Table 3. The thickness of the corneal endothelium lay in various ages of each experimental group.

Groups	1 m (μm)	6 m (μm)	12 m (μm)
R1	1.60±0.22 (n=40)	1.31±0.29 (n=36, p=0.078 versus 1 m)	0.93±0.46 (n=38, *p=0.023 versus 6 m)
P8	1.90±0.23 (n=36)	0.96±0.38 (n=38, *p=0.000 versus 1 m)	0.54±0.38 (n=38, *p=0.014 versus 6 m)
p value (R1 versus P8)	p=0.067	*p=0.031	*p=0.019

In the headings, m is the age in months. In the body of the table, n is the number of fields examined from the three individual specimens of each experimental group. The thickness of the corneal endothelium decreased significantly in the 12-month-old in the R1 strain group while it decreased significantly in both the 6-month to 12-month-old specimens in the P8 strain group. When comparing the two strain groups, the thicknesses of the corneal endothelium are significant thinner in 6-month- and 12-month-old specimens of the P8 strain than in that of the R1 strain group.
