Typical ocular bobbing is associated with structural lesions. Benzodiazepines and benztropine are ineffective, while anticonvulsants helped one patient partly but not another , This latter symptomatic deviation is accompanied by upgaze paresis, in contrast to the deviation in healthy neonates, and is attributed to damage to mesencephalic vertical gaze structures. Gaze deviation recovers over 2 weeks on average, but can last a day to several months Inverse bobbing is associated with anoxic encephalopathy due to cardiac , or respiratory arrest, carbon monoxide poisoning , status epilepticus , , or head trauma These transient involuntary deviations are a variation of dystonia or tic.

It has been described with acute obstructive hydrocephalus, sometimes with shunt malfunction , Ocular bobbing initial phase is fast and down a. The episodes are less frequent for a few hours after a nap, though there may be a transient flurry on wakening There was a one-and-a-half syndrome consisting of INO and ipsilateral gaze paresis sparing vestibular movements. Right-sided lesions involve subcortical fronto-parietal regions, and almost invariably have left hemineglect; left-sided lesions causing ipsilateral gaze deviation tend to be much larger, involving the inferior parietal lobule, and have associated aphasia Other Involuntary Eye Movements i. She was in an unconscious state when she was transferred to a nursing home on day Key Clinical Message Roving eye movements are the sign of cortical dysfunction not involving the brainstem. Hyperactivity and learning problems may emerge much later in some cases ,, Age of onset varies between 2 and 20 months ,,, The bobbing resolves over a few weeks. It occurs with bilateral cerebral infarction , and posterior fossa hemorrhage Others postulate that DVD improves vision by suppressing a cyclovertical component of latent nystagmus Paroxysmal tonic upgaze of childhood with ataxia. The prognosis is variable; some patients have recovered well , while others died. Unlike true bobbing, V-pattern pseudobobbing with pretectal signs indicates a potential need for surgical intervention. In some cases the dysconjugacy results from the combination of typical ocular bobbing in one eye with oculomotor nerve palsy in the other eye In rare cases bobbing is synchronized with myoclonic jerks of the head and limbs or with pupillary oscillations This is also known as dissociated vertical divergence, alternating sursumduction, occlusion hypertropia, and double dissociated hyperdeviation Treatment involves discontinuation of provoking drugs and use of anticholinergic agents like benztropine It has been attributed to a combination of diffuse cerebral cortical suppression and lesions of the basal ganglia, especially the lenticular nucleus , though others consider it a non-localizing sign In some cases horizontal eye movements are impaired just prior to death This has been described in two patients with coma from combined phenothiazine and benzodiazepine intoxication The amplitude of movement is variable, usually several millimeters In other cases, ocular bobbing fluctuates from conjugate movements to dysconjugate out-of-phase bobbing, to unilateral or near unilateral bobbing switching from one eye to the other ,,,

This must be scared from the water downward deviation with unambiguous angle esotropia in addition members with unambiguous position and every inspection One such cases have been voted.

Abnormal decussation may disrupt the development of normal binocular vision, but how this leads to DVD is unclear. In others, the damage to the nodulus has likely also impaired prenuclear saccadic structures in the PPRF, eliminating the fast phases of nystagmus.
