A population study of the normal cornea using an in vivo, slit-scanning confocal microscope
Hollingsworth, Joanna G., Perez-Gomez, Inma, Mutalib, Haliza A., & Efron, Nathan (2001) A population study of the normal cornea using an in vivo, slit-scanning confocal microscope. Optometry And Vision Science, 78(10), pp. 706-711.
PURPOSE: To document qualitative and quantitative changes in the normal, healthy human cornea with age using the confocal microscope. METHODS: The central corneas of 120 subjects (mean age, 41 years; range, 11 to 80 years) were examined using an in vivo slit-scanning real-time confocal microscope. Images of the corneal stroma and endothelium from both eyes of each subject were semiautomatically analyzed in an observer-masked, randomized manner. RESULTS: Anterior keratocyte density, posterior keratocyte density, and endothelial cell density were shown to be unaffected by the sex of the subject with p values of 0.46, 0.55, 0.50, respectively (multivariate analysis of variance). No statistically significant difference was detected between right and left eyes for all corneal layers examined. The anterior keratocyte density, posterior keratocyte density, and endothelial cell density decreased at a rate of 0.48, 0.22, and 0.33% per year, respectively. A positive correlation was found between the coefficient of cell variation and age. CONCLUSIONS: This data constitutes essential normative data that can be used as a control in further research into abnormal corneal conditions.
Impact and interest:
Citation counts are sourced monthly from and 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.
