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 .
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.
In a small-scale study, adults whose reading difficulties due to convergence insufficiency had been unsuccessfully addressed by convergence exercises, base-in prism glasses or strabismus surgery showed improved reading after botulinum toxin therapy, maintaining improved reading remaining also after six months.
Cranial nerve disease, [3] convergence insufficiency. Treatment. Glasses, surgery [3] Frequency. ~2% (children) [3] Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. [2] The eye that is pointed at an object can alternate. [3]
Accommodative excess may occur secondary to convergence insufficiency also. In convergence insufficiency near point of convergence will recede, and positive fusional vergence (PFV) will reduce. So, the patient uses excessive accommodation to stimulate accommodative convergence to overcome reduced PFV.
Cause. Exophoria can be caused by several factors, which include: Refractive errors – distance and near deviation approximately equal. Divergence excess - exodeviation is more than 15 dioptres greater for distance than near deviation. Convergence insufficiency – near exodeviation greater than distance deviation.

Vision therapy has not been shown to be effective using scientific studies, except for helping with convergence insufficiency. Most claims—for example that the therapy can address neurological, educational, and spatial difficulties—lack supporting evidence.
