Abstract
A new type of probe devised for the Goldmann applanation tonometer depends for its operation on the difference in critical angles for glass-tear fluid and glass-cornea interfaces. The probe failed to work correctly, and subsequent investigations to determine why were directed at the physical structure of the pre-corneal tear film. Photometry indicated that the anterior surface of the cornea in vivo reflected up to 8% of the incident light, more then seems generally supposed. Calculations of the anterior corneal surface reflectance indicate that two or three layer models of the pre-corneal tear film fit the observations. Slit lamp observations indicated that the reflectance of the corneal epithelium is much lower than that of the endothelium.
Citations:
Citation countsare sourced monthly from Scopus and Web of Science citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
