Objective To describe the current status of visual disorders among children aged 3-6 years in the study area, so as to provide reference for the prevention and control of eye diseases and visual disorders in children. Methods The study was carried out based on the vision screening project of a county in Shandong province in 2021, and the data included children′s demographic information, kindergarten characteristics, and vision screening results. Visual disorders included poor visual acuity, myopia, and suspected insufficient hyperopia reserve. The prevalences of visual disorders were described and age-related trends were examined by the trend chi-square test. Results This study included a total of 14,198 children aged 3-6 years old. Among the 14,198 subjects, the prevalences of poor visual acuity, myopia, suspected insufficient hyperopia reserve were 19.6%, 3.1%, 42.5%, respectively. The prevalences of poor visual acuity in children aged 3, 4, 5 and 6 years were 9.4%, 16.4%, 24.5% and 22.8%, and the prevalences of myopia were 1.9%, 1.3%, 3.6% and 9.0%, respectively, both of which showed an increasing trend with age. The prevalences of suspected insufficient hyperopia reserve were 54.6%, 42.3%, 39.2% and 46.0%, respectively, which had no increasing trend with age. The differences of the three measurements between male and female children were less than 2.0 percentage points. The prevalence of poor visual acuity in rural children was 8.9 percentage points higher than that in urban children, the prevalence of myopia was 5.3 percentage points higher, and the prevalence of suspected insufficient hyperopia reserve was 9.6 percentage points higher. In urban area, the prevalence of poor visual acuity in private kindergartens was 9.1 percentage points higher than that in public kindergartens, and the prevalence of suspected insufficient hyperopia reserve was 17.3 percentage points higher. However, in rural area, the prevalence of myopia in private kindergartens was 2.4 percentage points lower than that in public kindergartens and the prevalence of suspected insufficient hyperopia reserve was 8.0 percentage points lower. Conclusion In the study area, the prevalences of poor visual acuity, myopia, suspected insufficient hyperopia reserve in children aged 3-6 were close to 20%, slightly higher than 3% and more than 40%, respectively. The prevalence of poor visual acuity and myopia increased with age, but the prevalence of suspected insufficient hyperopia reserve didn′t show increasing trend with age. There were obvious differences in visual disorders between children in the urban area and rural area, so it is advisable to explore the potential causes of the difference to improve prevention and control of eye diseases.
