Cytotoxic effects of internal calcium on lens physiology: a review

Curr Eye Res. 1985 Apr;4(4):453-9. doi: 10.3109/02713688509025160.

Abstract

While calcium is possibly involved in cataractogenesis, it is unquestionably involved in normal lens physiology. Numerous reports have documented the many cellular processes in other tissues affected by alterations in cellular levels of calcium. The homeostasis of the lens is no less dependent on the critical balance of intracellular calcium. With advances being made in calcium-sensitive microelectrodes and pioneering studies progressing in ion channel electrophysiology, interest in calcium metabolism in the lens has been intensified. This report is an attempt to review recent findings that deal solely with biochemical changes resulting from calcium imbalances in the lens interior.
