However, following trauma, fever, stroke, deconditioning, or sometimes for no apparent reason, one eye will aim higher than the other will. When mild and not enough to cause double vision this is called hyperphoria. If excessive to the point of causing double vision, it is termed hypertropia. In an effort to adjust to the vertical misalignment of the eyes, the person will frequently tip their head to mechanically help align the eyes. This in turn can cause disorders in the fluid of the inner ear and resultant dizziness and balance disorders.
Treatment is with therapy to correct the muscle imbalance and prisms.
Binocular Vision Dysfunction Binocular vision refers to how the eyes work together as a team. Following trauma, fever, stroke, deconditioning, or sometimes for no apparent reason dysfunctions can occur causing the eyes to be weak or overactive. When this occurs, the eyes will manifest a tendency to drift outwards or inwards. This in turn can cause eyestrain, double vision, muscle spasm and excessive peripheral visual stimulation, which in turn can trigger dizziness and balance problems. Treatment is with lenses, prisms and therapy.
