Trends in Authorship of Original Scientific Articles in Journal of Glaucoma: An Analysis of 25 Years Since the Initiation of the Journal.

PReCIS:: Publications in glaucoma have seen an increase in the number of authors and disclosures per article, authors with dual degrees, and international authors, but contributions of women to articles published remains low. PURPOSE: Authorship trends have been studied across many medical specialties and in ophthalmology as a whole, but not specifically in glaucoma. We explored the authorship trends of original scientific articles in the Journal of Glaucoma. METHODS: We recorded the number of authors and disclosures per article, degree type of first and last authors, geographical origin of corresponding author, and gender of first and last authors of original content from the Journal of Glaucoma published in 1992, 1997, 2002, 2007, 2012, and 2017. RESULTS: A total of 642 articles were analyzed. From 1992 to 2017, annual published articles increased from 38 to 242 (P=0.02), the mean number of authors per article increased from 3.2 to 5.2 (P 0.28). CONCLUSIONS: Consistent with authorship trends across various other medical specialties, glaucoma has seen an increase in the number of authors and disclosures per article, authors with dual degrees, and authors from the "Far East" and "Other" regions. However, contributions of women to articles published in Journal of Glaucoma remains low.
