Abstract
Recent advances in understanding the mechanism of selenite cataract have resulted from locating the cleavage sites on proteolyzed β-crystallins from the cataract, mimicking the insolubilization of crystallins found in the cataract in an in. vitro system, studying cataract produced in lenses cultured in selenite, and permanently or temporarily reducing the rate formation of selenite cataract by use of various inhibitors. The present review discusses the selenite cataract as a useful model for understanding the role calcium-induced proteolysis in cataract formation.
