Abstract

PURPOSE

Characterize geographical trends in ophthalmology research between 2002 and 2022 and explore associations among study locations, designs, and funding sources

DESIGN

Trend study.

METHODS

Analysis of 4199 publications from the American Journal of Ophthalmology, British Journal of Ophthalmology, Investigative Ophthalmology & Visual Science, JAMA Ophthalmology, and Ophthalmology. All original full-length publications from 2002, 2012, and 2022 were included. Exclusion criteria were meta-analyses, literature reviews, and case reports. Main outcome measures were publication years, locations, study designs, and funding sources.

RESULTS

Publications from North America (45.8%), Europe (30.7%), and Asia (28.9%) were the most common, whereas Africa (0.8%) and South America (1.4%) were least represented. North American research decreased by 10.6% (P < .001), whereas Asian research increased by 25.4% (P < .001). The United States contributed 42.3% of research but experienced an 11.3% decline from 2002 to 2022 (P < .001). Publications in the United States received 5.8% more industry funding from 2002 to 2022 (P = .006). China's research grew by 17.0% and had the highest proportion of government (83.1%) or intramural (24.2%) funding (P < .001), with government-funded studies increasing by 46.7% (P < .001). Japan was less associated with all funding types (P ≤ .001). Singapore, Iceland, and Switzerland were top performers when adjusted for population size.

CONCLUSIONS

Within the examined journals, the United States remains the primary research contributor, with China witnessing rapid growth and Japan facing stagnation. Despite the declining research proportion in the United States, North America and Europe continue to maintain a disproportionately high presence in prestigious academic journals. Publications from Africa and South America are limited.

2002-2022 年全球眼科研究的地域趋势。

目的：描述 2002-2022 年间眼科研究的地域趋势，探讨研究地点、设计和资金来源之间的关联设计：趋势研究方法：分析《美国眼科杂志》、《英国眼科杂志》、《眼科学与视觉科学调查》、《美国医学会杂志眼科》和《眼科学》中的 4199 篇论文。收录了 2002 年、2012 年和 2022 年发表的所有原始长篇论文。排除标准为荟萃分析、文献综述和病例报告。主要结果指标为发表年份、地点、研究设计和资金来源：来自北美（45.8%）、欧洲（30.7%）和亚洲（28.9%）的论文最多，而非洲（0.8%）和南美（1.4%）的论文最少。北美的研究减少了 10.6%（p < 0.001），而亚洲的研究增加了 25.4%（p < 0.001）。美国贡献了 42.3% 的研究成果，但 2002-2022 年间下降了 11.3% （p < 0.001）。2002-2022 年间，美国出版物获得的行业资助增加了 5.8%（p = 0.006）。中国的研究增长了 17.0%，政府（83.1%）或校内（24.2%）资助的比例最高（p < 0.001），政府资助的研究增长了 46.7%（p < 0.001）。日本与所有资助类型的关联度较低（p ≤ 0.001）。根据人口规模进行调整后，新加坡、冰岛和瑞士的表现最佳：在所研究的期刊中，美国仍是主要的研究贡献者，中国的研究贡献率快速增长，而日本则停滞不前。尽管美国的研究比例在下降，但北美和欧洲在著名学术期刊中的比例仍然过高。非洲和南美洲的论文数量有限。

期刊介绍： The American Journal of Ophthalmology is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished manuscripts directed to ophthalmologists and visual science specialists describing clinical investigations, clinical observations, and clinically relevant laboratory investigations. Published monthly since 1884, the full text of the American Journal of Ophthalmology and supplementary material are also presented online at www.AJO.com and on ScienceDirect. The American Journal of Ophthalmology publishes Full-Length Articles, Perspectives, Editorials, Correspondences, Books Reports and Announcements. Brief Reports and Case Reports are no longer published. We recommend submitting Brief Reports and Case Reports to our companion publication, the American Journal of Ophthalmology Case Reports. Manuscripts are accepted with the understanding that they have not been and will not be published elsewhere substantially in any format, and that there are no ethical problems with the content or data collection. Authors may be requested to produce the data upon which the manuscript is based and to answer expeditiously any questions about the manuscript or its authors.
