Summary
This bibliometric analysis maps the research landscape of corneal esthesiometry, identifying key contributors and trends. Findings highlight sensory physiology, ocular surface disease, and dry eye disease as central research areas.
Area of Science:
- Ophthalmology
- Neuroscience
- Biomedical Engineering
Background:
- Corneal esthesiometry is crucial for evaluating ocular surface health.
- Various eye and systemic conditions can affect corneal sensitivity.
- Recent years have seen the development of novel devices for measuring corneal sensitivity.
Purpose of the Study:
- To conduct a bibliometric analysis of corneal esthesiometry research.
- To identify key researchers, institutions, and countries in the field.
- To map the evolution and trends in corneal esthesiometry research from 2000-2024.
Main Methods:
- Systematic literature search of Web of Science and Scopus databases (2000-2024).
- Analysis of publication data using Microsoft Excel, Rayyan, and VOSviewer.
- Identification of influential authors, institutions, countries, and research clusters.
Main Results:
- 556 articles were analyzed, with A.J.M. Boulton being a highly impactful researcher.
- The University of Waterloo (Canada) was the most prolific institution; the United States led in publications.
- Key research clusters included neurophysiology, dry eye, ocular pathology, diabetic neuropathy, nerve assessment, and refractive surgery.
Conclusions:
- This bibliometric study provides a comprehensive overview of corneal esthesiometry research.
- Research predominantly focuses on sensory physiology, ocular surface disease, and dry eye disease.
- Emerging trends offer new clinical and research avenues for ocular surface condition management.
