Summary: A study in rural northern India found a 6.4% prevalence of myopia in children, with a strong inverse association with time spent outdoors especially in private schools. Awareness of modifiable risk factors, regular screenings, and lifestyle modifications are essential for addressing the increasing prevalence of myopia in rural areas.

Summary: The prevalence of myopia in African school children is increasing, with an overall rate of 4.7%. The prevalence is slightly higher in females and older children (12-18 years) but the differences are not significant. The use of cycloplegic refraction is associated with a significantly lower prevalence of myopia compared to non-cycloplegic refraction.

Summary: The study aims to determine the distribution and causes of vision impairment (VI) and blindness among patients at Nigerian Army Eye Centre Lagos, Nigeria. The major causes of VI and blindness were cataracts, glaucoma, and uncorrected refractive error (URE). Males were more affected by VI, but there was no significant difference between males and females. The prevalence of VI was higher in the age group of 60 years and above. Early screening and management for cataracts, URE, and glaucoma are highly recommended.

Summary: The study aimed to determine the prevalence of refractive errors and causes of visual impairment in school children in Enugu State, South-eastern Nigeria. The results showed a low prevalence of refractive error in the study population, with myopia being more common. Despite the low prevalence, school vision screening is still important for African children to identify other ocular morbidities.

Summary: This study investigated visual impairment, refractive errors, and barriers to eye care among the homeless population in Cardiff, UK. Findings show a significant disparity in ocular health, visual acuity, and refractive error compared to the general population. 50% of homeless participants had not received optometric care in the last 5 years.

Summary: The study examined the prevalence of visual impairment and associated factors among secondary school students in Nampula province, Mozambique, revealing relatively high rates of refractive error and visual impairment. The findings suggest the need for greater intervention and management at the school level to address these issues effectively.

Summary: This study aimed to determine the prevalence of myopia at the community level. A population-based, cross-sectional study was conducted in Delhi to screen the visual acuity of 20,000 children aged 0-15 years. The results showed a prevalence of 3.7% myopia, with 45% of cases being uncorrected.

Summary: This study used focus group discussions to analyze the reasons for parental non-adherence to eye exam referrals in Cross River State, Nigeria. The study found that modifiable barriers such as disbelief in vision problems, issues with referral letters, and contextual factors like poverty and logistics influenced parents' adherence behavior. Recommendations were made to educate the public on the importance of child eye care and correct parents' misconceptions.

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: The process of learning begins in childhood and accurate vision can greatly affect a child's learning capacity. This research aimed to study the impact of refractive corrections on the academic performance of high school children in Lahore. The results showed a significant improvement in academic scores after refractive corrections.

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: Predicting the need for cycloplegic assessment and the refractive state under cycloplegia in school-age children based on non-cycloplegic ocular parameters. A machine learning model was established to effectively predict the refractive status of school-age children. This study provides a theoretical basis and supporting evidence for epidemiological research on myopia and accurate analysis of vision screening data.

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: The study aimed to report the prevalence of refractive error among school students in the east district of Sikkim, India. The findings showed that myopia was the most common error, with a higher prevalence among 14-17-year-old children and slightly higher in females than males, while the highest prevalence of refractive error was found among the most backward classes.

Summary: The Lhasa Childhood Eye Study is the first school-based cohort study to reveal the prevalence and pattern of refractive error and visual impairment in Lhasa. Effective strategies such as corrective spectacles should be considered to alleviate treatable visual impairment.
