Figure 11. Age-related cataract formation in Fgf9Y162C lenses.
C57BL/6J control (WT) and homozygous Fgf9Y162C (A/A) lenses are compared at three different stages (two, six, and twelve months of age). All lenses remained transparent at least up to six months of age. Some twelve-month-old mutant lenses developed an age-related polar cataract (arrow).
