Congenital cataracts is a condition in which an individual is born with clouding of the lens of the eye, impairing vision. The lens is a clear structure within the eye which people see through and that helps to focus light. Seeing with cataracts is much like seeing through a foggy window. Autosomal dominant congenital cataracts is due to a genetic condition that is inherited from parents. In autosomal dominant congenital cataracts, a parent that was born with this condition typically has at least a 50% chance of having a child born with this condition. It is estimated that congenital cataracts are responsible for 5-20% of blindness in children worldwide, and in the US, about 3-4 children are born with congenital cataracts per 10,000 births. In autosomal dominant congenital cataracts, there is usually a family history which can aid in diagnosis. This condition must be corrected with surgery usually within the first two months of life.
