Scientometric analysis and mapping of 20 years of glaucoma research.

AIM
To provide a scientometric analysis in the field of glaucoma.


METHODS
A bibliometric method was used to obtain a view of the scientific production in field of glaucoma by data extracted from the Institute for Scientific Information (ISI) from 1993 to 2013. Specific parameters were retrieved from the ISI. Articles about glaucoma were analyzed regarding the topics' structure, history, and document relationships using HistCite software. Also, the trends in the most influential publications and authors were analyzed.


RESULTS
The number of articles was constantly increasing, and most highly cited articles addressed clinical and epidemiologic topics in this field. During the past three years, there has been a trend towards genomic research studies and also more molecular translational research.


CONCLUSION
This was the first scientometric report on glaucoma, analyzing the characteristics of papers and the trends in scientific production. A constant increase was observed in the number of papers, while the subject of papers had a shift in the past three years towards genomic research studies.
