HINTS (Head Impulse, Nystagmus, Test of Skew) exam demonstrated a central pattern: 1) Head impulse test (HIT) was abnormal to the right and to the left. An abnormal...Image/MovingImage
2 Range of Eye Movements and Evaluation for Nystagmus𝗢𝗿𝗶𝗴𝗶𝗻𝗮𝗹 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: Range: Assesses for motility deficit due to an ocular motor palsy, particularly if a posterior fossa localization is being considered; Nystagmus: Spontaneous nystagmus may or may not be noted and gaze-evoked nystagmus is ...Image/MovingImage
3 The Acute Vestibular Syndrome in MS Due to Middle Cerebellar Peduncle/Root Entry Zone LesionThis is a 13 year-old girl with relatively abrupt onset vertigo and oscillopsia. On exam, there was primarily right-beating nystagmus in primary gaze with a slight upward (upbeat) component, giving the nystagmus an oblique appearance.

6 Acute Vestibular Syndrome With Skew Deviation and Positive Head Impulse Test Due to a Demyelinating LesionThis is a patient who initially presented with the acute vestibular syndrome (AVS, e.g., acute prolonged vertigo, spontaneous nystagmus). ; See https://collections.lib.utah.edu/details?id=187730 for additional history. ; Her HINTS (Head Impulse, Nystagmus, Test of Skew) testing indicated a central e...Image/MovingImage
7 Demonstration of HINTS Examination in a Normal SubjectIn the acute vestibular syndrome - consisting of acute prolonged vertigo, spontaneous nystagmus, imbalance, nausea/vomiting, head motion intolerance which is typically due to vestibular neuritis or posterior fossa stroke - a 3 step test of ocular motor and vestibular function known as HINTS, has hig...Image/MovingImage
