Four cases of an apparently benign ocular motor syndrome of childhood are reported. The features of the disorder are: (1) onset in early life; (2) periods of constant or variably sustained tonic conjugate upward deviation of the eyes; (3) down-beating saccades in attempted downgaze, which are difficult to sustain below the neutral positions; (4) apparently normal horizontal eye movements; (5) frequent relief by sleep; (6) otherwise normal neurological findings apart from mild ataxia, chronic in…

Paroxysmal tonic upgaze is an apparently benign phenomenon with unclear pathophysiology of various proposed mechanisms such as genetic predisposition, immaturity of the brain stem, neurotransmitter depletion, or immune dysregulation.

It is suggested that any insult with periaqueductal mesencephalic gray-matter involvement could be considered the basic condition for this peculiar clinical manifestation of paroxysmal tonic upgaze.

Paroxysmal tonic upgaze of childhood with co-existent absence epilepsy.
A 2-year-old boy who presented with macrocephaly, hypotonia, developmental delay and episodes of eye fluttering, head nodding and unresponsiveness is described, illustrating that paroxysmal tonic upgaze of childhood may co-exist with early onset absence epilepsy.

In all the patients, tonic upgaze episodes disappeared with time to remission, varying from 1 to 4 y, without any therapy and without any change in psychomotor development, EEG and neuroimaging.

Paroxysmal torticollis in infancy.
Persistent upward eye deviation Report of two cases
It was concluded that PUED is not necessarily the consequence of a downward gaze palsy but can also represent a primary dystonic disorder of the superogyric eye muscles, probably the result of a change in the neuronal systems which regulate the upright posture.
Sustained upgaze in coma.
The underlying neuronal mechanism of sustained upgaze appears to be due to total floccular disinhibition resulting in upward drift produced by the biased VOR and the lack of correcting saccades due to cerebral dysfunction releasing the brain stem ocular motor systems from their control.

Coma with sustained upward gaze deviation followed cardiac arrest in 15 patients and prolonged systemic hypotension in 2 patients confirmed the expected diffuse cerebral and cerebellar damage with relative sparing of the brainstem with no focal lesions found in the upper midbrain or pretectum.
Failure of downward gaze: the site and nature of the lesion.
It is suggested that sudden, permanent selective failure of downward gaze accompanied by transient disturbance of consciousness is an embolic syndrome of the posterior thalamosubthalamic or rubral artery.
Selective paralysis of downward gaze caused by bilateral lesions of the mesencephalic periaqueductal gray matter
A patient who had selective paralysis of downward gaze caused by bilateral lesions of the dorsolateral mesencephalic periaqueductal gray (PAG) matter is reported. Her necropsy findings differed from
