The clinical manifestations of congenital cataract

Fetal congenital cataract in the process of crystal growth stunting results. Performance for various forms of turbidity. Its causes are two types: One is the decision by genetic factors, Most are autosomal dominant inheritance. Second is the mother during pregnancy or embryos lesions on embryonic crystal damage, and often associated with other ocular and systemic congenital malformation. Clinical manifestations 1. All cataract lens completely turbid. 2. Polar cataract (polar cataract) at the front pole and two posterior pole. LOS district at around capsule for the limitations of turbidity, geostationary and polar turbidity after a greater impact on the eyesight. 3. Around nuclear cataract (perinuclear cataract) on the crystal fetal lamellar or nuclear opacity zoster, the impact depends on the visual opacity area the size and density. 4. Flower coronavirus cataract (coronary cataract) for the bilateral, symmetrical peripheral cortical opacity. After that Crystal mydriasis peripheral cortical layer many sizes, short rod turbidity,arrangement shaped like a Corolla, still, more does not affect eyesight.
