[10] Both positive fusional vergence (PFV) [11] and negative fusional vergence (NFV) [12] can be trained, and vergence training should normally include both. [13] [14] Surgical correction options are also available, but the decision to proceed with surgery should be made with caution as convergence insufficiency generally does not improve with ...
The prism fusion range (PFR) or fusional vergence amplitude is a clinical eye test performed by orthoptists, optometrists, and ophthalmologists to assess motor fusion, specifically the extent to which a patient can maintain binocular single vision in the presence of increasing vergence demands.
Accommodative vergence: blur-driven vergence. Fusional vergence (also: disparity vergence, disparity-driven vergence, or reflex vergence [2]): vergence induced by a stimulus to binocular fusion. Proximal vergence: vergence due to the awareness of a fixation object being near or far in the absence of disparity and of cues for accommodation. This ...
Vision assessment and cycloplegic refraction should be done. If there is any refractive errors, it should be corrected before considering orthoptic treatments.The accommodative infacility is commonly treated with vision therapy/orthoptics; one study found that 12 weeks of treatment had a significant effect on visual accommodation.

This is when it is said to be "compensated". When fusional reserve is used to compensate for heterophoria, it is known as compensating vergence. In severe cases, when the heterophoria is not overcome by fusional vergence, sign and symptoms appear. This is called decompensated heterophoria.
