Abstract

The present invention provides a screening method and device for the risk of congenital cataract, comprising: obtaining samples to be classified; classifying the samples to be classified by machine learning methods to obtain classification prediction results; determining the screening results according to the classification prediction results; wherein, The screening results include normal and congenital cataracts, which is non-invasive, low-cost, and has high detection accuracy.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a screening method and device for congenital cataract risk. Background technique [0002] A congenital disorder is one that is present at birth or discovered shortly after birth. Mothers exposed to environmental harmful factors during pregnancy, such as pesticides, organic solvents, heavy metals and other chemicals, or excessive exposure to various rays, or taking certain drugs, or infected with certain germs, may cause congenital abnormalities in the fetus. Because the treatment of congenital diseases is difficult and the effect is relatively poor, the prevention of congenital diseases in newborns is the primary task of the management strategy of congenital diseases. [0003] Traditional congenital diseases include genetic screening and prenatal examination before the baby is born, as well as routine disease screening of newborns after birth. However, these tests are invasive...
