Copper levels in human mixed, nuclear brunescence, and posterior subcapsular cataract.

Abstract

The study was undertaken to determine the copper content in different human cataractous lenses. The level of copper increased with increasing age in nuclear brunescence and mixed cataractous lens and a low amount of copper was observed in the posterior subcapsular cataractous lens with increasing age. Cataractous lenses of females have greater amounts of copper compared with males.
