Vertical heterophoria syndrome refers to a small vertical misalignment of the eyes, which has been hypothesized to arise from utricular or brainstem damage. A study, somewhat limited by excluding participants with binocular vision anomalies, found that methods that exercise convergence and accommodation independently are most effective ( Horwood & Toor, 2014 ).

Although VH was first described in the 19th century12, the medical community has made little progress in identifying and treating this condition, most likely because the standard vision alignment tests are not sensitive enough to find these subtle misalignments1,2,13,14,15,16,17,18,19,20.

Vertical Heterophoria - Focus Vision Therapy In the CITT study, the group that benefitted most from treatment had a longer duration of treatment and included procedures ( Table 10.2 ) designed to target fusional vergence and others aimed at overall convergence, with the therapist able to freely manipulate vergence and accommodative demand using multiple procedures ( Scheiman et al., 2010 ). .

There are three main strategies for the management of decompensated heterophoria: eye exercises (vision therapy), refractive Chapter 3 -Binocular vision and accommodative anomalies correction, or . The convergent fusional reserves, near point of convergence, near exophoria, and CISS symptoms improved significantly, most markedly in the two groups receiving office-based therapies. Note that in all cases the patient should be asked to report that doubling has been observed, in the sense that the target is seen to break into two and the images drift apart.
