CALCIUM IN RELATION TO CATARACT

Abstract

Many empiric studies have been made with the hope of discovering something that would prevent the dreaded onset and progress of cataract or restore useful vision to those afflicted. It is a fact that in certain eyes there are observed opacities which have developed to a certain stage and then, because the factor that produced them has become inactive, no longer progress. The opacity is pushed toward the center of the lens as more clear cortex is formed by the equatorial cells. The observation time and again of this phenomenon, rather than the reports of spontaneous absorption or retardation, arrest or cure of cataracts by various local and systemic measures, constitutes a valid reason for continuing the study of the nonsurgical treatment for cataract, both from the clinical standpoint and by fundamental investigations into the nutrition and metabolism of the crystalline lens.
