A bibliometric and visualized analysis of choriocapillaris from 2013 to 2023

To assess the current research status and emerging trends of the choriocapillaris (CC) by bibliometric analysis.

Publications spanning from January 2013 to May 2023 were retrieved on June 27th, 2023, using the Web of Science Core Collection. Bibliometric and visualized analyses were performed employing the bibliometrix, CiteSpace and VOSviewer.

A total of 1563 papers met the inclusion criteria, and a publication growth trend was observed. The United States was the leading country in the CC field. Retina and Investigative Ophthalmology & Visual Science stood out as highly impactful and prolific journals. Research topics in the CC field encompassed choroidal neovascularization, choroidal thickness, central serous chorioretinopathy, age-related macular degeneration, myopia, choroidal vascularity index, and diabetic retinopathy, based on the co-citation analysis. The keyword "high myopia" experienced a burst lasting until 2023.

In the past decade, research in the field of CC has flourished due to recent advancements in choroidal imaging; with focus shifting towards elucidating its role in various diseases. This will provide novel insights into managing chorioretinal diseases and vision-preserving interventions.
