Description
This is characterized by an initial fast phase downward, followed by a slow phase up, which is the reverse of nystagmus, where a corrective fast phase follows the slow phase. Most patients with bobbing have a large pontine lesion and are comatose with paralyzed horizontal eye movements. The patient in this clip had a pontine glioma. Three other less common vertical oscillations are described.
