| CCT (μm) | With Vogt's striae | 463.20 ± 34.35 | 459.28 ± 35.49 | −3.92 ± 41.03 | 0.502 | 0.31 | 0.208 | −76.50 | 84.30 |
| Without Vogt's striae | 489.64 ± 35.99 | 481.38 ± 34.14 | −8.26 ± 42.50 | 0.176 | 0.27 | 0.620 | −75.00 | 91.60 | |
CCT: Central corneal thickness, r: Pearson correlation coefficient, LoA: Limits of agreement, SD: Standard deviation. There were no missing data. P-value <0.05 is statistically significant.
