Surgical correction of cataracts now has a high success rate and results in restored sight for affected patients. Researchers, however, continue to try and find ways to prevent or delay development of the condition. The ability to delay the onset of cataract by 10 years would eliminate the need for one-half of all cataract surgeries. This paper discusses the relationship of blood glucose and blood pressure to the development of age-related cataracts. Cataract is defined as opacity of the crystalline lens, and development is influenced by a number of exogenous and endogenous factors. The greatest risk factor is age. Diabetes mellitus is also associated with the development of cortical and posterior sub capsular cataract . The Beaver Dam Eye Study and the Cataract Patient Outcomes Research Team have reported an association between age-related cataracts and systemic cardiovascular or atherosclerotic disease . Debate continues, however, with regard to the exact causes of cataractogenesis and ways in which it may be prevented .
