The lens epithelium of American cocker spaniels with inherited and non-inherited lens cataracts.

The normal lens epithelium of American cocker spaniels exhibits a monolayer of cells similar to that seen in other animals. The lens epithelium from spaniels with presumed inherited cataracts shows a lack of cell division and a decrease in cell density. Lens epithelial preparations from spaniels with presumed non-inherited cataracts show a multilayering of cells with several mitotic figures.
