Figure 7.

Contour maps showing the spatial variation of the proportion of preferentially aligned collagen across one control and one beg chicken cornea at 9 months posthatch. Arrows indicate regions of heightened alignment in the peripheral cornea and limbus of the 9-month-old control eye, suggesting local reinforcement of tangential collagen. These are less pronounced in the bird affected by beg. The limbus is marked by a dotted line. Arrowheads highlight the superior globe position. Control data reproduced from Boote et al. (4).
