Table 2.
Contralateral comparison of endothelial cell parameters was measured by specular microscope between keratoconus (KCN) eyes with Vogt's striae and those without Vogt's striae.

CCT: Central corneal thickness, ECD: Endothelial cell density, CV: Coefficient of variation, HEX: Hexagonal cells, SD: Standard deviation. There were no missing data. P-value <0.05 is statistically significant.
a
Wilcoxon signed ranks test.
b
Paired-samples T test, bold values are significant.
