Free radicals, ocidative stress and cataract

Richard A. Armstrong

Research output: Contribution to specialist publicationArticle

Abstract

In the more developed countries of the world, cataract accounts for approximately 20% of all registered cases of blindness. The development of cataract may be associated with many factors including ageing, trauma, burns, extreme heat or cold, certain systemic diseases such as diabetes, and inflammatory processes within the eye. However, recent evidence suggests that oxidative damage to the lens by free radicals may also be involved in the development of certain types of cataract. The objective of this article is to describe the formation and action of free radicals within the body and review the evidence that the development of cataract may be linked to oxidative processes.
