Abstract:
Background The research field of optic neuritis has developed rapidly and become more complex in recent years.It is very important for the reseachers and clinicians to known its status and the future trend.Objective This survey was to learn the distribution pattern,subject domain knowledge and worldwide research tendency of optic neuritis based on literatures in PubMed database.Methods Literatures on optic neuritis published in January 2000 to July 2012 were identified in PubMed database.The analytic dimention of an article included journal,published year,author,country and language.After core Mesh terms had been characterised by bibliographic item co-occurrence mining system (BICOMS),the co-occurrence matrix was built.Cluster analysis and multiple diamensional analysis were finished by SPSS 17.0.Then visualized network was drawn using ucinet 6.0.Results Totally 2 191 literatures were included,the number of articles increased from 105 in 2000 to 282 in 2011.The United States,England,Germany,Netherlands and Japan together accounted for 73.71％ of articles.There were 52 high-frequency subjects and hot topics were clustered into 9 categories.The visualized domain knowledge map was successfully built.The immunologic research was fully developed.The topic on etiology and diagnostic research,pathologic research,physiologic research and neuromyelitis optica (NMO) research had become core domain,while the studies of medication therapy,non-central nervous system idiopathetic demyelinating optic neuritis,epidemiology and genetics were not developed well.Conclusions Global optic neuritis publications display a continuous growth in the new millennium.The Big 5 in scientific literature on optic neuritis are the United States,England,Germany,Netherlands and Japan.The international main research focus includes 9 fields,which may provide reference or scholars both in scientific research and clinical research.
