There is a suggestion, from a noncontrolled trial, that vertical fusional reserves could possibly be improved ( Luu et al., 2000 ), although the evidence base is weak for vision therapy to train any motor function other than convergent fusional reserves and near point of convergence. Each cat is incomplete in some way: an ear, an eye, or the tail is missing, so only when the two are fused is a complete cat formed ( Fig. While many people have never heard of Vertical Heterophoria (VH), for those affected by this little-known condition, life can be extremely difficult.

Sometimes you can feel the effects when driving on the freeway, at high speeds and rounding sharp turns. An alternative viewpoint is that the use of more than one technique may help the effect transfer into everyday vision ( Cooper et al., 1983 ), as may the use of different stimulus parameters ( Feldman, Cooper, & Eichler, 1993 ). is a good place to start if you suspect you may have VH.
