Visual vertigo (VV) refers to the sensation of disequilibrium a person can feel when seeing certain patterns (such as a carpet) or doing visual tasks (such as reading or driving). The idea that visual input can make a person feel disequilibrium is controversial; not all investigators agree on this. VV is usually diagnosed and managed by neuro-optometrists. VV is often treated with vision therapy (visual exercises), and sometimes with special glasses lenses, prisms, or tints. VV can happen in isolation (“by itself”), but it can also happen at the same time as another “dizzy disease,” such as inner ear problems, so a screening vestibular workup may be appropriate before referral to a neuro-optometrist.
