Difference between fresh and old feet. At 150 cms perfusion pressure the fresh feet showed no difference in IOP between 60 to 100 s (32.4 mmHg to 29.8 mmHg, p = 0.4)

T-test Fr/Old	20 s	40 s	60 s	80 s	100 s
150 cm	P = 0.40	P = 0.13	P = 0.26	P = 0.58	P = 0.57
100 cm	P < 0.02	P = 0.10	P = 0.24	P = 0.16	P = 0.10
50 cm	P < 0.0001	P < 0.01	P < 0.02	P < 0.03	P < 0.0001

There was no statistical difference between Fresh and Old feet perfused at 150 cms serum for 60 s (p = 0.256) and 100 s (p = 0.568)
