Visual-Vestibular Integration Dysfunction
Visual-vestibular integration dysfunction is a sensory disorder in which the brain cannot properly process and combine information from the visual and vestibular systems. The visual-vestibular system integrates information from the inner ear and eye to provide spatial awareness, balance, and directional concepts. The area of system convergence is the superior colliculus. When damaged, the superior colliculus can no longer incorporate information, leading to deficits such as: the inability to maintain a single image as an object approaches, directional incomprehension, and sensitivity to light and sound.
