Figure 1.

Transillumination pictures of representative lenses showing the state of lens transparency in different groups. As apparent, the lenses of the animals given sodium selenite are severely cataractous (U), the opacity being more dense in the nuclear than in the surrounding areas. In the majority (64%) of the caffeine treated pups (T₁), the lenses remained largely transparent. T₂ represents 36% of the caffeine treated animals where cataract prevention remained incomplete in comparison to T₁, but the severity of transparency loss was significantly less that that in group U. .
