The ophthalmologist's main task in the interdisciplinary approach to vertigo is the examination of ocular motility to rule out central ocular motility disorders. Further neuro-ophthalmological examinations (e.g. pupil reactions and optic disc) may provide unspecific findings that can be helpful. The ophthalmologist may be able to deliver puzzle-solving key findings in some multidisciplinary diseases (e.g. Cogan I, Vogt-Koyanagi-Harada disease and Behcet's disease). Ocular alterations do not cause vertigo but a variety of more diffuse complaints that some patients refer to as vertigo.
