AIM: To analyze the current status, hotspots and trends of studies on the treatments of diabetic retinopathy.

METHODS: Relevant literatures on diabetic retinopathy in Chinese National Knowledge Infrastructure(CNKI)and Web of Science core collection database were retrieved from creation to June 15, 2023, and CiteSpace 6.2.R2 and VOSviewer were used to conduct visualized analysis with the country/issuing institution, research author and keywords.

RESULTS: A total of 5 919 Chinese literatures and 11 475 English literatures were included. The top three countries with global publications are the United States, China and the United Kingdom, respectively. The top three institutions for issuing articles at abroad are Harvard Medical School, Harvard University and Johns Hopkins University, while the top three institutions for issuing articles in China are the Eye Hospital of China Academy of Chinese Medical Science, Hunan University of Chinese Medicine, and Zhongshan Ophthalmic Center of Sun Yat-sen University. The research results of high-frequency keywords in both Chinese and English show that the laser photocoagulation, vitrectomy, traditional Chinese medicine therapy, vascular endothelial growth factor and ranibizumab are research hotspots.

CONCLUSIONS: In recent years, the research hotspots of diabetic retinopathy mainly focus on surgery, vascular protective agents, traditional Chinese medicine therapy, anti-vascular endothelial growth factor, etc., and the research trend mainly focuses on anti-vascular endothelial growth factor drugs.
