ObjectiveIschemic optic neuropathy (ION) is one of major causes of blindness or severe visual impairment. However, controversies persist regarding its pathogenesis, clinical features and management. This study aimed to conduct a bibliometric analysis to provide an assessment of current status and emerging trends in the field of ION. MethodsPublications spanning from January 2014 to Jun 2024 were retrieved, using the Web of Science Core Collection. Bibliometric and visualized analyses were performed employing the bibliometrix, CiteSpace and VOSviewer. ResultsA total of 776 papers met the inclusion criteria and a fluctuated publication trend was observed. The United States was the leading country. Research topics in ION field encompassed non-arteritic anterior ION (NAION), optical coherence tomography angiography, neuroprotection, optical coherence tomography, spine surgery, giant cell arteritis (GCA), optic disc diameter, peripapillary hyperreflective ovoid mass-like structures, vaccination, and branch retinal vein occlusion, based on the co-citation references analysis. The keywords “COVID-19”, “oxidative stress”, “inflammation” and “optic neuritis” experienced burst lasting until 2024. ConclusionDuring the past decade, advancements in in vivo imaging techniques are continually enhancing our understanding of the pathogenesis of ION and facilitating accurate diagnosis. NAION has been a prominent research topic, covering its pathogenesis, clinical features, and management. Studies on arteritic ION and GCA have garnered widespread attention, especially due to advances in treatments. Future research is warranted to identify standardized therapies for non-arteritic ION, potentially incorporating neuroprotective agents, and to formulate steroid-sparing treatment strategies aimed at preventing vision loss in arteritic ION, rather than merely addressing GCA.
