国际同行评审的出版物构成了循证医学的基础，也是眼科研究活动的主要指标之一。本文从地理位置、人口统计和经济研究概况等方面考察了这类文章的起源。使用Medline/Pubmed搜索引擎分析了5年来来自5种眼科杂志的论文。原籍国是根据相应提交人的地址确定的。分析了全球眼科研究产出与人口统计和研究支出的关系。从2002年到2006年，总共分析了来自67个国家的7754篇文章。在此期间，发表的文章总数增加了29%以上。美国(US)的文章数量最多。新加坡每10(6)人口出版的出版物最多。国内生产总值(GDP)超过20,000美元与人口调整后的产出之间存在关系。美国、英国和日本是最大的总贡献者。经人口调整后的数据显示，新加坡、冰岛和澳大利亚是最多产的国家。GDP与排名最靠前的人口调整国家之间存在关系。人口调整后生产率最高的10个国家在研发方面的支出相对高于总贡献率最高的10个国家。
International peer-reviewed publications form the basis of evidence-based medicine and are one of the main indicators of ophthalmology research activity. This paper examines the origins of such articles in relation to geographical location, population demographics and economic research profiles. Publications from five ophthalmology journals over 5 years were analysed using the Medline/Pubmed search engine. Country of origin was ascertained based on the address of the corresponding author. Worldwide ophthalmology research output was analysed in relation to population demographics and research expenditure. In total, 7,754 articles from 67 countries from 2002 to 2006 were analysed. The overall number of articles published increased by over 29% during this period. The United States (US) produced the greatest number of articles. Singapore produced the most publications per 10(6) population. There was a relationship between gross domestic product (GDP) greater than $20,000 and population-adjusted output. The US followed by the United Kingdom and Japan were the greatest gross contributors. Population-adjusted figures revealed that Singapore, Iceland and Australia were the most prolific nations. There was a relationship between GDP and the top-ranked population-adjusted countries. The top 10 most productive population-adjusted countries spend relatively more on research and development than the top 10 gross contributors.
