timing, and consistency were not independently associated with myopia, spherical equivalent, and axial length. Large longitudinal studies are needed to verify these results.

Summary: The pattern of ocular axial growth differs among different age groups, with body height showing a positive correlation with axial length growth and myopic shift in refractive error.

Summary: This study investigated the differences in accommodation-induced axial elongation between myopic and nonmyopic children. The results showed that myopic children exhibited significantly greater accommodation-induced axial elongation than nonmyopic children. This finding could support a potential mechanism linking near work, axial elongation, and myopia development in children.

Summary: Unilateral orthokeratology lenses effectively reduced axial elongation in the more myopic eyes and reduced interocular AL differences in children with myopic anisometropia. The refractive state of the untreated eyes did not affect the axial elongation of the more myopic eye wearing the orthokeratology lens. In the untreated eyes, AL increased faster in the low myopia subgroup than in the emmetropia subgroup.

Summary: This study aimed to investigate the cutoff of axial length (AL) change in order to accurately differentiate between progressive and non-progressive myopic children. The results showed that myopic children with non-progressive status had significantly less axial elongation than those with progressive status. An annual AL change cutoff of 0.20 mm/year can be used to differentiate between non-progressive and progressive myopia.

Summary: This study aimed to investigate the impact of refractive error, age, gender, and parental myopia on axial elongation in Chinese children and provide normative data for the population. The results showed that axial elongation decreased with age, with different effects depending on the refractive error group. Myopic children had higher axial elongation compared to emmetropic and hyperopic children, but these differences decreased as they grew older.

Summary: This study aimed to assess the association between axial length/corneal radius ratio (AL/CR ratio), axial length (AL), and refractive status, and evaluate their accuracy for myopia assessment in Chinese children. The results suggested that the AL/CR ratio may be an alternative indicator for myopia assessment in children, and combining demographic factors with the AL/CR ratio can improve the accuracy of the assessment.

Summary: The study found through a double-blinded randomized clinical trial that violet light-transmitting eyeglasses (VL glasses) have a suppressive effect on myopia in children, particularly in those with shorter near-work time and those who had never worn eyeglasses before the trial. The axial elongation suppressive rate in the VL glasses group was 21.4% over two years.

Summary: This study investigated the correlation between baseline axial length (AL) and axial elongation in myopes undergoing orthokeratology (ortho-k). The results showed a negative association between axial elongation and baseline AL in the ortho-k group. Furthermore, children aged 8-11 years with longer baseline AL demonstrated slower annual axial elongation during the first 2 years of ortho-k treatment.

Summary: This study aimed to investigate the association between choroidal thickness and age, axial length, and refractive errors in Chinese adults. The results showed that choroidal thickness decreased with age after 50 years, and the thinning was more prominent in the central and parafoveal regions as axial length increased. The correlation between choroidal thickness and age and axial length varied among different groups with different refractive errors.

Summary: This study assessed the impact of patient age on measurement variability for axial length measurements taken with different instruments. The results showed that axial length measurements with the IOLMaster 700 were significantly longer and less variable compared to the IOLMaster 500. However, patient age had no effect on the variability of axial length measurements.

Summary: This study analyzed the relationship between diopter and choroidal thickness in myopic children and found significant differences in choroidal thickness among myopic children. Choroidal thickness was positively correlated with diopter and negatively correlated with axial length. Therefore, choroidal thickness is considered an important indicator for evaluating the progression of myopia.

Summary: This study found that the prevalence of myopia increases with age and grade in school children. The results suggest that exposure to schooling, rather than age, appears to be the major driver of refractive development, at least in the early years of schooling. Interventions during this period, involving reductions in educational pressure and increased time outdoors, may have significant effects on the subsequent development of myopia.
