Leber's congenital amaurosis (LCA) is a collection of inherited, degenerative eye disorders that can reduce the strength of visual clarity or sharpness in infants and can cause childhood blindness. [ 14 ] [ 15 ] These eye disorders are mostly autosomal recessive diseases, and diagnoses of LCA are linked to multiple gene variants, including the ...
Globally, the number children with blindness is approximately 1.4 million, representing 4% of the global blind population, and an additional 17.5 million are at risk of developing poor vision. [31] Although this number is significantly lower than the number of blind adults, the estimated economic and social burden of blindness for children is ...
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.
Congenital cataracts are responsible for nearly 10% of all vision loss in children worldwide. Congenital cataracts are one of the most common treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1 to 6 cases per 10,000 live births.
ONH is the single leading cause of permanent legal blindness in children in the western world. [12] The incidence of ONH is increasing, although it is difficult to estimate the true prevalence. Between 1980 and 1999, the occurrences of ONH in Sweden increased four-fold to 7.2 per 100,000, while all other causes of childhood blindness had declined.
Retinopathy of prematurity (ROP), also called retrolental fibroplasia (RLF) and Terry syndrome, is a disease of the eye affecting prematurely born babies generally having received neonatal intensive care, in which oxygen therapy is used because of the premature development of their lungs. [2]
Approximately 2/3 of all cases of anophthalmia are determined to be of genetic basis. Anophthalmia is one of the leading causes of congenital blindness and accounts for 3-11% of blindness in children. [20] Anophthalmia and microphthalmia together make up 1.7-1.8% of reconstructive surgical cases in laboratory of plastic surgery and ocular ...
