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.
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 ...
Frederick Brock made many contributions to vision therapy, and his work focussed mainly on the application of vision training to the diagnosis and therapy of binocular dysfunction. [1] Brock trained his patients with rich stereo images which closely resembled the natural environment, and favored these over the use of (simplified) stereographs. [2]
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.
Maya Borenstein for LittleThings This "Figure Eight" exercise works the muscles differently by moving the head and keeping the eyes in place. Stare at a fixed object straight ahead.
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 ...
Binocular vision has further advantages aside from stereopsis, in particular the enhancement of vision quality through binocular summation; persons with strabismus (even those who have no double vision) have lower scores of binocular summation, and this appears to incite persons with strabismus to close one eye in visually demanding situations.
