Abstract

Objectives: In this study, we aimed to review the scientific literature on Diabetic retinopathy (DR).

Materials and methods: Scopus bibliometric database was searched in English. Original research articles made between 1941-2021 containing the keywords "diabetic", "DM" and "retinopathy" and "article" in the title, abstract, and keywords were found. Publications were evaluated in terms of the institution, author, publication year, subject, number of citations, and the journal in which they were published.

Results: It was determined that there were 58,516 publications on DR, and the first publication was published in 1941. 41,996 of them were research papers. Only research articles were evaluated in our study. It was determined that there was an increase in the number of articles after the 1960s and that the year 2020 was the year in which the highest number of articles were published (6.3%). The United States (21.9%) and China (10.6%) were the countries with the highest number of articles. Turkey ranked 13th. The journals in which the highest number of articles were published were Investigative Ophthalmology and Visual Science (3.1%) and Ophthalmology (1.9%). The third leading institution with the most articles; Harvard Medical School (1.4%), University of Melbourne (1.1%), and Wilmer Eye Institute (1%).

Conclusion: The increase in scientific research on DR, both on treatment and prevention, causes an increase in the number of publications. The ranking of our country should be raised to higher levels in this regard.
