Publication trends in pars plana vitrectomy in the last decade

Abstract

Purpose: The aim of this study was to demonstrate the publication trends in the area of pars plana vitrectomy (PPV) in the last ten years. Materials and Methods: All of the PPV related research articles, case reports, letters, reviews and meeting abstracts published between January 2009 and December 2018 indexed on the Web of Science Core Collection were evaluated. A bibliometric filter was used to capture publications about PPV by using the key words 'pars plana vitrectomy', 'retina surgery' and 'vitreous surgery' in the 'topic' selection mode. Publication years, topics, document types, authors, languages, country origins, institutions, citations and journals of the published documents were evaluated. Results: A total of 4877 publications was evaluated in this bibliometric study. The total publication counts about PPV had been increased from the year 2009 (368 documents) to 2018 (607 documents). The mostly encountered topics were PPV combined with an anterior segment procedure (670 documents, 13.7%), rhegmatogenous retinal detachment (393 documents, 8.1%), and macular hole (388 documents, 8.0%). The most published document type were research articles and case reports (4029 documents, 82.6%). University of London was the most productive institution (131 documents, 2.7%). The journal that published the most about PPV was 'Retina' (615 documents, 12.6%). The average citation count per PPV document was 7.9. Conclusions: In the area of PPV related publications, the most encountered topics were PPV combined with an anterior segment procedure and rhegmatogenous retinal detachment surgery in the last decade. © 2020 Gazi Eye Foundation.
