目的：探讨2003—2023年热休克蛋白(heat shock proteins,HSP)在眼科领域中的研究进展及前沿趋势。方法：利用Web of Science数据库检索2003年1月—2023年12月26日HSP在眼科领域的文献，采用文献计量学方法、应用VOSviewer及CiteSpaces软件对发文量、国家、机构、期刊、作者、关键词以及学科领域等数据进行定量分析及可视化。结果：共纳入1 079篇HSP在眼科领域的相关文献，总体发文量处于波动状态。美国(n =394)是发文量最多的国家，Investigative Ophthalmology & Visual Science(n =80)是发表相关文献最多的期刊。研究热点主要分为三部分，分别为青光眼发病机制、白内障发病机制及HSP在基因层面的眼科疾病机制研究。研究的前沿主题是青光眼、胆固醇、分子伴侣。生物化学与分子生物学、多学科材料科学和细胞生物学学科领域具有最高的中介中心性值，分别为0.60、0.28和0.26。多学科化学(爆发年份：2017—2023年；强度为6.3)是该领域研究前沿涉及的学科。结论：HSP在眼科领域的研究重点是揭示疾病的遗传背景，探究其在青光眼及白内障中的分子机制以及治疗应用。该领域分子机制研究的进展有赖于多学科的合作。

Objective: To investigate the advances and trends of heat shock proteins (HSP) in ophthalmology published from  2003 to 2023. Methods: The Web of Science database was used to retrieve the literature on heat shock proteins in ophthalmology published from January 1, 2003 to December 26, 2023. Bibliometric methods and VOSviewer and CiteSpaces software were used to analyze and visualize data, including publication count, countries, organizations, journals, authors, keywords and subject categories. Results: A total of 1079 publications related to HSP in ophthalmology were included, and the overall number of publications was fluctuating. The United States (n =394) was the leading contributor among countries. Investigative Ophthalmology & Visual Science (n =80) was the journal with the largest number of publications. The pathogenesis of glaucoma, the pathogenesis of cataract and the mechanism of ophthalmic diseases at the genetic level of HSP were identified as the research hotspots. Glaucoma, cholesterol, and molecular chaperones were identified as frontier research topics. Biochemistry & molecular biology, multidisciplinary materials science, and cell biology have the highest betweenness centrality values of 0.60, 0.28, and 0.26, respectively. Multidisciplinary chemistry (burst years: 2017 to 2023; strength = 6.3) was a subject involved in the research frontier of this field. Conclusion: Research on heat shock proteins in ophthalmology mainly focuses on revealing the genetic background of the diseases and exploring the molecular mechanisms and therapeutic applications in glaucoma and cataracts. The advance in the study on molecular mechanisms in this field depends on multidisciplinary collaboration.

目的：了解近5年世界干眼研究的文献分布特征，并分析这一领域的研究趋势及研究热点。方法：以Web of Science核心数据库(WoSCC)为基础，采用文献计量学方法对干眼相关的全球研究趋势进行评估。通过VOSviewer v.1.6.16构建知识图谱，可视化了该领域的出版物、国家/地区分布、国际合作、作者、来源期刊和研究热点。另外，用CiteSpace IV来捕获爆发的关键词，探索热点的兴起和没落时间，以发现研究前沿。结果：在2016—2020年间共检索到2 567篇同行评议文章，其中美国是发表文献数量最多的国家，文献产量最高的机构是日本的庆应义塾大学。Kazuo Tsubota是该领域发表论文最多的作者，MA Lemp是被引次数最多的作者。Ocular Surface是干眼研究中发表文章最多的杂志。被引用最多的文献主要是TFOS Dr y Eye Workshop II发表的干眼系列报道。关键词聚类分析得出6大类：1)致病机制和病理生理；2)定义和分类；3)流行病学研究；4)治疗；5)继发性干眼；6)诊断。目前的研究前沿是眼痛、瑞巴派特、小切口角膜基质透镜取出术(small incision lenticule extraction，SMILE)手术和泪膜动力学。结论：本研究通过对国际干眼领域近5年的文献进行文献计量学分析，可视化呈现了最近这一领域的研究现状、热点及前沿。干眼研究的前沿主题是眼痛、瑞巴派特、SMILE手术和泪液动力学。

Objective: To understand the literature distribution characteristics of dry eye research in the world in the last 5 years, and to analyze the research trend and hotspots in this field. Methods: Based on the Web of Science Core Collection (WoSCC) database, a bibliometric analysis was conducted to evaluate the global research trends related to dry eye. Knowledge mappings were constructed by VOSviewer v.1.6.16 to visualize the publications, the distribution of countries, international collaborations, author productivity, source journals, and research hotspots in this fifield. In addition, CiteSpace IV was used to capture the keywords of outbreaks and to explore the rise and fall of hotspots. Research frontiers could be discovered by this analysis. Results: In total, 2 567 peer-reviewed articles were retrieved on dry eye research from 2016 to 2020. The United States ranked the highest among countries withthe most publications. The most productive institution was the Keio University. Kazuo Tsubota contributed the largest number of publications in this field, and MA Lemp was the most cited author. Ocular Surface was the most prolific journal in dry eye research. The top-cited references were mainly about the reports of the International Workshop on Meibomian Gland Dysfunction (MGD). The most cited literature was mainly dry eye series reports by TFOS Dry Eye Workshop II. Six categories were obtained by cluster analysis: 1) pathogenic mechanism and pathophysiology; 2) definition and classification; 3) epidemiological study; 4) treatment; 5) secondary dry eye; 6) diagnosis. Current research foreword is ocular pain, rebamipide, small incision lenticule extraction (SMILE) surgery, and tear film dynamics. Conclusion: Through the bibliometrics analysis of the international literature in the field of dry eye in the past five years, this study visualized the current research status, hotspots, and frontier in this field. Leading topics in dry eye research are eye pain, rebamipide, SMILE surgery, and tear dynamics.
