RESUMO
Skew deviation é o desalinhamento vertical dos olhos causado por disfunção unilateral no tronco cerebral, cerebelo ou sistema vestibular periférico, comprometendo as vias por onde transitam impulsos dos órgãos otolíticos aos núcleos oculomotores. Está frequentemente associado a torção ocular e inclinação da cabeça, compondo, assim, a ocular tilt reaction. Neste artigo os autores ressaltam aspectos históricos, fisiológicos, etiopatogênicos e clínicos que contribuem para caracterizar ambas as condições, além da diferenciação clínica com a paralisia do nervo troclear.
ABSTRACT
Skew deviation is the vertical misalignment of the eyes caused by unilateral dysfunction in the brain stem, cerebellum or peripheral vestibular system, resulting imbalance in otolith input to the oculo-motor system. It's often associated with ocular torsion and head tilt, which together comprise the ocular tilt reaction. In this article the authors emphasize the historical, physiological, etiopathogenesis and clinical aspects that contribute to characterize both conditions, and help to differentiate them clinically from trochlear nerve palsy.
