Anterior cortical cataract developed in Epha2-knockout mice. Representative ophthalmic images of Epha2+/+ (A, B,
C) and Epha2+/− (D, E,
F) mice at 11 ± 3, 18 ± 3, and 38 ± 3 weeks of age and Epha2−/− (G,
H) mice at 11 ± 3 and 18 ± 3 weeks of age, on C57BL/6J background, are shown. Epha2−/− mice progressively developed severe ACC by 18 ± 3 weeks of age, panel H, and Epha2+/− mice by 38 ± 3 weeks of age, panel F. The bottom right panel shows cross-section illumination images of cortical cataracts seen in panels H and F. Lenses of Epha2+/+ mice remained relatively clear up to 38 ± 3 weeks of age, panel C, and later (not shown). Magnification, times 40.
