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.
[10] Both positive fusional vergence (PFV) [11] and negative fusional vergence (NFV) [12] can be trained, and vergence training should normally include both.
