Fig 4. CR ratio following administration of 6-fold diluted PAI.

PAI solution diluted 6-fold with saline was administered to rabbit eyes. Ten seconds later, the eyes were irrigated with saline or left unwashed. At 0, 10, 30, 60, and 120 min (A), and 0, 30, 60, and 96 h (B) after the initial administration, the CR ratio was measured using a CR device. ●: Non-washed, ■: Washed, *p<0.05 versus control, N = 6.
