Global research trends of myopia in children and adolescents: A bibliometric review with hotspot visualization
Xiao-Lei Yin, Shu-Xing Ji, Xiu-Xin LiBackground:
The rapidly rising global prevalence of childhood myopia has become a major public health concern, accompanied by a continuous annual increase in relevant academic publications. Against this backdrop, this study adopted bibliometric methods to analyze the research hotspots and evolutionary trends in this field.
Methods:
Publications related to myopia in children and adolescents were collected from the Science Citation Index Expanded of the Web of Science Core Collection database. A bibliometric and visualization analysis was performed using Microsoft Office Excel and VOSviewer to identify the most influential countries, papers, and authors and to construct the visualization map of citation, co-citation, and co-occurrence.
Results:
After screening, 3413 papers met the inclusion criteria. China had the largest number of published papers, whereas the United States enjoyed the highest citations. Moreover, cooperation network analysis showed close cooperation among China, the United States, and Australia. The review “Myopia” in 2012 was the most-cited article. Among the 10 most-cited articles, outdoor time and the development of myopia in children were the topics with the highest frequency. As an expert in the field of epidemiology of myopia research, Saw SM contributed the most citations. The burst keywords were divided into 3 clusters through co-occurrence analysis: epidemiology, management, and mechanism of myopia in children and adolescents.
Conclusion:
This bibliometric analysis of myopia in children and adolescents helps researchers identify hotspots and research frontiers in the field and might provide a direction that future research should concentrate on.
