What is the reason of natural blindness?

First, congenital cataract is a common eye disease in children. Partial or total opacity of the lens in the first year after birth is called congenital cataract.

Second, because of the factors that cause lens opacification at the time of birth, cataract has not yet appeared; Lens opacity occurs within one year, so congenital cataract is also known as infant cataract.

Third, congenital cataract can be familial or sporadic; It can be unilateral or bilateral; It may be accompanied by other ocular abnormalities. In addition, a variety of genetic or systemic diseases can also be accompanied by congenital cataract.
