Possible Causes for Ocular Bobbing

Intrapontine Hemorrhage

Spontaneous downward eye movements - ocular bobbing - imply preservation of rostral brainstem gaze centres. smaller unilateral basal pontine lesions show contralateral hemiparesis [gpnotebook.co.uk]

Contralateral hemiparesis, contralateral conjugate gaze paresis, or confusion Brain stem - Tetraparesis, facial weakness, decreased level of consciousness, gaze paresis, ocular [en.wikipedia.org]

bobbing, miosis, or autonomic instability Cerebellum - Ataxia, usually beginning in the trunk, ipsilateral facial weakness, ipsilateral sensory loss, gaze paresis, skew deviation [en.wikipedia.org]

Pontine Glioma

A 36-year-old male was admitted with a 10-year history of gradually progressive left ear hearing loss, diplopia and right hemiparesis. Magnetic resonance imaging showed a left lateral pontine enhancing tumour and an additional cerebellopontine angle epidermoid tumour in close proximity forming a collision tumour.

Metabolic Encephalopathy

A patient with atypical ocular bobbing resulting from metabolic encephalopathy is described. [ncbi.nlm.nih.gov]

Neurologic examination showed no signs of brainstem dysfunction, and postmortem examination failed to disclose any changes in sites associated with ocular bobbing in other [ncbi.nlm.nih.gov]

This is the first demonstration of functional disturbance in brainstem loci that are thought to be responsible for the infrequently observed ocular bobbing in metabolic encephalopathy [ncbi.nlm.nih.gov]

Convergence Nystagmus

Because of a faster downstroke and appropriate amplitude, these movements were usually diagnosed as ocular bobbing. [ncbi.nlm.nih.gov]

Diagnostic Considerations Ocular oscillations that mimic nystagmus include the following: Ocular flutter Opsoclonus Ocular bobbing Ocular dysmetria Superior oblique myokymia [emedicine.medscape.com]

However, their "V" pattern, the generally faster rate, and pretectal, rather than pontine-associated, signs distinguished them from true ocular bobbing. [ncbi.nlm.nih.gov]
