Abstract
PURPOSE: To characterize the global patterns and map previous and emerging trends in ophthalmic imaging technology for glaucoma diagnosis through bibliometric analysis. METHODS: This cross-sectional study examined ophthalmic imaging technology for glaucoma diagnosis research evolution and theme trends from 2015 to 2024, using bibliometric analysis of Web of Science Core Collection data. RESULTS: From 2015 to 2024, a total of 8192 articles were published. There has been a significant surge in research interest in ocular imaging technology for glaucoma diagnosis over the past decade. The Journal of Glaucoma published the most manuscripts (674 publications), and Investigative Ophthalmology and Visual Science produced the highest citations (13,950 citations). The United States (2404 publications and 49,729 citations), the University of California System (569 publications, 13,147 citations), and Weinreb, Robert N. (226 publications, 7083 citations) were the most productive and impactful country, institution, and author, respectively. The co-occurrence cluster analysis of the top 100 keywords forms eight clusters: (1) advanced computational techniques, (2) anterior segment imaging, (3) imaging applications, (4) neuroprotection and retinal research in glaucoma, (5) optical coherence tomography and structural analysis, (6) vascular and choroidal analysis in glaucoma, (7) accuracy of medical imaging diagnostic tests, and (8) visual field assessment and disease progression. Further discussions into the subtopics were provided to assist researchers to determine the range of research topics and plan research direction. CONCLUSIONS: Publications and citations on research related to ocular imaging technology for glaucoma diagnosis have increased over the past decade. The study illuminates the trends, global collaboration, fundamental knowledge, research hotspots, and emerging frontiers in this field.
