Cataract disease factor is the genetic
British scientists for the first time confirmed the occurrence of genetic factors in cataract play an important role, this discovery will help to find cataract-related genes to establish genetic test methods to identify which high-risk groups for cataracts. British scientists for the first time confirmed the occurrence of genetic factors in cataract play an important role, genetic factors than people have been condemned, such as smoking, unhealthy way of life is much greater.

"New England Journal of Medicine" (New England Journal of Medicine) magazine reported on the latest research results of cataract, the United Kingdom for the first time scientists have confirmed the occurrence of genetic factors in cataract play an important role, this discovery will help to find cataract-related genes, the establishment of genetic methods of examination in order to identify which high-risk groups for cataracts.

Cataract is a progressive lens opacity lesions, virtually all reached the age of 120 years people will have cataracts, smoking and steroid hormones induce cataract risk factors, diet quality and exposure to sunlight are also involved in cataract formation.

London St. Thomas Hospital, Dr. Christopher Hammond survey of 506 pairs of the age of 50-79 years old identical twins and fraternal twins of the sisters, for patients the degree of lens opacity score, and from a statistical point of view of the age, genetic factors , lifestyle and environmental factors on the impact of the disease and found that age could explain 38% of the lens lesions, while the genetic factor determines 48% of the lesions, other factors accounted for 14%.

Christopher Hammond pointed out that age is not the only risk factors and the decision 14% of lesions and other factors can not be ignored. Hammond colleague, Dr. Clare Gilbert believes that if in the future can use genetic methods to detect who is prone to cataracts, so these people can avoid exposure to various risk factors.
