Advancements and emerging trends in ophthalmic anti-VEGF therapy: a bibliometric analysis.

INTRODUCTION

Vascular Endothelial Growth Factor (VEGF) is associated with abnormal fundus neovascularization. Consequently, Anti-VEGF agents are vital for ophthalmic treatment. This paper reviews the application of anti-VEGF agents in ophthalmology over the past two decades with the aim of providing insights for further research.

METHODS

A meticulous search strategy was employed in the Web of Science Core Collection literature from 2003 to 2023 to gather relevant literature, which was then analyzed using VOSviewer, CiteSpace, and the R package Bibliometrix.

RESULTS

The study included 3,602 publications from 83 countries and 3,445 institutions. The United States and China have emerged as leading contributors in terms of the publication volume. Johns Hopkins University, the University of Sydney, and Genentech Inc were identified as frontrunners in this field. "Retina" had the highest publication volume, whereas "Ophthalmology" had the highest citation frequency. Among the 15,918 scholars, Bressler NM, Holz FG, Glassman AR, and Bandello F led in publication volume, while Brown DM was the most cited author. High-frequency keywords included "Endothelial Growth Factor," "Therapy," "Safety," and "Randomized Clinical Trial."

CONCLUSION

Anti-VEGF drugs have shown notable success in treating neovascular eye diseases, especially wet age-related macular degeneration and diabetic macular edema, focusing on clinical efficacy, injection regimens, and safety. Future directions include developing new anti-VEGF drugs, drug delivery systems, non-invasive administration, multi-target drugs, leveraging big data and artificial intelligence, and addressing the current treatment limits. Continuous innovation and method improvement in this field promise more breakthroughs, providing effective, safe, and economical options for eye disease treatment.
