Assessment of vertical component of gaze deviation in acute PICA occlusion on Computed Tomography

In our recent article “Radiological Horizontal Gaze Deviation in the Setting of Acute PICA Territory Ischemia: A Potential Mimic of Large Vessel Occlusion”, we raised the possibility that the horizontal gaze deviation (HGD) seen in PICA stroke patients may be one component of rotational nystagmus [1]. PICA occlusion could result in vermis ischemia and thus, lead to disruption of pathway involving the deep cerebellar nuclei and stimulate fastigial neurons that is responsible saccade generation may fire result in oblique vertical saccades [2–4].
