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 ...
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] This is dependent on factors like economic status but not gender or laterality.

The term childhood disease refers to disease that is contracted or becomes symptomatic before the age of 18 or 21 years old. Many of these diseases can also be contracted by adults. Some childhood diseases include:
Retinopathy of prematurity (ROP) is a cause of childhood blindness that can occur around the time of birth. Generally, measures taken to avoid preterm birth are also effective at preventing ROP. Babies delivered preterm, defined at or before 37 weeks of gestation, have incomplete development of the blood vessels supplying the retina. [21]
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
LCA symptoms typically begin in the first few months of life, most commonly with involuntary twitching of the eye . Affected infants may show misaligned eyes when looking at something ( strabismus ), aversion to light ( photophobia ), and poke or rub at their eyes (Franceschetti’s oculodigital sign). [ 9 ]
Periodontal Disease: Periodontal disease, also known as gum disease, can result in bone loss that supports the teeth. If a person loses enough bone, the teeth can become loose and cause gaps to form. [2] 3. Mesiodens: Mesiodens is an extra tooth that grows behind the front teeth. A mesiodens may push the front teeth apart to make room for ...
These symptoms generally begin before 8 months of age. [8] Ocular motor abnormalities occur early, and these are the most frequent early symptoms of AHC, particularly nystagmus. [4] [6] Almost 1/3 of people with this disorder had episodic ocular motor features within 1–2 days of birth.
