gaze palsy

an inability to move the eyes, either by saccades or smooth-pursuit eye movements, past mid position in a particular direction, although the eye muscles are capable of contraction. Typical forms are vertical gaze palsy (affecting up–down movements) and horizontal gaze palsy (affecting left–right movements); in complete gaze palsy, gaze shifts are restricted in all directions. Gaze palsy can be caused by injury to the brainstem, thalamus, or posterior occipitotemporal, parietal, or frontal cortex. It leads to a restriction of the field of regard. Also called gaze paresis.
