Figure 4.

Polar vector plot maps showing the preferred orientation of collagen fibrils in the cornea and limbus of one control and one beg-affected eye at 1 month posthatch, sampled at 0.4 mm (control) and 0.5 mm (beg) intervals. It was necessary to scale down the larger plots for montage display, as indicated in the color keys below each map. Broken lines mark the boundaries of the three structurally distinct regions of the cornea (the central orthogonal region, the peripheral pseudoannulus, and the outermost radial zone). Open circles show radial fibrils in the outermost tissue that may associate with ciliary musculature, and red arrowheads highlight the superior globe position. Control data reproduced from Boote et al. (5).
