Oxygen uptake profile of the human cornea
A polarographic oxygen sensor was used to measure corneal oxygen uptake (COU) centrally and 4mm proximally at nasal, temporal, superior, and inferior locations on 10 human subjects. The mean COU rates (±SEM) were 6.23 ± 0.25, 6.27 ± 0.40, 6.26 ± 0.35, 5.99 ± 0.29 and 6.26 ± 0.37 ml/cm2/h, respectively. There was no statistically significant difference between any of these measurements, thus confirming earlier predictions based on a rabbit eye model. The importance of retracting the eyelids for a prolonged period (5 min) prior to obtaining measurements of COU at the superior corneal site is demonstrated. This data provides a topographical baseline reference of COU, and has implications with respect to the monitoring of corneal disease and the design of contact lenses.
Citation countsare sourced monthly fromand 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 theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
