ObjectiveTo summarize the research status, hotspots, and development trends of ocular toxocariasis (OT) from 1993 to 2024. MethodsThe literature related to OT included in the Web of Science Core Collection dataset from 1993 to 2024 was retrieved and screened. The bibliometric softwares, VOSviewer and CiteSpace were applied to visually analyze the annual publication volume, countries, institutions, core authors, journal distribution, co-cited references, and keyword clustering. ResultsA total of 279 articles were included. There was an overall fluctuating upward trend of annual publications from 1993 to 2024, with the highest number of publications in 2020 (24 articles, accounting for 8.60%). There was an increasing trend in the frequency of citations to relevant literature. Authors from the United States had the highest number of publications (50 articles, 17.92%). Among institutions, Tokyo Medical and Dental University had the most published articles (11 articles, 3.94%). Among authors, professor Ding Xiaoyan from Zhongshan Eye Center at Sun Yat-sen University is the author with the most published papers (6 articles, 2.15%). Among journals, Ocul Immunol Inflamm had the highest number of published articles (21 articles, 7.53%). Highly cited references showed a significant clustering tendency, which were epidemiology, clinical characteristics and treatment, and immunological diagnosis. Keyword co-occurrence analysis showed that clinical features, serological diagnosis, epidemiology, immunodiagnosis, granuloma and treatment were high-frequency keywords. Timeline view map showed that the 9 clusters could be divided into 3 categories: epidemiological investigation including risk factors and seroprevalence (#0), clinical research including clinical features and treatment modalities (#1, #2, #3, # 6, #7), immunological detection and laboratory examination (#3, #5, #8). The keywords bursts analysis showed that the trend of research hot topics of OT had shifted from the initial study of animal experiments and immunological detection to the subsequent study of risk factor, and then to clinical characteristics studies combined with multimodal imaging technology. ConclusionsOver the past three decades, the number of publications on OT research has shown an increasing trend and the research hotspots have mainly focused on epidemiology, immunological detection and clinical features. The multimodal imaging diagnosis technology based on clinical features and the treatment strategy based on pathogenesis remain crucial directions for future research.
