Horizontal gaze palsy : ウィキペディア英語版 | Horizontal gaze palsy
A gaze palsy is the paresis of conjugate eye movements. Horizontal gaze palsy may be caused by lesions in the cerebral hemispheres, which cause paresis of gaze away from the side of the lesion, or from brain stem lesions, which, if they occur below the crossing of the fibers from the frontal eye fields in the caudal midbrain, will cause weakness of gaze toward the side of the lesion. Another way to remember this is that patients with hemisphere lesions look toward their lesion, while patients with pontine gaze palsies look away from their lesions. Note that patients with gaze palsy still have conjugate eye movements and therefore do not complain of diplopia. The human Robo gene acts as a receptor for a midline repulsive cue. When Robo is mutated, the longitudinal tract formation is disrupted and therefore normal neuronal connections cannot form. This leads to the reduced hindbrain volume and scoliosis, which are common symptoms of horizontal gaze palsy. ==References==
