Research Atlas Analysis on the Application of Huoxue Lishui Method (Promoting Blood Circulation and Diuresis) in Ophthalmology Based on VOSviewer’s and CiteSpace’s Methods

Abstract

Objective: The objective of this study was to summarize the research context, hotspots, and the development trend of Huoxue lishui method in ophthalmology in the past decade by reviewing the relevant publications. Materials and Methods: Relevant publications on the application of Huoxue lishui method in ophthalmology from January 1, 2011, to December 31, 2021, in databases such as CNKI, VIP, and Wanfang were retrieved. The analysis of coauthorship, keyword co-occurrence, keyword clustering, keyword emergence, and keyword timeline map of the publications was done with bibliometrics tools CiteSpace and VOSviewer. Results: A total of 100 publications were included in the analysis. The year 2020 saw the publication of most papers concerning the application of Huoxue lishui method in ophthalmology. High-frequency words are macular edema, Huoxue lishui, diabetic macular edema, Huoxue lishui method, Huoxue lishui formula, and promoting Qi and nourishing Yin. Three research hotspots were identified through keyword clustering analysis. Keyword emergence analysis and keyword timeline map indicated that a combined treatment of Huoxue lishui method and promoting Qi and nourishing Yin and diabetic ophthalmology is predicted to be research frontiers. Conclusions: Through the use of knowledge maps, this article reveals the research status in this field in the past decade and highlights the major directions, research hotspots, and development trends, providing references for further research in this field.
