Childhood cataracts are the primary cause of childhood blindness. [4] Childhood cataracts make up 7.4% to 15.3% of blindness in kids. [ 4 ] The prevalence of childhood cataracts ranges from 0.63/10,000 to 9.74/10,000 children, with a median of 1.71. [ 6 ]
The presence of cataracts in childhood or early life can occasionally be due to a particular syndrome. Examples of chromosome abnormalities associated with cataracts include 1q21.1 deletion syndrome , cri-du-chat syndrome , Down syndrome , Patau's syndrome , trisomy 18 ( Edward's syndrome ), and Turner's syndrome , and in the case of ...
Approximately 50% of all congenital cataract cases may have a genetic cause which is quite heterogeneous. It is known that different mutations in the same gene can cause similar cataract patterns, while the highly variable morphologies of cataracts within some families suggest that the same mutation in a single gene can lead to different ...
At some point—usually as you enter middle age—most people develop this eye condition, which is a clouding of the eye’s lens that can get progressively worse and impair your vision. According ...
Congenital cataract is a lens transparency disorder that occurs at birth or soon after. It is a leading cause of treatable vision loss or visual impairment in children. [2] A cataract is a clouding of the eye's lens. and is caused by a disruption in the normal structure or function of the lens protein, resulting in opacity.
The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma.
Oculocerebrorenal syndrome (also called Lowe syndrome) is a rare X-linked recessive disorder characterized by congenital cataracts, hypotonia, intellectual disability, proximal tubular acidosis, aminoaciduria and low-molecular-weight proteinuria.
A cataract is an opacity that develops in the crystalline lens of the eye. [9] The word cataract literally means, "curtain of water" or "waterfall" as rapidly running water turns white, so the term may have been used metaphorically to describe the similar appearance between mature ocular opacities and water fall.
