Abstract:
AIM: To analyze the current status, research hotspots, and development trends of international studies on ocular surface microbiota based on bibliometrics.METHODS: Leveraging the Web of Science database, we conducted a targeted literature search on ocular surface flora. The retrieved data were meticulously screened and weighted to enhance relevance. The bibliometric analysis delved into publication trends, authorship patterns, institutional collaborations, and pivotal research themes. Employing Cite Space software, we visually dissected the landscape of institutional and national partnerships, citation impact, keyword co-occurrences, keyword clustering dynamics, and the emergence of new research trends.RESULTS: A total of 3 884 publications were ultimately included, with an overall upward trend in the number of publications in the field of ocular surface microbiota from 2003 to 2023, with the most rapid growth occurring from 2019 to 2022. The top three regions/countries by publication volume are the United States(1 039 papers), China(570 papers), and India(302 papers). The top three authors by publication volume are Willcox Mark(48 papers), Sharma Savitri(33 papers), and Fleiszig Suzanne M.J(27 papers). The top three institutions by publication volume, all from the United States, are the University of California, L.V. Prasad Eye Institute, and Harvard University. The citation network map of the literature includes 801 nodes and 1 508 connections, with the most frequently cited document being Temporal Stability and Composition of the Ocular Surface Microbiome. The top 5 keywords by frequency of occurrence are, in order, keratitis, bacterial flora, identification, inflammation, and endophthalmitis. The keyword clustering analysis yielded a total of 8 clusters, which are specifically reflected in three aspects: ocular-related diseases, the relationship between ocular surface microbiota and ocular surface structures, and detection methods for ocular surface microbiota. The keyword with the highest burst strength is ciprofloxacin. Keywords that have emerged in recent years and continue to the present include diversity, gut microbiome, and ocular surface microbiome.CONCLUSION: Currently, the study of ocular surface microflora is gaining momentum globally, with a particular focus on the diversity of microflora, the composition of the core microbiome, and its impact on ocular diseases. In the future, research should concentrate on elucidating the functional metabolism of the ocular surface microflora and further investigate the causality and mechanisms by which changes in the ocular surface microflora are related to diseases.
