A vertical gaze palsy (VGP) is a conjugate, bilateral, limitation of the eye movements in upgaze and/or downgaze. VGP can affect functional eye movements by selectively involving the …

Up gaze palsy is due to damage of the vertical gaze center (rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF) and the interstitial nucleus of Cajal (INC)) and its …

The author reviews the various manifestations and causes of vertical gaze palsy. These can affect upgaze, downgaze, or both, usually affecting saccades primarily. The localization can be at …

Abnormalities in eye movements can be caused by palsy of isolated ocular muscles, palsy of conjugate movements (gaze), or both . Gaze disorders are reviewed in this topic. Palsies of …

Conjugate gaze palsies most commonly affect horizontal gaze; downward gaze is affected least often. Common causes include strokes for horizontal gaze palsies, midbrain lesions (usually …

2020年2月5日 · Bilateral lesions of the riMLF or its descending fibers will result in a more severe defect of vertical gaze than that due to unilateral lesions. Downward saccades are typically …

Ocular motor symptoms include initial vertical gaze palsy, with later horizontal gaze palsy and the picture of complete ophthalmoplegia (with impaired saccade and smooth pursuit systems). …

In early stages of vertical supranuclear gaze paresis/palsy, before prominent gaze restriction, the disproportionally slowed vertical saccadic velocity (compared with horizontal) presents with the …

Thalamic lesions can produce acute vertical gaze palsy. The vertical gaze abnormality in paramedian thalamic infarctions is speculated to be due to interruption of supranuclear fibers …

2023年2月21日 · Vertical gaze palsy includes Parinaud's syndrome, progressive supranuclear palsy, and skew deviation. Paralysis of the upward vertical gaze palsy is the most common …
