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: 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: This study aimed to compare the agreement between cycloplegic and non-cycloplegic autorefraction and establish a myopia threshold. The results showed that non-cycloplegic refraction underestimates hyperopia and overestimates myopia, but the difference is minimal and not clinically significant for myopic subjects. A threshold of SE <= -0.75 D for defining myopia prevalence using non-cycloplegic refraction is comparable to the standard definition of SE <= -0.50 D for cycloplegic myopic refraction.

Summary: This study aimed to estimate the prevalence, severity, and determinants of refractive errors among school-going children in India. The results showed that myopia, especially, is common in India, with a higher prevalence among older children and variations between different regions, genders, and school types.

Summary: This study analyzed a social visual screening program for school children in Sao Paulo, Brazil, identifying issues such as myopia, hyperopia, and astigmatism, and suggested improvements for the program. The findings were consistent with similar studies, highlighting the importance of diagnosing and providing glasses to underprivileged children. New guidelines, including professional training and community sensitization, are necessary for cost-effectiveness.

Summary: The prevalence and distribution of visual impairment in preschool children in southern China were assessed through a large-scale school-based vision screening program. The study found that 13.1% of the children had visual impairment, mainly caused by uncorrected refractive error, amblyopia, and congenital cataract. The study also found that visual acuity in preschool children improved with age.

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: 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 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 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 aimed to summarize the literature on the prevalence and causes of visual impairment among learners living with hearing impairment in sub-Saharan Africa. The findings indicated a lack of high-quality and well-designed studies in this area, highlighting the need for further research.

Summary: This study aimed to estimate the prevalence of cerebral visual impairment (CVI) related vision problems in mainstream primary school children and to identify potential indicators that might be useful as red flags. They found that CVI-related vision problems were more common than previously thought, with 31.5% of examined children having at least one problem. Assessing at-risk children may help improve outcomes for those with CVI-related vision problems.

Summary: Current research on methods of visual assessment in children with CVI has shifted from focusing solely on visual acuity to exploring other aspects of visual function, such as contrast sensitivity, motion detection, and visual search. Eye tracking has emerged as a promising tool for objective and quantitative visual assessment in both clinical and research settings.

Summary: This study describes the prevalence of visual impairment and glasses ownership among rural and urban migrant Chinese students. The prevalence of visual impairment increases with age, and girls have a higher prevalence than boys. The rate of glasses ownership among students who need them also increases with age, and girls have a higher rate than boys. The unmet need for glasses is highest in junior high school. Per capita gross domestic product and population density are associated with visual impairment and glasses ownership.
