Summary: This population-based study investigated the refractive status and prevalence of refractive error in Chinese preschool children aged 1-6 years old. The study found that the prevalence of myopia decreased with age in preschool children younger than 5 years old and then slightly increased at 5-6 years, potentially indicating early signs of myopia in school-age children. The research highlights the need for greater attention to be given to children in this age group.

Summary: This study aimed to investigate the prevalence of myopia and hyperopia in individuals aged 60 years and above. A multi-stage stratified random cluster sampling method was used to select participants, who underwent optometric examinations. The results showed that the prevalence of myopia and hyperopia was 31.65% and 45.36%, respectively. Multiple logistic regression analysis revealed that age, history of glaucoma surgery, pseudophakia, axial length, and mean keratometry were significantly associated with myopia prevalence, while education level was inversely related. History of glaucoma surgery, pseudophakia, axial length, and mean keratometry were inversely associated with hyperopia prevalence. A significant proportion of myopic and hyperopic patients still had incomplete visual acuity after refractive error correction.

Summary: The purpose of this study was to determine the prevalence of refractive errors in a group of 8-year-old school children in northwestern Poland. The results showed that mild hyperopia was the most common refractive error (37.6%), followed by myopia (16.8%) and astigmatism (10.6%). Girls were more likely to have mild hyperopia (p = 0.0144) and were significantly more likely to wear glasses (p = 0.00093).

Summary: This study investigated the prevalence of refractive errors in school children in urban and rural settings in Dalian, China. The results showed that urban students had higher rates of myopia and anisometropia, but lower rates of hyperopia compared to their rural counterparts. These differences in refractive errors were attributed to social-demographic and physiologic factors.

Summary: The study aimed to assess visual acuity in 5-year-old children using LEA charts and found a high frequency rate of reduced visual acuity in this age group. Amblyopia and uncorrected refractive errors were identified as the main causes of reduced VA in childhood, negatively impacting child development, especially at the educational level.

Summary: The prevalence of reduced visual acuity among children aged 6-15 in Yuhua District has increased over time, with a marked increase observed between 2002 and 2018. The epidemic of reduced visual acuity started earlier in 2018 compared to 2002, suggesting that interventions should be initiated before the age of 9.

Summary: The study found that customized progressive addition lenses have a minimal protective effect against the progression of myopia in children with esophoric myopia, compared to single vision lenses. Regulating near heterophoria and accommodative lag by near addition lenses may not be an effective method to prevent myopia progression.

Summary: This study investigated the influence of prolonged periods of near work on accommodative response, accommodative microfluctuations (AMFs), and pupil diameter in juvenile myopic and emmetropic individuals. The study found that myopic individuals exhibited an unstable tendency in their accommodation system during prolonged near work at a certain time point. Accommodative microfluctuations may serve as a sensitive and objective indicator of fatigue in juvenile myopes under sustained near work.

Summary: In this study, we investigated how ocular accommodative responses and pupil diameters change under different light intensities. We found that light intensity significantly affects accommodation and pupil diameter, with larger changes observed under dynamic lighting compared to static lighting. These findings suggest that light intensity plays an important role in effective accommodation function training.

Summary: This study evaluated the frequency and associated factors of clinically significant axial length shortening among myopic children following repeated low-level red light therapy. The findings showed that more than a quarter of children had axial length shortening > 0.05 mm following the therapy, with an overall mean axial length change of -0.142 mm/year. Further studies are needed to explore the underlying mechanisms of axial length shortening.

Summary: The purpose of this study is to distinguish the effects of age and grade on the development of myopia. The data of Grade 1 and Grade 2 students in 2018 and 2019 were examined, and regression analysis and regression discontinuity analysis were used to assess the development of refraction. The results indicate that grade increase has a more significant impact on the myopic shift than age.

Summary: This study developed and validated models to predict the development of myopia based on cycloplegic refraction or ocular biometry. The study identified thresholds of premyopia and found that cycloplegic refraction at baseline is a better predictor of myopia onset compared to other ocular biometric measurements. The findings suggest that premyopia can be successfully defined and used to predict the need for more aggressive myopia prophylaxis.

Summary: This study assessed the longitudinal changes in the crystalline lens in persistent non-myopic and myopic children. The results showed a three-stage pattern of change in lens thickness in children ages 3 to 15 years, with a rapid decrease from 3 to 7 years, a slower decrease from 7 to 11 years, followed by an increase thereafter. Lens power consistently decreased in all cohorts during the follow-up period.

Summary: The study found that using uncorrected visual acuity alone for myopia screening had poorer accuracy, while the combined use of uncorrected visual acuity and noncycloplegic refraction tests, as well as the combined use of axial length/corneal curvature radius and noncycloplegic refraction tests, achieved optimal accuracy for myopia screening. Setting age-specific cutoffs can increase accuracy, and the prevalence obtained from primary screening should be corrected according to the data of cycloplegic refraction after referral.
