N normal phenotype
vision/eye
• the lens nucleus is completely shifted to the anterior epithelium and is highly vacuolated
• the primary lens fiber cell have completely degenerated and the secondary fibers did not enlarge
• dense nuclear and subcortical cataracts
• degeneration of the primary lens fiber cells and failure of the secondary fiber cells to enlarge results in a very small lens
