Ocular surface cooling in dry eye - a pilot study
Morgan, Philip B. , Tullo, Andrew B. , & Efron, Nathan (1996) Ocular surface cooling in dry eye - a pilot study. Journal of the British Contact Lens Association, 19(1), pp. 7-10.
Infrared thermography was employed to measure the change in ocular surface temperature on eye opening within a group of 11 dry-eye patients and seven control subjects. Qualitatively, the colour-coded thermograms were found to be disorganised and irregular in the dry-eye group. Quantitatively, the decrease in temperature was found to be much more rapid in the dry-eye group (0.88 ± 0.23 degrees Celsius in 7s) compared with the control group (0.21 ± 0.27 degrees Celsius) (P<0.0001). This faster rate of cooling can be explained in terms of a greater evaporation rate and the increased ocular surface temperature on eye opening in a dry eye. This observation, if confirmed on a larger study group, potentially offers a new, objective, non-invasive system for analysis of the tear-film and dry-eye therapies.
Impact and interest:
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.
