Figure 4. Segmented epithelium at peripheral temporal region of the cornea.

Figure 4

The edge of Bowman’s layer was chosen as the landmark. The epithelium toward the apex was outlined using custom software. The 1000 pixels, equal to chord distance of 3.78 mm, from the landmark toward the apex were used to yield the peripheral epithelial thickness in each of the 10 zones.
