Representative images of TEM. The collagen in the non-irradiated corneal lamellae (A) arranged in a compact structure. Keratocytes in the non-irradiated one were long spindle (B). After 10 Gy or 20 Gy X-ray irradiation, collagens were arranged in a loose formation that was still similar to the normal corneal matrix fiber. (C, E), and keratocytes nuclear membrane turn to shrivel (D, F). After 50 Gy or 100 Gy irradiation, the collagen arranged in an obvious loose formation (G, I). After 100 Gy irradiation, keratocytes nuclear membrane remarkably disrupted, and autophagic vacuoles were observed (J). Moreover, keratocytes nuclear membrane disruption also occurred in 50 Gy X-irradiated the corneal lamellae (H).
