Figure 2. Micrographs of the rabbit ocular surface two weeks after transplantation of human conjunctival epithelia (CjE) sheets onto alkali-treated ocular surfaces. A, C: In these eyes with transplants, the ocular surfaces are smooth and show no fluorescein penetration. B, D: The eyes were treated exactly as A and C but without human CjE sheet application. Note the incipient corneal neovascularization in B and the extensive corneal epithelial defect in D. Representative images of eight grafted corneas are shown.
