In page Conjugate gaze palsy:

"

One other type of gaze palsy is a horizontal saccadic palsy. Saccades are very quick intermittent eye movements.[4] The paramedian pontine reticular formation(PPRF), also in the pons is responsible for saccadic movement, relaying signals to the abducens nucleus.[5] Lesions in the PPRF cause what would be saccadic horizontal eye movements to be much slower or in the case of very severe lesions, nonexistent.[3] Horizontal gaze palsies are known to be linked to Progressive Scoliosis.[6] This occurs because pathways controlling saccadic movements are disrupted by the lesion and only slow movements controlled by a different motor pathway are unaffected.[citation needed]
