Anterior cortical cataract developed in Epha2-knockout mice on FVB:C57BL/6J mixed background. Representative ophthalmic images of Epha2+/+ (A, B,
C) and Epha2+/− (D, E,
F) mice at 18 ± 3, 38 ± 3 and 64 ± 3 weeks of age and Epha2−/− (G,
H) mice at 18 ± 3 and 38 ± 3 weeks of age, on FVB:C57BL/6J (50:50) mixed background, are shown. No cataract was evident in Epha2+/+, C, or in Epha2+/−, F, mice up to 64 weeks of age. Epha2−/− mice progressively developed severe ACC by 38 ± 3 weeks of age, H. The bottom right panel shows cross-section illumination images of the Epha2−/− and Epha2+/− eyes seen in panels H and F, respectively. Magnification, times 40.
