Congenital cataracts are a lens opacity that is present at birth. Congenital cataracts occur in a broad range of severity. Some lens opacities do not progress and are visually insignificant, others can produce profound visual impairment. Congenital cataracts may be unilateral or bilateral. They can be classified by morphology, presumed or ...
Childhood cataract is cataract that occurs at birth or in childhood. [1] It may be congenital or acquired. Congenital cataracts are defined as the presence of lens opacification during childhood. [2] About 1.14 million children in the world are blind. [3] Cataracts are the leading cause of blindness in children. [4]
Understanding the genetics of cataracts can shed light on how the lens itself works, and who might be at higher risk for cataracts. Although congenital cataracts are relatively rare, studying them ...
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.
Bilateral cataracts in an infant due to congenital rubella syndrome. Signs and symptoms vary depending on the type of cataract, though considerable overlap occurs. People with nuclear sclerotic or brunescent cataracts often notice a reduction of vision. Nuclear cataracts typically cause greater impairment of distance vision than of near vision.
Hypomyelination-congenital cataract syndrome is a rare autosomal recessive hereditary disorder that affects the brain's white matter [1] and is characterized by congenital cataract (or cataracts that begin in the first two months of life), psychomotor development delays, and moderate intellectual disabilities.
Congenital rubella syndrome (CRS) occurs when a human fetus is infected with the rubella virus (German measles) via maternal-fetal transmission and develops birth defects. [1] The most common congenital defects affect the ophthalmologic, cardiac, auditory, and neurologic systems.
Congenital cataract-hypertrophic cardiomyopathy-mitochondrial myopathy syndrome, Cardiomyopathy and cataract. Autosomal recessive pattern is the inheritance manner of this condition: Symptoms: Cataracts, fatigue, muscle weakness, hypotonia, lactic acidosis, and cardiomyopathy. [1] Usual onset: Birth: Causes: Mutations in the AGK and SLC25A4 ...
