Can vestibular problems cause visual snow and after images?
The vestibular system and the visual system are highly integrated. For example, when you turn your head to the right but keep your eyes straight ahead, a specific reflex tells the brain that just your head is moving, and it helps you to not become dizzy. (Vestibulo-ocular Reflex) If your balance problem is occurring because of problems more centrally (brainstem or cortex related) it can be common to have vision problems. If the rehabilitation you are doing is vestibular/balance rehab., I assume you have seen a neuro-otologist or otolaryngologist (Ear, Nose, and Throat doctor). At your next appointment, mention the change in vision, and they will help determine if it is due to purely visual changes, blood pressure changes from movements in rehab, the vestibular system in the inner ear, or if it is a more central (Brainstem/cortex) finding. Good luck!
