Convergence insufficiency. 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 .
Accommodative insufficiency (AI) involves the inability of the eye to focus properly on an object. Accommodation is the adjustment of the curvature of the lens to focus on objects near and far. In this condition, amplitude of accommodation of a person is lesser compared to physiological limits for his age. [1]
Accommodative excess. In ophthalmology, accommodative excess (also known as excessive accommodation or accommodation excess) occurs when an individual uses more than normal accommodation (focusing on close objects) for performing certain near work. Accommodative excess has traditionally been defined as accommodation that is persistently higher ...
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 ...
June 27, 2024 at 11:26 AM. Chicago native Jeffrey Odwazny says he has been addicted to ultraprocessed food since he was a child. “I was driven to eat and eat and eat, and while I would overeat ...
Accommodative convergence is that portion of the range of inward rotation of both eyes (i.e., convergence) that occurs in response to an increase in optical power for focusing by the crystalline lens (i.e., accommodation ). [1] When the human eye engages the accommodation system to focus on a near object, signal is automatically sent to the ...
Communication accommodation theory ( CAT) is a theory of communication, developed by Howard Giles, concerning " (1) the behavioral changes that people make to attune their communication to their partner, (2) the extent to which people perceive their partner as appropriately attuning to them". [1] This concept was later applied to the field of ...
In recent years, however, successful improvements in persons with amblyopia, convergence insufficiency or other stereo vision anomalies have become prime examples of neuroplasticity; binocular vision improvements and stereopsis recovery are now active areas of scientific and clinical research.
