ⓘ Horizontal gaze palsy

A gaze palsy is the paresis of conjugate eye movements.

Horizontal gaze palsy may be caused by lesions of the cerebral hemispheres, which cause paresis of gaze from the side of the lesion, or lesions of the brain, which, if they occur below the crossing of fibers from the frontal eye field in the caudal mid-brain, causing weakness of the gaze on the affected side. This will result in horizontal gaze deviations from uncontested basis, without the changes extraoculary muscles. Another way to remember is that patients with lesions of the hemisphere to watch their destruction and in patients with paresis of Pontine gaze away from their homes. Please note that patients with paralysis of the eye even conjugate eye movements and therefore does not complain of diplopia.

The human gene Robo acts as a receptor for the take-off line of the Cue. When the ro is mutated, the formation of a longitudinal tract is disrupted and therefore, normal neural pathways do not form. This leads to reduced volume of instincts and scoliosis, which are common symptoms of horizontal gaze palsy.
