Smoking May Lead to Cataract in Aging Population..!
« on: October 27, 2012, 06:34:03 AM »
Cigarette smoking is a well-known risk factor for a wide-range of diseases. Now, scientists have evidence that smoking may also increase the risk of age-related cataract, the leading cause of blindness and vision loss in the world.
The results showed that every individual that ever smoked cigarettes was associated with an increased risk of age-related cataract, with a higher risk of incidence in current smokers. In the subgroup analysis, former and current smokers showed a positive association with two of the sub types:
Nuclear cataract, when the clouding is in the central nucleus of the eye, and sub scapular cataract, when the clouding is in the rear of the lens capsule. The analysis found no association between smoking and cortical cataract, in which the cloudiness affects the cortex of the lens.
