Summary: This study investigated the prevalence and associated factors of anisometropia in school-aged children in Shandong Province, China. The results showed that ocular parameters and lifestyle parameters were associated with the occurrence of anisometropia, including differences in axial length, habitual visual acuity, corneal astigmatism, stereoacuity, indoor near work time, and outdoor activity time. Preventing myopia and treating anisometropic amblyopia early may be effective in reducing the prevalence of anisometropia.

Summary: The prevalence of myopia and visual impairment caused by myopia in Bulgarian school children is evaluated in this study. The results show a high prevalence of myopia, with factors such as age, geographical location, and school profile influencing the prevalence. Gender, adolescence, and parents with impaired vision are identified as risk factors for higher odds of myopia. Residence in a small town and engagement in daily sport activities are associated with lower odds of myopia.

Summary: This study systematically evaluated the treatment effects of multifocal lenses (MFLs) on controlling the progression of myopia in school-aged children. The results showed that MFLs had a positive effect in slowing down myopic progression in both 6-month and annual-visit trials, with sustained effects up to 36 months. However, a slight decrease in treatment effect was observed after the first visit in the 6-month trials, and a slight rebound effect was observed at the following visits. The treatment effects were more profound in annual visits, particularly in spherical equivalent refraction (SER). Therefore, long-term treatment with annual visits is encouraged for MFLs users.

Summary: This cross-sectional study aimed to determine the prevalence and pattern of co-sleeping among parents of children aged 5-12 years, as well as the associated sleep problems. Out of 275 children, 97.8% co-slept, with 48.7% bed-sharing and 51.3% room-sharing. Factors such as child's age and socioeconomic status were found to be associated with bed-sharing, and children who bed-shared were more likely to experience wake-up resistance and night terrors.

Summary: Objectives: This study aimed to investigate the epidemiological characteristics and influencing factors of myopia, providing a scientific basis for its prevention and control. Methods: A total of 7,597 students in grades 1-3 were followed up with annual eye examinations and questionnaire surveys from 2019 to 2021. Logistic regression analysis was used to identify the influencing factors of myopia. Results: The prevalence of myopia increased from 23.4% in 2019 to 41.9% and 51.9% after 1 and 2 years of follow-up, respectively. Factors associated with myopia included outdoor activities, sex, age, baseline spherical equivalent refraction (SER), parental myopia, sleep time, and digital device exposure. Conclusion: The rapid increase in myopia prevalence highlights the importance of promoting healthy habits and outdoor activities for myopia prevention and control.

Summary: The study found that school-aged children who develop myopia before the age of 10 are at risk for developing high myopia, with girls stabilizing their myopia slightly earlier than boys. Children with spherical equivalent larger than -4 D before the age of 10 have an 89.0% risk of developing high myopia at age 16, while children with spherical equivalent between -0.5 D and -2 D still have a 34% risk.

Summary: This study developed age-specific and gender-specific reference percentile charts for axial length (AL) and AL/corneal radius of curvature (AL/CR), which can be used to determine probability of myopia, estimate refractive error (RE), and identify and monitor individuals at risk of myopia. The accuracy of these percentile charts was validated using an independent sample of children's eyes. The results showed a high concordance between the estimated and actual measurements.

Summary: This study compared the efficacy of two myopia control contact lenses with a single-vision contact lens. The results showed that the extended depth of focus and MiSight (R) contact lenses demonstrated similar effectiveness in slowing myopia progression. When switched to a single-vision contact lens, myopia progression was similar to age-matched wearers in single-vision contact lenses and did not indicate rebound.

Summary: Globally, one in three people suffer from myopia or short-sightedness. The onset of myopia in children at a young age poses a higher risk of progression and vision-threatening complications. The relationship between sleep and childhood myopia is still not fully understood, with mixed results from various studies. A literature review of 17 studies highlighted the association between sleep duration, quality, timing, efficiency, and myopia in children. However, limitations in methodologies and gaps in knowledge were identified, calling for future research that objectively assesses sleep and myopia, considers diverse samples, and controls for confounding factors.

Summary: Myopia is a complex and evolving field, with ongoing research providing new insights and strategies for myopia control. The International Myopia Institute (IMI) has published white papers and updated evidence, summarizing key findings from the past two years. Studies in animal models have explored the influence of light on eye growth and potential treatments for myopia. In children, the concept of premyopia and early myopia control implementation is gaining attention. Various clinical trials have demonstrated the efficacy and safety of different treatments, such as spectacle lens designs, contact lenses, and pharmaceutical options. The ethics of including control arms in clinical trials and the IMI recommendations for trial protocols are also discussed.
