Sugar cataracts in Mongolian gerbil (Meriones unguiculatus).

Mongolian gerbils (Meriones unguiculatus) given a 50% galactose diet developed cataracts similar to those produced in rats maintained on the same diet. This report describes the various stages through which the cataracts progressed. The first sign of a cataract appeared 24 hr after feeding gerbils on the high galactose diet.

Refractive change in alloxan diabetic rabbits. Control by flavonoids I.

The rabbit eye is hyperopic by approximately 4D. The induction of diabetes leads to a further enhancement in the degree of hyperopia. This enhancement is attenuated substantially by flavonoids as inhibitors of aldose reduction.
