Figure 2. Relationship between corneal thickness and age in normal corneas and corneas with Fuchs dystrophy.

Figure 2

Left, In normal corneas, central corneal thickness (CCT) was not correlated with age (r=0.15, p=0.08, n=267), whereas peripheral corneal thickness at 4 mm from the center (PCT4) decreased with age (r= -0.33, p<0.001, n=254). Right, In corneas with Fuchs dystrophy, CCT was not correlated with age (r= -0.08, p=0.24, n=117), whereas PCT4 was correlated with age (r= -0.17, p=0.04, n=107) Although PCT4 was higher in Fuchs dystrophy (650 ± 51 μm) compared to normal corneas (643 ± 43 μm, p=0.002 after adjusting thickness for age), the difference was small and clinically insignificant. All data were measured with the scanning-slit pachymeter. Solid lines, regression lines for PCT4.
