Because the riMLF projections to the depressors are ipsilateral whereas the projections to the elevators are bilateral, a unilateral riMLF lesion tends to affect downward more than …

Supranuclear Gaze Pathways - Eye Notes

The PPRF is located anterior and lateral to the medial longitudinal fasciculus (MLF). It receives input from the superior colliculus via the predorsal bundle and from the frontal eye fields via frontopontine fibers. The rostral PPRF probably coordinates vertical saccades; the caudal PPRF may be the generator of … See more The paramedian pontine reticular formation, also known as PPRF or paraabducens nucleus, is part of the pontine reticular formation, a brain region without clearly defined borders in the center of the See more • Internuclear ophthalmoplegia • Multiple sclerosis • One and a half syndrome See more 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 See more WebJun 4, 2016 · Rarely, a primary position esotropia occurs, most likely due to involvement of the abducens nerve fascicle superimposed upon lesions of the PPRF and MLF (Wall, 1983). The one-and-a-half syndrome may be associated with ocular bobbing and, more often, facial nerve palsy (the “eight-and-a-half syndrome”) (Eggenberger, 1998). http://shutoku.fc2web.com/special_subjects/4th_grade/S7/report/5.html esola池袋 フロアマップ
