Sarahs NeuroVisual evaluation revealed that she had a subtle vision misalignment (VH). Recently published research theorized that VH is occurring due to a lack of coordination between the two main vertical eye alignment mechanisms, the vision (or oculomotor) system and the balance (or vestibular) system, and that the initial problem is a faulty vertical alignment signal from the vestibular system. A single aperture is used to train relative convergence and two apertures are used to train relative divergence. Poor sleep habits and allergies are other conditions that may be confused with vertical heterophoria. The stereoscope cards appropriate for this should have most of the picture common to both eyes, so fusion can take place, but have small parts of each eyes picture presented to only one eye to act as monocular markers.
