Duane's Syndrome | Example of patient with Duane's Syndrome. Patient is led through instructions for pursuit. | Image/MovingImage |
52 |
|
Measuring Visual Acuity | Demonstration on self of visual acuity exam, using a standard card. | Image/MovingImage |
53 |
|
Testing the Visual Fields | Demonstration of various methods of testing visual fields, including counting fingers, motion, and color of several objects. | Image/MovingImage |
54 |
|
Dilation Lag | Two examples of dilation lag (Horner's syndrome). In the first example, the right pupil dilates much faster than the left pupil when the light is turned out. In the second example, the left pupil dilates much faster than the right pupil when the light is turned out. Discussion of methods of document... | Image/MovingImage |

|
RAPD Present | This clip demonstrates the technique used to determine that Relative Afferent Pupillary Defect (RAPD) is present in a patient. | Image/MovingImage |
56 |
|
Transillumination - Lisch Nodules | Demonstration of transillumination of the Lisch nodules on a patient with neurofibromatosis. Shows how Lisch nodules that were not very visible in slit-lamp examination are better seen with transillumination, which may therefore be useful in detecting Lisch nodules earlier in children where they are... | Image/MovingImage |
57 |
|
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 |
58 |
|
How to Use the Direct Ophthalmoscope in an Exam | Demonstration of using the direct ophthalmoscope to examine the optic disc. Covers hand placement , which eye to use, and distance from patient. | Image/MovingImage |
59 |
|
Tour of the Fundus | This clip demonstrates the funduscopic examination technique. | Image/MovingImage |
60 |
|
Aberrant Regeneration of the Third | Patient with a right third nerve palsy demonstrates ptosis, anisocoria and ophthalmoplegia. During attempted downgaze, the right upper lid flutters back up (aberrant movement) and remains retracted. | Image/MovingImage |
61 |
|
Bilateral Internuclear Ophthalmoplegia | Example of patient with bilateral internuclear ophthalmoplegia. Patient is led through instructions for direction and distance of gaze. | Image/MovingImage |
62 |
|
Brainstem Trauma | | Image/MovingImage |

|
Cogan's Lid Twitch | | Image/MovingImage |

|
Third Nerve Palsy | Patient with third nerve palsy (no audio) | Image/MovingImage |
65 |
|
Vestibular Nystagmus | Example of patient with vestibular nystagmus. Patient is led through instructions for direction of gaze. Shown also with Frenzel goggles. | Image/MovingImage |
66 |
|
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 |
67 |
|
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 |
68 |
|
Dissociated Nystagmus | Example of a patient with dissociated nystagmus. Demonstrates difference in movements between each eye. | Image/MovingImage |
69 |
|
Internuclear Ophthalmoplegia (2 Examples) | Two examples of patients with internuclear ophthalmoplegia. First patient has a right internuclear ophthalmoplegia. Patient had subacute bacterial endocarditis with a bacterial abscess in the brain stem. Ductions and gaze to the right look good, but when gazing to the left, the right eye does not ad... | Image/MovingImage |
70 |
|
Latent Nystagmus | Example of a patient with latent nystagmus. Demonstrates a lack of oscillations in forward gaze, followed by the occlusion of each eye, showing how this generates a jerking oscillation in the non-occluded eye away from the occluded eye. | Image/MovingImage |
71 |
|
Opsoclonus | Example of patients with opsoclonus, a saccadic abnormality. | Image/MovingImage |
72 |
|
Paradoxical Constriction of Pupils to Darkness (Flynn Phenomenon) | Example of patients both with and without paradoxical constriction of pupils. Observed in many congenital retinal disorders, such as achromatopsia, congenital stationary night-blindness, and Leber's congenital amaurosis. Sometimes seen in optic nerve disorders, such as dominant optic atrophy. | Image/MovingImage |
73 |
|
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 |
74 |
|
Spasm of the Near Reflex | Example of patient with spasm of the near reflex and voluntary nystagmus. Discussion of similar-looking conditions (e.g. six nerve palsy, limitation of abduction, lateral rectus muscle problems) and how to tell them apart from spasm of the near reflex by observing the myosis evoked by the near respo... | Image/MovingImage |
