The section that outlined treatment only mentioned treating the cause of the dorsal midbrain syndrome. (which is obviously important)
I have done a lot of vision therapy with patients who have sufferend head traumas/strokes and have had the privelege of working with a lot of INOs, BINOs, WEBINOs, and dorsal midbrain patients. If the deviations are less than 15 prism diopters, vision therapy can be a very effective method of helping them overcome this.
