|
The Wall-Eyed Potato Farmer | Young man presenting with apparent episodic neurologic evants that initially was thought to be multiple sclerosis, but as time went on, he had progressive changes in his neurologic exam and in his imaging findings. Brain biopsy revealed Gliomatosis cerebri. Anatomy: Brain Stem; Pons; Midbrain. Patho... | |

Opsoclonus | Example of patients with opsoclonus, a saccadic abnormality. | Image/MovingImage |

7 |
|
Dissociated Nystagmus | Example of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye. | Image/MovingImage |
8 |
|
Abducting (Dissociated) Nystagmus | Example of a patient with abducting (dissociated) nystagmus. Patient has a subtle internuclear ophthalmoplegia. Right eye has right-beating jerk nystagmus, with smaller oscillations in the left eye. Disease/Diagnosis: Abducting Nystagmus | Image/MovingImage |
9 |
|
Brun's Nystagmus | Observation of patient with Brun's Nystagmus. Shows patient gazing to the right and the nystagmus beating in the direction of the gaze. | Image/MovingImage |
10 |
|
Cogan's Lid Twitch | Example of a patient with Cogan's lid twitch, with discussion of how to detect it in an exam. | Image/MovingImage |
11 |
|
Congenital Ocular Motor Apraxia | Two examples of congenital ocular motor apraxia. Patients have trouble initiating saccades, and compensate with head movement. Discussion of how to distinguish this condition from simply not seeing well. | Image/MovingImage |
12 |
|
Downbeat Nystagmus | Example of patients with downbeating jerk nystagmus. Demonstrates how oscillations grow more prominent when the patient gazes down or laterally. Discusses some causes, including Arnold-Chiari malformation, infarction, and demyelination. | Image/MovingImage |
13 |
|
Physiologic (End-Gaze) Nystagmus | Demonstration of physiological nystagmus, where oscillations do not represent pathology, but occur when the patient's gaze is drawn too far laterally. | Image/MovingImage |
14 |
|
Pulsating Exophthalmos | Example of a patient with neurofibromatosis with an absent sphenoid wing. Shows left eye pulsating back and forth with the pulse from front and side views. | Image/MovingImage |
15 |
|
Rotary Nystagmus | Example of a patient with rotary nystagmus, showing occasional counterclockwise rotary movements of both eyes. Seen more in intrinsic disorders of the brainstem. | Image/MovingImage |
16 |
|
Square Wave Jerks | Example of patient with square wave jerks. Discussion of difference between square wave jerks (saccadic oscillations) and horizontal nystagmus. | Image/MovingImage |
17 |
|
Transillumination - Ciliary Body Neurofibromas | Example of transillumination on a patient with neurofibromatosis, but without Lisch nodules. Shows suspected neurofibromas in the ciliary body. | Image/MovingImage |
18 |
|
Upbeat Nystagmus | Example of a patient with upbeat nystagmus. Shows vertical jerk nystagmus with fast phases in the up direction. Localizes to brain stem, and occurs with strokes, demyelination, and tumors. | Image/MovingImage |
19 |
|
Vestibular Nystagmus | Discussion of vestibular nystagmus. Seen with peripheral disorders and central disorders, and in two varieties: spontaneous and positional. Horizontal jerk with small amplitude. | Image/MovingImage |
20 |
|
Voluntary Nystagmus | Example of patient with voluntary nystagmus. Discussion of how a lack of uniform, patterned movement of the eyes along with associated lid movements suggests that activity is voluntary. | Image/MovingImage |
