The first mention of an ocular derangement associated with diabetes mellitus apparently was made by Blancard in 1688; he described the case of a diabetic girl who became blind just before death. However, destruction of the optic nerve, not lenticular alterations, caused the blindness. Saunders, who in 1798 described the onset of bilateral cataract in a diabetic person, was the first to draw attention to the relation of the two conditions. Subsequently sporadic reports appeared so that by 1854, when His described the microscopic pathology of diabetic cataract, more than a dozen authors had already observed this type (Destouches; Jahn; Berndt; Unger ; Liman ; Himly ; T.
