Bibliometric analysis of pediatric glaucoma

PURPOSE: The research activity in pediatric glaucoma (PG) was qualitatively and quantitatively evaluated using a scientometric approach. METHODS: The “Web of Science” database was accessed for primary bibliometric data regarding PG using search terms “pediatric glaucoma,” “paediatric glaucoma,” “congenital glaucoma,” and “childhood glaucoma.” The data was analyzed for total research productivity, citations, and scientific output in terms of journals, countries, institutions, and authors. The results were further characterized for coauthorship links and visualized by VOS viewer software. Also, the top 25 cited articles were reviewed with the above bibliometric characteristics. RESULTS: One thousand two hundred and sixty-nine items were obtained from our search query from 1955 to 2022; these received 15,485 citations, originated from 78 countries. The top-3 contributing countries were the United States of America (n = 369), India (n = 134), and China (n = 127). LV Prasad Eye Institute (n = 58), Duke University (n = 44), and King Khalid Eye Specialist Hospital (n = 42) were the top-3 productive institutes. The top-3 prolific authors were Mandal AK (n = 53), Freedman, SF (n = 36), and Sarfarazi, M (n = 33). Journal wise, “Investigative Ophthalmology” (n = 187), “Journal of Glaucoma” (n = 92), and “Journal of AAPOS” (n = 68) were the journals in which the most articles were published. The top-25 cited documents received 3564 citations and were published between 1977 and 2016. The key areas of interest were basic sciences (genetics of childhood glaucoma) and surgical management. CONCLUSION: United States of America, LVPEI, Mandal AK, and “Investigative Ophthalmology” were the top rankers as far as the productivity and publications related to PG are concerned. Articles on molecular genetics in PG have received interest among the ophthalmology community.
