Congenital Cataract

(Childhood cataract)

A congenital cataract (cataract) is a cloudy lens showing either at birth or shortly thereafter.

A congenital cataract may occur sporadically or by chromosomal anomalies, metabolic disorders (eg. B. galactosemia), intrauterine infection (z. B. rubella) or other maternal diseases are caused during pregnancy. Congenital cataracts can also be an isolated anomaly, which is often inherited familial autosomal dominant.

Congenital cataracts can also be an isolated anomaly, which is often inherited familial autosomal dominant. The cataracts, either centrally or in the nucleus of the lens relating to the lens cortex below the front and rear lens capsule. They can occur uni- or bilateral. When the red light reflex is not verified or there is no ophthalmological examination at birth, a cataract may go unnoticed. As with other cataracts, the milky lens obscures vision. The cataract prevents the view of the Optikusscheide and vessels and should be evaluated by an ophthalmologist. The cataracts are removed by being sucked by a small incision. In many children, intraocular lenses can be implanted. The post-operative care with glasses, contact lenses, or both, is usually required to achieve good vision. After removal of a unilateral cataract the quality of images in the treated eye is worse than in the other eye (assuming the other eye is healthy). Since the better eye is preferred, the brain suppresses the poorer image, and amblyopia develops. Therefore, an effective amblyopia therapy for the treated eye is important to ensure the development of normal vision. Some children can not achieve good visual acuity because they suffer from accompanying structural defects. In contrast, children develop in which both sides cataract was removed and where the image quality is comparable in both eyes, often in both eyes the same vision. Some cataracts are partially (rear lens nucleus) and a murky during the first 10 years of life. Eyes with a partial cataract have regarding eyesight better long-term prognosis.
