Convergence Insufficiency. Other names. Convergence disorder. Specialty. Ophthalmology, optometry. Convergence insufficiency is a sensory and neuromuscular anomaly of the binocular vision system, characterized by a reduced ability of the eyes to turn towards each other, or sustain convergence.
Dyslexia, previously known as word blindness, is a learning disability ('learning difficulty' in the UK [6]) that affects either reading or writing. [1][7] Different people are affected to different degrees. [3] Problems may include difficulties in spelling words, reading quickly, writing words, "sounding out" words in the head, pronouncing ...
The concept of a perceptual noise exclusion deficit (impaired filtering of behaviorally irrelevant visual information in dyslexia or visual-noise) is an emerging hypothesis, supported by research showing that subjects with dyslexia experience difficulty in performing visual tasks (such as motion detection in the presence of perceptual distractions) but do not show the same impairment when the ...
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 the eyes to work together when used for near viewing, such as reading. Instead of the eyes focusing together on the near object, one deviates outward.
Fusional amplitude and relative fusional amplitude training are designed to alleviate convergence insufficiency. The CITT study (Convergence Insufficiency Treatment Trial) was a randomized, double-blind multi-center trial (high level of reliability) indicating that orthoptic vision therapy is an effective method of treatment of convergence ...
In the 1970s, a hypothesis emerged that dyslexia stems from a deficit in phonological processing, or difficulty in recognizing that spoken words are formed by discrete phonemes, for example, that the word CAT comes from the sounds [k], [æ], and [t]. As a result, affected individuals have difficulty associating these sounds with the visual ...
Dyslexia. Dyslexia is a disorder characterized by problems with the visual notation of speech, which in most languages of European origin are problems with alphabet writing systems which have a phonetic construction. [1] Examples of these issues can be problems speaking in full sentences, problems correctly articulating Rs and Ls as well as Ms ...
Dyslexia is a common language-based learning disability. Dyslexia can affect reading fluency, decoding, reading comprehension, recall, writing, spelling, and sometimes speech and can exist along with other related disorders. [15] The greatest difficult those with the disorder have is with spoken and the written word.
