Figure 1. Illustration of the branching pattern of A
and C fiber nerve terminals within the cornea. A
and C fibers course together in the collagenous stromal layer. The nerve plexus in the stromal layer consists of extensively branching A
and C fibers. The fibers separate as they turn toward the superficial epithelial layers, where they terminate. Letters in parentheses correspond to the images in Figure 2. Adapted from MacIver and Tanelian (1993).
