Unilateral lesions of the PPRF produce characteristic findings:

Loss of horizontal saccades directed towards the side of the lesion, no matter the current position of gaze

Contralateral gaze deviation (acute lesions, such as early stroke, only)

Gaze-evoked lateral nystagmus on looking away from the side of the lesion

Bilateral lesions produce horizontal gaze palsy and slowing of vertical saccades

Unilateral irritative stimulation of a FEF causes conjugate gaze contralateral to the stimulation. Conversely, a unilateral destructive lesion of the FEF causes conjugate gaze towards the lesion...
