Resumé

The ultrastructure of the ant-egg cataractous lens has been studied. Comparison of tissue demineralized by means of EDTA with untreated tissue showed the calcium salts in the ant-eggs to be mostly crystalline. A laminar appearance of the ant-egg seen in EDTA treated material suggested an intermittent growth of the structure. In the ant-eggs, as well as in some areas separate from these, membrane limited cytoplasmic bodies could be seen in many cases, the membranes of which were partly joint and partly separated by an electron dense material. It is suggested that the calcifications seen as the ant-eggs are secondary phenomena to an abnormal metabolism, morphologically seen as membrane limited cytoplasmic bodies.
