All strains shown in Figure 1 were evaluated but only strains with abnormalities are shown. For incidence, the numerator indicates the number of mice or eyes affected and the denominator indicates the total number analyzed. The mice were 6 to 12 months old at the time of analysis and were not studied at other ages unless indicated. Histological analysis confirmed these observations and also identified calcified cyst like structures in the iris epithelium of strains SB/Le and SEC/1ReJ. A low incidence of corneal scarring was noted in some strains and likely resulted from a scratched cornea. Previously described retinal degeneration [[81]] caused by homozygosity for the Pde6brd1mutation was noted in strains SB/Le, ST/bJ, BUB/BnJ, CBA/J, C3H/HeJ, SJL/J and SWR/J.
