Oliver Sacks was the first to make the story of Susan Barry, whom he nicknamed "Stereo Sue", known to the general public.. Stereopsis recovery has been reported to have occurred in a few adults as a result of either medical treatments including strabismus surgery and vision therapy, or spontaneously after a stereoscopic 3D cinema experience.
Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.
The first known case of published recovery from blindness is often stated to be that described in a 1728 report of a blind 13-year-old boy operated by William Cheselden. [5] Cheselden presented the celebrated case of the boy of thirteen who was supposed to have gained his sight after couching of congenital cataracts.

Additionally, children affected by childhood dementia are often misdiagnosed with: Autism [16] [9] [17] Developmental or intellectual delay [16] [9] ADHD [9] Others [9]
Congenital blindness is a hereditary disease and can be treated by gene therapy. Visual loss in children or infants can occur either at the prenatal stage (during the time of conception or intrauterine period) or postnatal stage (immediately after birth). [3] There are multiple possible causes of congenital blindness.
The diagnosis of childhood blindness is done via methods to ascertain the degree of visual impairment in the affected child. Early detection is essential to provide early intervention to children. The American Academy of Ophthalmology recommend various screening methods starting in newborns and spanning throughout childhood in order to assess ...
While cortical blindness results from lesions to primary visual cortex, visual agnosia is often due to damage to more anterior cortex such as the posterior occipital and/or temporal lobe(s) in the brain. [2] There are two types of visual agnosia, apperceptive and associative. Recognition of visual objects occurs at two levels. At an ...
Despite dyschronometria's easily recognizable symptoms, the fact that they may also be present in other cerebellar ataxias can make diagnosis difficult. Other ataxias may also have symptoms that affect gait, speech, thought process, spatial awareness, and time orientation used in their diagnoses, covering up the fact that most of these patients ...
