[Clinical aspects and experimental findings in so-called senile cataracts. Determination of status]

Abstract

In this article the authors review the present state of our knowledge concerning senile cataract. Clinical observations, frequencies and prognosis, biochemical and biometrical results, etiology and pathogenesis as well as aspects of cataract epidemiology are presented. The available information indicates that the term "senile cataract" comprises a multiplicity of morphologically different types of opacities all characterized by unique properties. With respect to clinical relevance and for research purposes it is obvious and essential to replace the term "senile cataract" with more precise definitions appropriate to the type and localization of the opacity.
