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.
The TNO random dot stereotest (short: TNO stereo test or TNO test) is similar to the randot stereotest but is an anaglyph in place of a vectograph; that is, the patient wears red-green glasses (in place of the polarizing glasses used in the randot stereotest). Like other random dot stereotests, the TNO test offers no monocular clues. [4]
Stereo thresholds almost always improve, often several-fold, with training [8] and involve perceptual factors, differing in their particulars for each test. [9] This is most vividly evident in the time it takes to "solve" a random-dot stereogram rapidly decreases between the first exposure and subsequent views [ 10 ]
Vision rehabilitation (often called vision rehab) is a term for a medical rehabilitation to improve vision or low vision.In other words, it is the process of restoring functional ability and improving quality of life and independence in an individual who has lost visual function through illness or injury.
Many persons lacking stereopsis have (or have had) visible strabismus, which is known to have a potential socioeconomic impact on children and adults. In particular, both large-angle and small-angle strabismus can negatively affect self-esteem , as it interferes with normal eye contact , often causing embarrassment, anger, and feelings of ...
She was dubbed Stereo Sue by neurologist and author Oliver Sacks in a 2006 New Yorker article with that name. [ 1 ] Barry's first book greatly expands on Sacks' article and discusses the experience of gaining stereovision through optometric vision therapy , after a lifetime of being stereoblind .
