FIGURE 4

Bright-field images of the TM when exposed to (a) AE; (b) AE + PEG with a molecular mass of 511 kDa at a concentration required to apply an osmotic pressure of 10 kPa at 1 h; and (c) AE at 2 h. Images were normalized by dividing each pixel by the average value of its neighbors in a 51 × 51 pixel region. One longitudinal and radial fiber, Hensen's stripe and limbal attachment have been traced in panel a. The value Δt, shown in the lower right of panels b and c, represents the time elapsed since the image in panel a was obtained.
