Figure 6.

A representative top view of a wedge (glaucomatous eye 122) from the dissection microscope with TM facing upward. AFM measurements started in the cornea on the right side, along the measurement line (yellow solid line) and toward the sclera. The measured compressive modulus of each location along the measurement line is indicated in blue dots. The area between the two dashed lines is taken as the TM region. Error bar denotes SD. Tissue was stiff in the cornea and decreased gradually as the measurement location moved posteriorly. Relatively low modulus was obtained in sclera region probably due to measurements on residual iris root or ciliary body. Sclera, cornea, TM, and sclera spur (SS) are labeled.
