On Anterior Segment Optical Coherence Tomography Literature

Since its development, optical coherence tomography has gained popularity, and it is now routinely used to image the different parts of the eye. The goal of this study was to perform a bibliometric review and network visualization analysis of the available literature related to anterior segment optical coherence tomography.

Clarivate Web of Science Core Collection was used as a database to perform an advanced search with OCT and anterior segment-related keywords. The search was limited to titles, and all papers published in 2022 were excluded from the study. The “Analyze Results” and “Citation Report” functions were used to determine the most prolific authors, institutions, countries, journals, h-index of the research topic, and citations. VOSviewer 1.6.18 software was utilized for a network visualization analysis.

Totally, the study included 2734 papers, published in 383 different journals by 7387 authors. Article was the predominant type of publication (63.8%). Top-3 most prolific authors included Huang D (3.1%), Aung T (3.0%), and Li Y (2.5%). University of California system (5.5%), the United States (32.6%), and Investigative Ophthalmology & Visual Science (23.1%) were the most contributive institution, country, and journal, respectively. Even though the papers received 33843 citations from 14548 articles, 36.0% of them remained uncited. Research area h-index was 76. Network citation analysis revealed that most countries had highly developed interconnections while the United States, China, and Singapore were the most influential contributors.

The current study has provided a broad analysis of the publications related to anterior segment optical coherence tomography. Predominantly cited and consisting of articles, this research area has been expanding in the contex of highly developed interconnections between many countries.
