Doi: 10.36351/pjo.v42i2.2206

Abstract

This study provides a bibliometric analysis of recent publications focused on Dry eye disease (DED) diagnostic tools.A comprehensive literature search was conducted in the Scopus database retrieved 2,625 records (2014–2024). After manual screening, 135 articles were selected. VOS viewer was used to perform co-authorship, country collaboration, and keyword co-occurrence analyses.Among 829 authors, 19 met the threshold of at least three publications. The United States, China, and Germany were leading contributors, with strong international collaboration networks. Keyword analysis from 1,576 keywords, 184 appearing ≥5 times, revealed thematic clusters around traditional diagnostic tests like the Schirmer test, modern imaging techniques like meibography, interferometry, and biochemical assessments like tear osmolarity. Overlay visualization showed a temporal shift toward more advanced and objective diagnostic methods between 2019 and 2024.The findings of the study provide valuable insights into global research trends and can guide future studies and clinical advancements in DED diagnosis.
