Abstract
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
[1]. 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
[2]. Debate continues, however, with regard to the exact causes of
cataractogenesis and ways in which it may be prevented [1].
