Cataract, Illustration
2D illustration showing an eye affected by cataracts. A cataract is a denaturation of proteins in the eye's lens that produces an opacity and consequent loss of sight of varying severity. This mature cataract appears as a white mass behind the iris. The most common cause is aging, with the cataract developing over a number of years. Cataracts caused by diseases are relatively rare: examples include diabetes, Wilson's disease and severe eczema. Drugs such as steroids and trauma induced by injury or radiation are other causes. Congenital cataracts are rare. Surgery is the only effective form of treatment.
