Convergence insufficiency may be treated with convergence exercises prescribed by an eyecare specialist trained in orthoptics or binocular vision anomalies (see: vision therapy). Some cases of convergence insufficiency are successfully managed by prescription of eyeglasses, sometimes with therapeutic prisms.
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.
Orthoptists are mainly involved with diagnosing and managing patients with binocular vision disorders which relate to amblyopia, eye movement disorders, extraocular muscle balance such as with version, refractive errors, vergence, accommodation imbalances, positive relative accommodation and negative relative accommodation. They work closely ...
Vision therapy will allow individuals to enhance their vision through several exercises such as by strengthening and improving eye movement. [52] There is recent evidence that stereoacuity may be improved in persons with amblyopia by means of perceptual learning ( see also: treatment of amblyopia ).
Principle of binocular vision with horopter shown. In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and ...
The Brock string is commonly employed during treatment of convergence insufficiency and other anomalies of binocular vision. It is used to develop skills of convergence as well as to disrupt suppression of one of the eyes. [1] During therapy, the one end of the Brock string is held on the tip of the nose while the other is tied to a fixed point.
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.
Although glasses and/or patching therapy, exercises, or prisms may reduce or help control the outward-turning eye in some children, surgery is often required. A common form of exotropia is known as "convergence insufficiency" that responds well to orthoptic vision therapy including exercises. This disorder is characterized by an inability of ...
