Visually induced vertigo (VV) can occur in patients with balance disorders who rely heavily on visual cues. Additional eye muscle or central nervous system issues may worsen postural instability in these individuals.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Vestibular System

Background:

  • Visually induced vertiginous symptoms (VV) are often associated with peripheral vestibular disorders.
  • Central nervous system (CNS) involvement, such as cerebellar degeneration or brainstem stroke, can also manifest with VV.
  • Strabismic symptoms, including diplopia and ocular muscle weakness, may coexist with VV.

Purpose of the Study:

  • To investigate neuro-otological and posturography findings in patients experiencing VV.
  • To explore the relationship between visual dependence, CNS disease, strabismic symptoms, and postural control in VV patients.

Main Methods:

  • Assessment of 15 patients with VV.
  • Neuro-otological examinations.
  • Posturography with full-field visual motion stimulation.

  • Evaluation for CNS and strabismic symptoms.

    • Main Results:

    • Most patients had peripheral vestibular disorders, but two had CNS conditions.
    • Five patients exhibited significant body sway during visual stimulation, including those with CNS disease.
    • Four of the five patients with increased sway also had strabismic symptoms.

    Conclusions:

    • High visual field dependence in patients with balance disorders may contribute to VV.
    • Co-occurring CNS or strabismic symptoms can impair the resolution of conflicting visual stimuli, leading to poor postural reactions in VV.
