There are no differences in corneal endothelial cell density between emmetropic, myopic and hyperopic subjects

The objective of this study was to analyse the differences in corneal endothelial cell density between emmetropic, myopic and hyperopic subjects. Corneal endothelial cell density (cells/mm2) was analysed in 30 emmetropic (n=30; 27.3±4.0 years old), 30 myopic (n=30; 26.6±4.1 years old) and 30 hyperopic (n=30; 26.8±4.4 years old) subjects. The mean of three consecutive measurements of corneal endothelial cell density was obtained by means of no contact specular microscopy (Topcon SP-2000P no contact specular microscope, Topcon Corp., Tokyo, Japan). Corneal endothelial cell density ranged from 2833 to 3300 cells/mm2 (mean±SD, 3076±123 cells/mm2), from 2825 to 3316 cells/mm2 (mean±SD, 3048±152 cells/mm2), and from 2820 to 3262 cells/mm2 (mean±SD, 3033±115 cells/mm2) in emmetropic, myopic and hyperopic eyes respectively. No significant differences between emmetropic, myopic and hyperopic eyes were found (p=0.404). In sum, there is no difference in corneal endothelial cell density between emmetropic, myopic and hyperopic eyes.
