Slow Horizontal, Vertical and Oblique Saccades in Spinocerebellar Ataxia Type I | This is a patient presenting with horizontal diplopia who was found to have divergence insufficiency, an esotropia greater at distance than near in the absence of abduction paresis. She also had very slow saccades, more so vertically than horizontally. This is particularly noticeable when asking h... | Image/MovingImage |

Supine Head-Hanging Test | The supine head-hanging test is more sensitive for AC-BPPV, but it does not differentiate laterality, as both canals are stimulated at the same time [1-3]. When the individual returns to a seated position, the otoconia should hypothetically move closer to the utricle, which continues their ampullofu... | Text |

Supine Roll Test | Supine roll test: used to test for horizontal canal (HC) BPPV. While horizontal nystagmus due to HC-BPPV is often seen with DH, the roll test will usually maximize nystagmus and vertigo with the HC variant. The patient can be guided through a self-administered supine roll test while lying on the flo... | Image/MovingImage |

Supine Roll Test/Pagnini-McClure Test | The supine roll test or the Pagnini-McClure Test is used to assess for horizontal canal benign paroxysmal positional vertigo. A test is positive when a patient reports vertigo, dizziness, or sensation of movement or falling with nystagmus present. Apogetropic nystagmus is indicative of cupulolithias... | Text |

Test of Latency | The Test of Latency is used to identify which side is involved for patients with horizontal canal BPPV and is used in conjunction with the Supine Roll Test. For canalithiasis, lateralization is considered the side with a shorter latency time. For cupulolithasis, lateralization is considered the side... | Text |

Third and Sixth Nerve Palsies Due to Cavernous Sinus Meningioma | This is a 60-year-old woman with a large meningioma that was compressing the right cavernous sinus. Examination demonstrated a pupil-involving right 3rd nerve palsy with near complete external ophthalmoplegia (involving levator palpebrae, medial rectus, superior rectus, inferior rectus). There was a... | Image/MovingImage |
