Scientometric Analysis of Iranian Scientific Productions in the Field of Ophthalmology

Abstract

Background and objectives: Evaluation of scientific productions in different fields using scientometric methods is indispensable for determining scientific trends. The purpose of this study was to perform a scientometric evaluation of Iran's scientific productions in the field of ophthalmology. Methods: We investigated all scientific papers in the field of ophthalmology that have been indexed in the Web of Science from 2000 to the end of 2018. The VOSviewer software (version 1.6.9) was used to draw bibliometric maps considering a threshold of 20 times for the keywords used in this field of medicine. Results: Iran ranked 19th in the world in terms of scientific production on ophthalmology. H-Index of documents written by Iranian authors was 38, with an average citation per item of 7.13. Overall, the documents had received 7262 citations, 6.2% of which were self-citation. We observed that the rate of scientific production has grown dramatically since 2014. Tehran University of Medical Sciences (37.19%) was the most prolific organization in Iran and Seyyed Hassan Ghazizadeh Hashemi (8.63%) was the most prolific Iranian author in this field. All keywords retrieved from the documents on ophthalmology were analyzed, and an ophthalmologist separated the keywords into five clusters. The most frequently used keywords in ophthalmology-related papers belonged to the clusters of Treatment of Retinal Diseases and Glaucoma with 49 appearances. Conclusion: Our results show that the growth of scientific productions in the field of ophthalmology in Iran and its contribution to the global science production is favorable. However, Iranian authors are recommended to pay more attention to selection of appropriate journals for publishing their scientific papers since publishing in prestigious journals with a high impact factor subsequently increases visibility and citation rates.

Scientometric Study of Research in Information Retrieval in Medical Sciences

“…The placement of keywords in clusters and the distance between nodes was based on the simultaneous use of 2 or more similar keywords. The size of each circle in the cluster indicated the abundance of that word in that cluster (14,20).…”

“…While CitNetExplorer is used to analyze a cluster at the level of separate documents, VOSviewer is used to analyze clustering at the entire level of articles. (13)(14)(15)(16)(17).…”

Scientific publications and subject clusters in the field of glaucoma: A scientometric analysis

“…In the field of glaucoma, there are a few studies applying the Scientometric indicators which have been indexed either in the Web of Science (WoS) or PubMed databases. 18 19 20 21 22 23 It seems that Scopus can be a more comprehensive reference for assessment of the research publications in various fields because numerous numbers of journals have been indexed in this database. 24 However, no research has been studied on the scientific publications of glaucoma indexed in the Scopus.…”
