Slit lamp images of eyes. These pictures were taken at week 4 (1 day before sacrifice). A representative picture of the lenses observed for each group is shown. a: Lenses from control group were found to be clear with no detectable cataracts; b: Lenses from NACA group exhibited similar results as that of control, with no detectable cataracts; c: Lenses from Na₂SeO₃ group exhibited dense nuclear cataracts (80%); d: Lenses from NACA + Na₂SeO₃ group exhibited lower grade of cataracts
