See-Saw Nystagmus 2-4
Channel: Moran CORE
Date: 2018-02-08

Example of a patient with see-saw nystagmus, showing how one eye elevates as the other depresses, with the elevating eye intorting as the depressing eye extorts. Shows vertical oscillations with pendular waveforms. Suggests a large structural lesion in the pericellar region (associated with bi-temporal field defects).
