Abstract

Objective

To study the distribution of the literature and the trend of international research of proliferative vitreoretinopathy (PVR) in 10 years from 2009 to 2018.

Methods

Using Web of Science database of the American Institute of Scientific Information as the data source to collect literature on proliferative vitreoretinopathy published from 2009 to 2018 and a statistical analysis on the distribution of the publication time, nation and funding agency was made to figure out the institution, periodical, author with highest citations respectively among the collected literature.Meanwhile, the bibliometric analysis software Citespace and VOSviewer were employed to carry out the distribution analysis and cluster analysis of keywords as well as the co-citation cluster analysis.

Results

A total of 905 articles related to PVR were included, mainly in English, most of which were written by American authors, and the number of literature published by Chinese authors was ranked the second.Among all the article funding institutions, the National Natural Science Foundation of China ranked NO.1 with the most funded articles.Citations increased year by year since 2009 and increased obviously since 2013.The journal with the highest citations was Investigative Ophthalmology & Visual Science, and the research institution with the highest citations was Harvard University.The statistical analysis of the citation quantity also showed that the top five authors with the highest citations were all from Massachusetts Eye and Ear, Department of Ophthalmology, Harvard Medical School.The results of cluster analysis showed that there were 41 high-frequency subject terms, and they were mainly grouped in 4 categories, which were etiology, risk factors, molecular mechanism, treatment and management of PVR.Keywords network visualization and overlay visualization both showed that etiology and risk factors were the focus of current research, while epithelial mesenchymal transition, transforming growth factor-β and fibrosis were new research fields in recent years.The results of citation cluster analysis showed there were 12 co-citation clusters.

Conclusions

The literature of PVR shows an upward trend, and the researches focus on the molecular mechanism, prevention, and neuroprotection of PVR, which may be the future PVR research direction.
