Eyes and Proprioception

The direct proprioceptive pathway in the visual system begins at the oculomotor muscle. To have a correct visual information on the position of our body and the objects we are seeing, we need information about the objects and about our eyes position. The information on the objects is carried out by the retina and visual pathways. The information about the eyes' position is carried out by proprioceptive pathways from the eye muscles. However, these two structures are not linked at eye-level but at brain-level.
Active prisms can modify the proprioceptive dysfunction at brain-level using the vision to reach the brain.
