AIM: To explore the global trends and focus of glaucoma research from 2009 to 2018. METHODS: Searching for glaucoma-related articles published in Science Citation Index Expanded (SCIE) database during 2009-2018, and describing the distribution of the published year, countries, authors, institutions, funding agencies, journals, impact factor, citation and hot research topic of articles by using bibliometric methods. Meanwhile, we compared some of these indicators over two five-year periods, from 2009 to 2013 and from 2014 to 2018. RESULTS: A total of 19 609 glaucoma-related articles were retrieved and the global SCIE articles have increased yearly from 2009 to 2018. The USA was the pioneer which has made great contributions. China kept the second place and the number of publications has increased rapidly between 2014 and 2018. The author with the highest number of publications was Weinreb, RN. Co-occurrence maps were built amongst the top 50 authors or the top 50 institutions with the most articles, which visualize the closer collaboration of international authors or institutions. The journal has published the most papers. Glaucoma literature with an impact factor of 3-5 points accounted for the largest proportion (28.96%). The most frequently cited paper had 798 citations. The top three hot areas on glaucoma were intraocular pressure, optical coherence tomography (OCT) and retinal ganglion cells. And trabecular meshwork, primary angle-closure glaucoma and Spectral-domain OCT have become new hot research topics in recent five years during 2014-2018. CONCLUSION: Bibliometric analysis is an effective method to describe the global literature on glaucoma. In a 10-year literature survey from 2009 to 2018, global glaucoma research has developed in a balanced manner, and the cooperation between various institutions and teams has become closer. Glaucoma-related pathogenesis research, imaging examinations of OCT and surgery therapy have attracted most attention.
