ABSTRACT
Objective@#To explore the international development trends and research hotspots of outdoor activities affecting the progression of children’s myopia, and to provide a reference for researching on effective ways to prevent children’s myopia.@*Methods@#Totally 291 relevant documents included in the "Web of Science" core set database were used as research objects, and CiteSpace software was used for visual analysis.@*Results@#At present, the publications in this field were mainly in the United States(81), China(80), Australia(76), and Singapore(33); the top three research institutions were "Natl Univ Singapore"(29), "Australian Natl Univ"(27), "Capital Med Univ"(25); the main authors were "Saw SM", "Morgan IG", "Mitchell P". The field has been developed on the basis of "Ophthalmology", "Public, Environmental and Occupational Health", and has been integrated into 32 disciplines. The research content included "exploration of high risk factors for the progression of children’s myopia" and "outdoor activities", "intervention in children’s progression of myopia" and "longitudinal tracking of children’s vision development". Randomized clinical trials that longitudinally track the correlation between changes in eyeballs and the progression of myopia and the effects of outdoor activities on the biological characteristics of children’s eyeballs have become a hot topic in this field.@*Conclusion@#Research on the effects of outdoor activities on the progression of myopia in children has increased dramatically. The study of increasing outdoor activities to interfere with the progression of myopia in children and the vertical tracking of key factors affecting the biological characteristics of children’s eyeballs have become the current international trends.
