Figure 2

Perfused porcine globe (Example 1). (a) Photo of an aqueous vein and branched vein segments, (b) corresponding photoacoustic image, (c) tracked points in 3-D of the circled vein, where blue and red points are at IOPs of 6.2 and 18 mmHg, respectively, and the green displacements of select identical points showing clear outward movement as the IOP increases, (d) mesh with tetrahedral elements, and the spatial strain fields of (e) normal strain \(\varepsilon\)XX at 18 mmHg and (f) \(\varepsilon\)ZZ at 18 mmHg. In (a,b), the sclera under the red dashed line indicates a region of deeper veins. (d-f) were generated using LS-Dyna R9.0, http://www.lstc.com/products/ls-dyna.
