Bibliometric analysis on research of ischemic optic neuropathy from Pubmed database / 中华眼底病杂志

ABSTRACT

Objective To learn the hotspots of study in ischemic optic neuropathy (ION).Methods Literature on ION published in January 2000 to July 2012 was identified in Pubmed database.MeSH terms that frequently appeared were identified and co-word analysis was carried out by cluster analysis.Then a network was drawn using social network analysis.Results A total of 1045 papers were included.The United States,England,Germany,France and Netherlands together accounted for 71.53％ (748) of the articles.There were 28 high-frequency MeSH terms and hot topics clustered into four fields.The appearance frequency of MeSH showed that most research focused on(1)postoperative or arteritic ION;(2) epidemiology,pathology and diagnosis of ION ; (3) pathophysiology and therapy of ION ; (4) chemically induced ION.Conclusion The international main research focus of ION includes four fields,which may provide reference or scholars both in scientific research and clinical research.
