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…

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.

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.
