Cataracts
A cataract is an opacity that develops
in the lens of the eye or in its envelope. Age-related
cataract may result in increased power of the crystalline
lens, causing near-sightedness [myopia]. It can also
lead to gradual yellowing and opacification of the lens;
reducing the perception of blue colours. Untreated Cataracts
can cause vision loss and blindness.
Cataracts are the leading cause of blindness in the
world. In the United States, age-related lenticular
changes have been reported in:
- 42% of those between the ages of 52 to 64
- 60% of those between the ages 65 and 74, and
- 91% of those between the ages of 75 and 85
Causes Of Cataracts
Cataracts develop from a variety of reasons, including:
- long-term ultraviolet
exposure
- exposure to radiation
- secondary effects of diseases such as diabetes
- advanced age
- genetic factors are often a cause of congenital
cataracts - predisposing someone to cataracts at an
earlier age
Cataracts may also be produced by eye injury or physical
trauma.
