What is congenital cataract

Fetal development is in the process of crystal stunting results, Performance parts for the full range of the crystal morphology and turbidity.
Causes: There are two major reasons for its incidence categories: First, by genetic factors, are mostly autosomal dominant inheritance, and the second is the mother during pregnancy or fetal systemic disease of the damage caused by crystal embryos.
Clinical manifestations: Apart from some congenital cataract lens opacity, there are systemic and other ocular abnormalities, and sometimes their eye syndrome is certain abnormal performance of the lens opacification by the shape, location, classification causes:
1, the former extremely cataract: Crystal in the embryonic period of foam from the outside leaves completely out in those embryos, binocular lens opacification symmetry, the anterior capsule in Crystal right in the middle into a dot-shaped, and sometimes slightly prominent in the anterior chamber was pyramid-shaped, general scope smaller. Does not affect eyesight.
2, after a cataract: Crystal at its posterior capsular opacity center, such as cataract Although more static, but close to eyeball optical center, so the visual impact.
3, around nuclear cataract: double of lamellar cataract, cataract children common, bilateral symmetry, such embryos nuclear cataract lens more than transparent, characterized by the focus on the fetus lamellar nuclear opacity. There are many around the nuclear opacity with enveloping shape, and there are many white opacity of the cable-like riding in the belt-shaped cross-opacity of the equatorial zone, it said around nuclear cataract, and the extent of its decline in the central vision area of nuclear size and density turbidity relevant.
